This README contains details about the cgminer RPC API
It also includes some detailed information at the end,
about using miner.php
If you start cgminer with the "--api-listen" option, it will listen on a
simple TCP/IP socket for single string API requests from the same machine
running cgminer and reply with a string and then close the socket each time
If you add the "--api-network" option, it will accept API requests from any
network attached computer.
You can only access the comands that reply with data in this mode.
By default, you cannot access any privileged command that affects the miner -
you will receive an access denied status message see --api-allow below.
You can specify IP addresses/prefixes that are only allowed to access the API
with the "--api-allow" option e.g. --api-allow W:192.168.0.1,10.0.0/24
will allow 192.168.0.1 or any address matching 10.0.0.*, but nothing else
IP addresses are automatically padded with extra '.0's as needed
Without a /prefix is the same as specifying /32
0/0 means all IP addresses.
The 'W:' on the front gives that address/subnet privileged access to commands
that modify cgminer (thus all API commands)
Without it those commands return an access denied status.
See --api-groups below to define other groups like W:
Privileged access is checked in the order the IP addresses were supplied to
"--api-allow"
The first match determines the privilege level.
Using the "--api-allow" option overides the "--api-network" option if they
are both specified
With "--api-allow", 127.0.0.1 is not by default given access unless specified
More groups (like the privileged group W:) can be defined using the
--api-groups command
Valid groups are only the letters A-Z (except R & W are predefined) and are
not case sensitive
The R: group is the same as not privileged access
The W: group is (as stated) privileged access (thus all API commands)
To give an IP address/subnet access to a group you use the group letter
in front of the IP address instead of W: e.g. P:192.168.0/32
An IP address/subnet can only be a member of one group
A sample API group would be:
--api-groups P:switchpool:enablepool:addpool:disablepool:removepool:poolpriority:*
This would create a group 'P' that can do all current pool commands and all
non-priviliged commands - the '*' means all non-priviledged commands
Without the '*' the group would only have access to the pool commands
Defining multiple groups example:
--api-groups Q:quit:restart:*,S:save
This would define 2 groups:
Q: that can 'quit' and 'restart' as well as all non-priviledged commands
S: that can only 'save' and no other commands
The RPC API request can be either simple text or JSON.
If the request is JSON (starts with '{'), it will reply with a JSON formatted
response, otherwise it replies with text formatted as described further below.
The JSON request format required is '{"command":"CMD","parameter":"PARAM"}'
(though of course parameter is not required for all requests)
where "CMD" is from the "Request" column below and "PARAM" would be e.g.
the CPU/GPU number if required.
An example request in both formats to set GPU 0 fan to 80%:
gpufan|0,80
{"command":"gpufan","parameter":"0,80"}
The format of each reply (unless stated otherwise) is a STATUS section
followed by an optional detail section
From API version 1.7 onwards, reply strings in JSON and Text have the
necessary escaping as required to avoid ambiguity - they didn't before 1.7
For JSON the 2 characters '"' and '\' are escaped with a '\' before them
For Text the 4 characters '|' ',' '=' and '\' are escaped the same way
Only user entered information will contain characters that require being
escaped, such as Pool URL, User and Password or the Config save filename,
when they are returned in messages or as their values by the API
For API version 1.4 and later:
The STATUS section is:
STATUS=X,When=NNN,Code=N,Msg=string,Description=string|
STATUS=X Where X is one of:
W - Warning
I - Informational
S - Success
E - Error
F - Fatal (code bug)
When=NNN
Standard long time of request in seconds
Code=N
Each unique reply has a unigue Code (See api.c - #define MSG_NNNNNN)
Msg=string
Message matching the Code value N
Description=string
This defaults to the cgminer version but is the value of --api-description
if it was specified at runtime.
For API version 1.10 and later:
The list of requests - a (*) means it requires privileged access - and replies are:

none There is no reply section just the STATUS section
stating the results of setting GPU N vddc to V
save|filename (*)
none There is no reply section just the STATUS section
stating success or failure saving the cgminer config
to filename
The filename is optional and will use the cgminer
default if not specified
quit (*) none There is no status section but just a single "BYE"
reply before cgminer quits
notify NOTIFY The last status and history count of each devices problem
This lists all devices including those not supported
by the 'devs' command
e.g. NOTIFY=0,Name=GPU,ID=0,Last Well=1332432290,...|
privileged (*)
none There is no reply section just the STATUS section
stating an error if you do not have privileged access
to the API and success if you do have privilege
The command doesn't change anything in cgminer
pgaenable|N (*)
none There is no reply section just the STATUS section
stating the results of the enable request
You cannot enable a PGA if it's status is not WELL
This is only available if PGA mining is enabled
pgadisable|N (*)
none There is no reply section just the STATUS section
stating the results of the disable request
This is only available if PGA mining is enabled
pgaidentify|N (*)
none There is no reply section just the STATUS section
stating the results of the identify request
This is only available if PGA mining is enabled
and currently only BFL singles support this command
On a BFL single it will flash the led on the front
of the device for appoximately 4s
All other non BFL PGA devices will return a warning
status message stating that they dont support it
This adds a 4s delay to the BFL share being processed
so you may get a message stating that procssing took
longer than 7000ms if the request was sent towards
the end of the timing of any work being worked on
e.g.: BFL0: took 8438ms - longer than 7000ms
You should ignore this
devdetails DEVDETAILS Each device with a list of their static details
This lists all devices including those not supported
by the 'devs' command
e.g. DEVDETAILS=0,Name=GPU,ID=0,Driver=opencl,...|
restart (*) none There is no status section but just a single "RESTART"
reply before cgminer restarts
stats STATS Each device or pool that has 1 or more getworks
with a list of stats regarding getwork times
The values returned by stats may change in future
versions thus would not normally be displayed
Device drivers are also able to add stats to the
end of the details returned
check|cmd COMMAND Exists=Y/N, <- 'cmd' exists in this version
Access=Y/N| <- you have access to use 'cmd'
failover-only|true/false (*)
none There is no reply section just the STATUS section
stating what failover-only was set to
coin COIN Coin mining information:
Hash Method=sha256/scrypt,
Current Block Time=N.N, <- 0 means none
Current Block Hash=XXXX..., <- blank if none
LP=true/false| <- LP is in use on at least 1 pool
debug|setting (*)
DEBUG Debug settings
The optional commands for 'setting' are the same as
the screen curses debug settings
You can only specify one setting
Only the first character is checked (case insensitive):
Silent, Quiet, Verbose, Debug, RPCProto, PerDevice,
WorkTime, Normal
The output fields are (as above):
Silent=true/false,
Quiet=true/false,
Verbose=true/false,
Debug=true/false,
RPCProto=true/false,
PerDevice=true/false,
WorkTime=true/false|
setconfig|name,N (*)
none There is no reply section just the STATUS section
stating the results of setting 'name' to N
The valid values for name are currently:
queue, scantime, expiry
N is an integer in the range 0 to 9999
usbstats USBSTATS Stats of all LIBUSB mining devices except ztex
e.g. Name=MMQ,ID=0,Stat=SendWork,Count=99,...|
pgaset|N,opt[,val] (*)
none There is no reply section just the STATUS section
stating the results of setting PGA N with opt[,val]
This is only available if PGA mining is enabled
If the PGA does not support any set options, it will
always return a WARN stating pgaset isn't supported
If opt=help it will return an INFO status with a
help message about the options available
The current options are:
MMQ opt=clock val=160 to 230 (and a multiple of 2)
zero|Which,true/false (*)
none There is no reply section just the STATUS section
stating that the zero, and optional summary, was done
If Which='all', all normal cgminer and API statistics
will be zeroed other than the numbers displayed by the
usbstats and stats commands
If Which='bestshare', only the 'Best Share' values
are zeroed for each pool and the global 'Best Share'
The true/false option determines if a full summary is
shown on the cgminer display like is normally displayed
on exit.
When you enable, disable or restart a GPU or PGA, you will also get Thread messages
in the cgminer status window
The 'poolpriority' command can be used to reset the priority order of multiple
pools with a single command - 'switchpool' only sets a single pool to first priority
Each pool should be listed by id number in order of preference (first = most
preferred)
Any pools not listed will be prioritised after the ones that are listed, in the
priority order they were originally
If the priority change affects the miner's preference for mining, it may switch
immediately
When you switch to a different pool to the current one (including by priority
change), you will get a 'Switching to URL' message in the cgminer status
windows
Obviously, the JSON format is simply just the names as given before the '='
with the values after the '='
If you enable cgminer debug (-D or --debug) or, when cgminer debug is off,
turn on debug with the API command 'debug|debug' you will also get messages
showing some details of the requests received and the replies
There are included 4 program examples for accessing the API:
api-example.php - a php script to access the API
usAge: php api-example.php command
by default it sends a 'summary' request to the miner at 127.0.0.1:4028
If you specify a command it will send that request instead
You must modify the line "$socket = getsock('127.0.0.1', 4028);" at the
beginning of "function request($cmd)" to change where it looks for cgminer
API.java/API.class
a java program to access the API (with source code)
usAge is: java API command address port
Any missing or blank parameters are replaced as if you entered:
java API summary 127.0.0.1 4028
api-example.c - a 'C' program to access the API (with source code)
usAge: api-example [command [ip/host [port]]]
again, as above, missing or blank parameters are replaced as if you entered:
api-example summary 127.0.0.1 4028
miner.php - an example web page to access the API
This includes buttons and inputs to attempt access to the privileged commands
See the end of this API-README for details of how to tune the display
and also to use the option to display a multi-rig summary

----------------------------------------
miner.php
=========
miner.php is a PHP based interface to the cgminer RPC API
(referred to simply as the API below)
It can show rig details, summaries and input fields to allow you to change
cgminer
You can also create custom summary pages with it
It has two levels to the security:
1) cgminer can be configured to allow or disallow API access and access level
security for miner.php
2) miner.php can be configured to allow or disallow privileged cgminer
access, if cgminer is configured to allow privileged access for miner.php
---------
To use miner.php requires a web server with PHP
Basics: On xubuntu 11.04, to install apache2 and php, the commands are:
sudo apt-get install apache2
sudo apt-get install php5
sudo /etc/init.d/apache2 reload
On Fedora 17:
yum install httpd php
systemctl restart httpd.service
systemctl enable httpd.service --system
On windows there are a few options.
Try one of these (apparently the first one is easiest - thanks jborkl)
http://www.easyphp.org/
http://www.apachefriends.org/en/xampp.html
http://www.wampserver.com/en/
---------
The basic cgminer option to enable the API is:
--api-listen
or in your cgminer.conf
"api-listen" : true,
(without the ',' on the end if it is the last item)
If the web server is running on the cgminer computer, the above
is the only change required to give miner.php basic access to
the cgminer API
-
If the web server runs on a different computer to cgminer,
you will also need to tell cgminer to allow the web server
to access cgminer's API and tell miner.php where cgminer is
Assuming a.b.c.d is the IP address of the web server, you
would add the following to cgminer:
--api-listen --api-allow a.b.c.d
or in your cgminer.conf
"api-listen" : true,
"api-allow" : "a.b.c.d",
to tell cgminer to give the web server read access to the API
You also need to tell miner.php where cgminer is.
Assuming cgminer is at IP address e.f.g.h, then you would
edit miner.php and change the line
$rigs = array('127.0.0.1:4028');
to
$rigs = array('e.f.g.h:4028');
See --api-network or --api-allow for more access details
and how to give write access
---------
Once you have a web server with PHP running
copy your miner.php to the main web folder
On Xubuntu 11.04
/var/www/
On Fedora 17
/var/www/html/
On Windows
see your windows Web/PHP documentation
Assuming the IP address of the web server is a.b.c.d
Then in your web browser go to:
http://a.b.c.d/miner.php
Done :)
---------
The rest of this documentation deals with the more complex
functions of miner.php, using myminer.php, creaing custom
summaries and displaying multiple cgminer rigs
---------
If you create a file called myminer.php in the same web folder
where you put miner.php, miner.php will load it when it runs
This is useful, to put any changes you need to make to miner.php
instead of changing miner.php
Thus if you update/get a new miner.php, you won't lose the changes
you have made if you put all your changes in myminer.php
(and don't change miner.php at all)
A simple example myminer.php that defines 2 rigs
(that I will keep referring to further below) is:
<?php
#
$rigs = array('192.168.0.100:4028:A', '192.168.0.102:4028:B');
#
?>
Changes in myminer.php superscede what is in miner.php
However, this is only valid for variables in miner.php before the
2 lines where myminer.php is included by miner.php:
if (file_exists('myminer.php'))
include_once('myminer.php');
Every variable in miner.php above those 2 lines, can be changed by
simply defining them in your myminer.php
So although miner.php originally contains the line
$rigs = array('127.0.0.1:4028');
if you created the example myminer.php given above, it would actually
change the value of $rigs that is used when miner.php is running
i.e. you don't have to remove or comment out the $rigs line in miner.php
It will be superceded by myminer.php
---------
The example.php above also shows how to define more that one rig to
be shown my miner.php
Each rig string is 2 or 3 values seperated by colons ':'
They are simply an IP address or host name, followed by the
port number (usually 4028) and an optional Name string
miner.php displays rig buttons that will show the defails of a single
rig when you click on it - the button shows either the rig number,
or the 'Name' string if you provide it
PHP arrays contain each string seperated by a comma, but no comma after
the last one
So an example for 3 rigs would be:
$rigs = array('192.168.0.100:4028:A', '192.168.0.102:4028:B', '192.168.0.110:4028:C');
Of course each of the rigs listed would also have to have the API
running and be set to allow the web server to access the API - as
explained before
---------
So basically, any variable explained below can be put in myminer.php
if you wanted to set it to something different to it's default value
and did not want to change miner.php itself every time you updated it
Below is each variable that can be changed and an explanation of each
---------
Default:
$dfmt = 'H:i:s j-M-Y \U\T\CP';
Define the date format used to print full length dates
If you get the string 'UTCP' on the end of your dates shown, that
means you are using an older version of PHP and you can instead use:
$dfmt = 'H:i:s j-M-Y \U\T\CO';
The PHP documentation on the date format is here:
http://us.php.net/manual/en/function.date.php
---------
Default:
$title = 'Mine';
Web page title
If you know PHP you can of course use code to define it e.g.
$title = 'My Rig at: '.date($dfmt);
Which would set the web page title to something like:
My Rig at: 10:34:00 22-Aug-2012 UTC+10:00
---------
Default:
$readonly = false;
Set $readonly to true to force miner.php to be readonly
This means it won't allow you to change cgminer even if the cgminer API
options allow it to
If you set $readonly to false then it will check cgminer 'privileged'
and will show input fields and buttons on the single rig page
allowing you to change devices, pools and even quit or restart
cgminer
However, if the 'privileged' test fails, the code will set $readonly to
true
---------
Default:
$userlist = null;
Define password checking and default access
null means there is no password checking
$userlist is an array of 3 arrays e.g.
$userlist = array('sys' => array('boss' => 'bpass'),
'usr' => array('user' => 'upass', 'pleb' => 'ppass'),
'def' => array('Pools'));
'sys' is an array of system users and passwords (full access)
'usr' is an array of user level users and passwords (readonly access)
'def' is an array of custompages that anyone not logged in can view
Any of the 3 can be null, meaning there are none of that item
All validated 'usr' users are given $readonly = true; access
All validated 'sys' users are given the $readonly access you defined
If 'def' has one or more values, and allowcustompages is true, then
anyone without a password can see the list of custompage buttons given
in 'def' and will see the first one when they go to the web page, with
a login button at the top right
From the login page, if you login with no username or password, it will
show the first 'def' custompage (if there are any)
If you are logged in, it will show a logout button at the top right
---------
Default:
$notify = true;
Set $notify to false to NOT attempt to display the notify command
table of data
Set $notify to true to attempt to display the notify command on
the single rig page
If your older version of cgminer returns an 'Invalid command'
coz it doesn't have notify - it just shows the error status table
---------
Default:
$checklastshare = true;
Set $checklastshare to true to do the following checks:
If a device's last share is 12x expected ago then display as an error
If a device's last share is 8x expected ago then display as a warning
If either of the above is true, also display the whole line highlighted
This assumes shares are 1 difficulty shares
Set $checklastshare to false to not do the above checks
'expected' is calculated from the device MH/s value
So for example, a device that hashes at 380MH/s should (on average)
find a share every 11.3s
If the last share was found more than 11.3 x 12 seconds (135.6s) ago,
it is considered an error and highlighted
If the last share was found more than 11.3 x 8 seconds (90.4s) ago,
it is considered a warning and highlighted
The default highlighting is very subtle
---------
Default:
$poolinputs = false;
Set $poolinputs to true to show the input fields for adding a pool
and changing the pool priorities on a single rig page
However, if $readonly is true, it will not display them
---------
Default:
$rigs = array('127.0.0.1:4028');
Set $rigs to an array of your cgminer rigs that are running
format: 'IP:Port' or 'Host:Port' or 'Host:Port:Name'
If you only have one rig, it will just show the detail of that rig
If you have more than one rig it will show a summary of all the rigs
with buttons to show the details of each rig -
the button contents will be 'Name' rather than rig number, if you
specify 'Name'
e.g. $rigs = array('127.0.0.1:4028','myrig.com:4028:Sugoi');
---------
Default:
$rigipsecurity = true;
Set $rigipsecurity to false to show the IP/Port of the rig
in the socket error messages and also show the full socket message
---------
Default:
$rigtotals = true;
$forcerigtotals = false;
Set $rigtotals to true to display totals on the single rig page
'false' means no totals (and ignores $forcerigtotals)
If $rigtotals is true, all data is also right aligned
With false, it's as before, left aligned
This option is just here to allow people to set it to false
if they prefer the old non-total display when viewing a single rig
Also, if there is only one line shown in any section, then no
total will be shown (to save screen space)
You can force it to always show rig totals on the single rig page,
even if there is only one line, by setting $forcerigtotals = true;
---------
Default:
$socksndtimeoutsec = 10;
$sockrcvtimeoutsec = 40;
The numbers are integer seconds
The defaults should be OK for most cases
However, the longer SND is, the longer you have to wait while
php hangs if the target cgminer isn't runnning or listening
RCV should only ever be relevant if cgminer has hung but the
API thread is still running, RCV would normally be >= SND
Feel free to increase SND if your network is very slow
or decrease RCV if that happens often to you
Also, on some windows PHP, apparently the $usec is ignored
(so usec can't be specified)
---------
Default:
$hidefields = array();
List of fields NOT to be displayed
You can use this to hide data you don't want to see or don't want
shown on a public web page
The list of sections are:
SUMMARY, POOL, PGA, GPU, NOTIFY, CONFIG, DEVDETAILS, DEVS
See the web page for the list of field names (the table headers)
It is an array of 'SECTION.Field Name' => 1
This example would hide the slightly more sensitive pool information:
Pool URL and pool username:
$hidefields = array('POOL.URL' => 1, 'POOL.User' => 1);
If you just want to hide the pool username:
$hidefields = array('POOL.User' => 1);
---------
Default:
$ignorerefresh = false;
$changerefresh = true;
$autorefresh = 0;
Auto-refresh of the page (in seconds) - integers only
$ignorerefresh = true/false always ignore refresh parameters
$changerefresh = true/false show buttons to change the value
$autorefresh = default value, 0 means dont auto-refresh
---------
Default:
$placebuttons = 'top';
Where to place the Refresh, Summary, Custom Pages, Quit, etc. buttons
Valid values are: 'top' 'bot' 'both'
anything else means don't show them - case sensitive
---------
Default:
$miner_font_family = 'verdana,arial,sans';
$miner_font_size = '13pt';
Change these to set the font and font size used on the web page
---------
Default:
$colouroverride = array();
Use this to change the web page colour scheme
See $colourtable in miner.php for the list of possible names to change
Simply put in $colouroverride, just the colours you wish to change
e.g. to change the colour of the header font and background
you could do the following:
$colouroverride = array(
'td.h color' => 'green',
'td.h background' => 'blue'
);
---------
Default:
$allowcustompages = true;
Should we allow custom pages?
(or just completely ignore them and don't display the buttons)
---------
OK this part is more complex: Custom Summary Pages
A custom summary page in an array of 'section' => array('FieldA','FieldB'...)
The section defines what data you want in the summary table and the Fields
define what data you want shown from that section
Standard sections are:
SUMMARY, POOL, PGA, GPU, NOTIFY, CONFIG, DEVDETAILS, DEVS, STATS, COIN
Fields are the names as shown on the headers on the normal pages
Fields can be 'name=new name' to display 'name' with a different heading
'new name'
There are also now joined sections:
SUMMARY+POOL, SUMMARY+DEVS, SUMMARY+CONFIG, DEVS+NOTIFY, DEVS+DEVDETAILS
SUMMARY+COIN
These sections are an SQL join of the two sections and the fields in them
are named section.field where section. is the section the field comes from
See the example further down
Also note:
- empty tables are not shown
- empty columns (e.g. an unknown field) are not shown
- missing field data shows as blank
- the field name '*' matches all fields except in joined sections
(useful for STATS and COIN)
There are 2 hard coded sections:
DATE - displays a date table like at the start of 'Summary'
RIGS - displays a rig table like at the start of 'Summary'
Each custom summary requires a second array, that can be empty, listing fields
to be totaled for each section
If there is no matching total data, no total will show
---------
Looking at the Mobile example:
$mobilepage = array(
'DATE' => null,
'RIGS' => null,
'SUMMARY' => array('Elapsed', 'MHS av', 'Found Blocks=Blks',
Accepted', 'Rejected=Rej', 'Utility'),
'DEVS+NOTIFY' => array('DEVS.Name=Name', 'DEVS.ID=ID', 'DEVS.Status=Status',
'DEVS.Temperature=Temp', 'DEVS.MHS av=MHS av',
'DEVS.Accepted=Accept', 'DEVS.Rejected=Rej',
'DEVS.Utility=Utility', 'NOTIFY.Last Not Well=Not Well'),
'POOL' => array('POOL', 'Status', 'Accepted', 'Rejected=Rej', 'Last Share Time'));
$mobilesum = array(
'SUMMARY' => array('MHS av', 'Found Blocks', 'Accepted', 'Rejected', 'Utility'),
'DEVS+NOTIFY' => array('DEVS.MHS av', 'DEVS.Accepted', 'DEVS.Rejected', 'DEVS.Utility'),
'POOL' => array('Accepted', 'Rejected'));
$customsummarypages = array('Mobile' => array($mobilepage, $mobilesum));
This will show 5 tables (according to $mobilepage)
Each table will have the chosen details for all the rigs specified in $rigs
DATE
A single box with the web server's current date and time
RIGS
A table of the rigs: description, time, versions etc
SUMMARY
This will use the API 'summary' command and show the selected fields:
Elapsed, MHS av, Found Blocks, Accepted, Rejected and Utility
However, 'Rejected=Rej' means that the header displayed for the 'Rejected'
field will be 'Rej', instead of 'Rejected' (to save space)
Same for 'Found Blocks=Blks' - to save space
DEVS+NOTIFY
This will list each of the devices on each rig and display the list of
fields as shown
It will also include the 'Last Not Well' field from the 'notify' command
so you know when the device was last not well
You will notice that you need to rename each field e.g. 'DEVS.Name=Name'
since each field name in the join between DEVS and NOTIFY is actually
section.fieldname, not just fieldname
The join code automatically adds 2 fields to each GPU device: 'Name' and 'ID'
They don't exist in the API 'devs' output but I can correctly calculate
them from the GPU device data
These two fields are used to join DEVS to NOTIFY i.e. find the NOTIFY
record that has the same Name and ID as the DEVS record and join them
POOL
This will use the API 'pools' command and show the selected fields:
POOL, Status, Accepted, Rejected, Last Share Time
Again, I renamed the 'Rejected' field using 'Rejected=Rej', to save space
$mobilesum lists the sections and fields that should have a total
You can't define them for 'DATE' or 'RIGS' since they are hard coded tables
The example given:
SUMMARY
Show a total at the bottom of the columns for:
MHS av, Found Blocks, Accepted, Rejected, Utility
Firstly note that you use the original name i.e. for 'Rejected=Rej'
you use 'Rejected', not 'Rej' and not 'Rejected=Rej'
Secondly note that it simply adds up the fields
If you ask for a total of a string field you will get the numerical
sum of the string data
DEVS+NOTIFY
Simply note in this join example that you must use the original field
names which are section.fieldname, not just fieldname
POOL
Show a total at the bottom of the columns for:
Accepted and Rejected
Again remember to use the original field name 'Rejected'
---------
With cgminer 2.10.2 and later, miner.php includes an extension to
the custom pages that allows you to apply SQL style commands to
the data: where, group, and having
As an example, miner.php includes a more complex custom page called 'Pools'
this includes the extension:
$poolsext = array(
'POOL+STATS' => array(
'where' => null,
'group' => array('POOL.URL', 'POOL.Has Stratum',
'POOL.Stratum Active', 'POOL.Has GBT'),
'calc' => array('POOL.Difficulty Accepted' => 'sum',
'POOL.Difficulty Rejected' => 'sum',
'STATS.Times Sent' => 'sum', 'STATS.Bytes Sent' => 'sum',
'STATS.Times Recv' => 'sum', 'STATS.Bytes Recv' => 'sum'),
'having' => array(array('STATS.Bytes Recv', '>', 0)))
);
This allows you to group records together from one or more rigs
In the example, you'll get each Pool (with the same URL+Stratum+GBT settings)
listed once for all rigs and a sum of each of the fields listed in 'calc'
'where' and 'having' are an array of fields and restrictions to apply
In the above example, it will only display the rows where it contains the
'STATS.Bytes Recv' field with a value greater than zero
If the row doesn't have the field, it will always be included
All restrictions must be true in order for the row to be included
Any restiction that is invalid or unknown is true
An empty array, or null, means there are no restrictions
A restriction is formatted as: array('Field', 'restriction', 'value')
Field is the simple field name as normally displayed, or SECTION.Field
if it is a joined section (as in this case 'POOL+STATS')
The list of restrictions are:
'set' - true if the row contains the 'Field' ('value' is not required or used)
'=', '<', '<=', '>', '>' - a numerical comparison
'eq', 'lt', 'le', 'gt', 'ge' - a case insensitive string comparison
You can have multiple restrictions on a 'Field' - but all must be true to
include the row containing the 'Field'
e.g. a number range between 0 and 10 would be:
array('STATS.Bytes Recv', '>', 0), array('STATS.Bytes Recv', '<', 10)
The difference between 'where' and 'having' is that 'where' is applied to the
data before grouping it and 'having' is applied to the data after grouping it
- otherwise they work the same
'group' lists the fields to group over and 'calc' lists the function to apply
to other fields that are not part of 'group'
You can only see fields listed in 'group' and 'calc'
A 'calc' is formatted as: 'Field' => 'function'
The current list of operations available for 'calc' are:
'sum', 'avg', 'min', 'max', 'lo', 'hi', 'any'
The first 4 are as expected - the numerical sum, average, minimum or maximum
'lo' is the first string of the list, sorted ignoring case
'hi' is the last string of the list, sorted ignoring case
'any' is effectively random: the field value in the first row of the grouped data
An unrecognised 'function' uses 'any'
