This README contains details about the cgminer RPC API
|
|
|
|
|
|
|
|
|
|
|
|
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.
|
|
|
|
Without it those commands return an access denied status.
|
|
|
|
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
|
|
|
|
|
|
|
|
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 1.9:

|
|
|
|
|
|
|
|
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
|
|
|
|
|
|
|
|
When you enable, disable or restart a GPU or PGA, you will also get Thread messages
|
|
|
|
in the cgminer status window
|
|
|
|
|
|
|
|
When you switch to a different pool to the current one, 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) you will also get messages showing
|
|
|
|
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
|
|
|
|
Read the top of the file (miner.php) for details of how to tune the display
|
|
|
|
and also to use the option to display a multi-rig summary
