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: |
||||

The list of requests - a (*) means it requires privileged access - and replies are: |

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 |

This README contains extended details about FPGA mining with cgminer |

|
||||
Icarus |
||||
|
||||
There is a hidden option in cgminer when Icarus support is compiled in: |
||||
|
||||
--icarus-timing <arg> Set how the Icarus timing is calculated - one setting/value for all or comma separated |
||||
default[=N] Use the default Icarus hash time (2.6316ns) |
||||
short Calculate the hash time and stop adjusting it at ~315 difficulty 1 shares (~1hr) |
||||
long Re-calculate the hash time continuously |
||||
value[=N] Specify the hash time in nanoseconds (e.g. 2.6316) and abort time (e.g. 2.6316=80) |
||||
|
||||
Icarus timing is required for devices that do not exactly match a default Icarus Rev3 in |
||||
processing speed |
||||
If you have an Icarus Rev3 you should not normally need to use --icarus-timing since the |
||||
default values will maximise the MH/s and display it correctly |
||||
|
||||
Icarus timing is used to determine the number of hashes that have been checked when it aborts |
||||
a nonce range (including on a LongPoll) |
||||
It is also used to determine the elapsed time when it should abort a nonce range to avoid |
||||
letting the Icarus go idle, but also to safely maximise that time |
||||
|
||||
'short' or 'long' mode should only be used on a computer that has enough CPU available to run |
||||
cgminer without any CPU delays (an active desktop or swapping computer would not be stable enough) |
||||
Any CPU delays while calculating the hash time will affect the result |
||||
'short' mode only requires the computer to be stable until it has completed ~315 difficulty 1 shares |
||||
'long' mode requires it to always be stable to ensure accuracy, however, over time it continually |
||||
corrects itself |
||||
|
||||
When in 'short' or 'long' mode, it will report the hash time value each time it is re-calculated |
||||
In 'short' or 'long' mode, the scan abort time starts at 5 seconds and uses the default 2.6316ns |
||||
scan hash time, for the first 5 nonce's or one minute (whichever is longer) |
||||
|
||||
In 'default' or 'value' mode the 'constants' are calculated once at the start, based on the default |
||||
value or the value specified |
||||
The optional additional =N specifies to set the default abort at N 1/10ths of a second, not the |
||||
calculated value, which is 112 for 2.6316ns |
||||
|
||||
To determine the hash time value for a non Icarus Rev3 device or an Icarus Rev3 with a different |
||||
bitstream to the default one, use 'long' mode and give it at least a few hundred shares, or use |
||||
'short' mode and take note of the final hash time value (Hs) calculated |
||||
You can also use the RPC API 'stats' command to see the current hash time (Hs) at any time |
||||
|
||||
The Icarus code currently only works with a dual FPGA device that supports the same commands as |
||||
Icarus Rev3 requires and also is less than ~840MH/s and greater than 2MH/s |
||||
If a dual FPGA device does hash faster than ~840MH/s it should work correctly if you supply the |
||||
correct hash time nanoseconds value |
||||
|
||||
The timing code itself will affect the Icarus performance since it increases the delay after |
||||
work is completed or aborted until it starts again |
||||
The increase is, however, extremely small and the actual increase is reported with the |
||||
RPC API 'stats' command (a very slow CPU will make it more noticeable) |
||||
Using the 'short' mode will remove this delay after 'short' mode completes |
||||
The delay doesn't affect the calculation of the correct hash time |
||||
