cgminer-monitor

Simple monitor script for cgminer in python.
Console display, http server, email alerts. No additional modules required.

Tested with python 2.7.2 and cgminer 3.2.0.

usage: cgminer-monitor.py [command] [parameter]


Monitor mode
cgminer-monitor.py
 - Monitors cgminer by checking a few critical values
 - Emails if something is wrong
 - Restarts cgminer if the GPU is sick or dead
 - Runs a dead simple http server that only serves a page with the results of the monitor (identical to the console output with a nice display)
 - Monitors MMFCE pools and display the current balance in their currencies
 - Could support multi-gpus very easily (see comment in the code)
 - CTRL+C to stop everything








Command mode
cgminer-monitor.py somecommand someoptionalparameter
 - Ouputs the results returned by cgminer miner and exits
 - Examples:
    - cgminer-monitor.py summary
    - cgminer-monitor.py gpu 0
    - See cgminer's API-README for all available commands

Notes
I know there are a bunch of watchers, web interfaces and all but they are far too advanced for my light mining. I didn't want to have to run somone's .exe or have to compile it myself, or install apache/php, etc.
I just wanted the simplest thing so I made this single python script (about 200 lines without the comments) to do everything listed above. There is no install or anything, just set a couple of config values at the top and run it.

It only supports 1 GPU (because I've only one :/) but that should be as simple as adding a for loop and changing a couple of indexes to support multi gpus.

Updates

06/22/2013:
Monitors MMFCE pools + minor improvements

• Monitors MMFCE pools and display the current balance in their currencies (web page only)
• Display the current pool URL
• Don't send a warning email in the first 10 seconds (hashrate takes a bit to get stable)
• Use a smaller font for the web page
• Ignore requests on /favicon.ico that most browsers send
• Faster shutdown with CTRL+C (within 1 second)

New update - 06/22/2013:

Monitors MMFCE pools + minor improvements

• Monitors MMFCE pools and display the current balance in their currencies (web page only)
• Display the current pool URL
• Don't send a warning email in the first 10 seconds (hashrate takes a bit to get stable)
• Use a smaller font for the web page
• Ignore requests on /favicon.ico that most browsers send
• Faster shutdown with CTRL+C (within 1 second)

I kept the spirit of the script intact while making this update. There is still no additional dependencies and still just 1 file to run.
Updated screenshots on first post.

As long as you run cgminer and the API has not changed the script should just work with it.

It should work, the API looks the same: https://github.com/luke-jr/bfgminer/blob/bfgminer/README.RPC
The monitor is only using the following commands: coin, pools, gpu, summary, stats, restart and they're all in bfgminer's page.

Your cgminer is not listening on localhost on the port 4028. The monitor can't connect to it.

You can either launch cgminer with default API settings (listening interface/port), or you can edit these 2 lines at the top of cgminer-monitor.py.
