a supervisor rpc extension for obtaining the hosts system and process information.
- Python 2.7+
- supervisor 3.0+
- psutil
- I use supervisor on many of my servers for control and monitoring and I needed a way to interrogate the sevrers for top, df and ps type information. Rather than have my own status server I've extended supervisor's XML-RPC api to offer two new functions:
- sysinfo.ps which returns a dictionary keyed by pid of the output of ps aux.
- sysinfo.sysInfo which reruns cpu, memory and disk usage information.
Both functions return json strings. I do this as a work around the 32-bit int limitation of the XML-RPC standard.
Use the usual ways:
pip install git+https://github.com/thanos/supervisor-sysinfo.git
In your supervisor.conf file setup:
[inet_http_server] port = *:9002 username = very_safe password = very_safe
Uncomment:
[rpcinterface:supervisor] supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
Add:
[rpcinterface:sysinfo]
supervisor.rpcinterface_factory = supervisor_sysinfo.rpcinterface:make_sysinfo_rpcinterface
[eventlistener:monitor]
command=supervisor_monitor http://some_end_point.com:7000/monitor
events= TICK_60
You can look at the test code but effectively you need to do this:
import xmlrpclib,pprint, json
rpc_proxy = xmlrpclib.ServerProxy('http://very_safe:[email protected]:9002')
ps_list = json.loads(rpc_proxy.sysinfo.ps())
pprint.pprint(ps_list)
sysInfo = json.loads(rpc_proxy.sysinfo.sysInfo())
pprint.pprint(sysInfo)
To run the all tests run:
