Hi,
I used controller v4.2 to monitor python application, which running by gunicorn : http://gunicorn.org/
I followed the appdynamic instruction : https://www.appdynamics.com/university/python-monitoring-tutorials/
but nothing happend. The agent couldnt connect to the controller. I went though the proxy log and got this :
[main] 14 Nov 2016 13:56:03,150 INFO com.singularity.proxyControl.ProxyControlEntryPoint - ProxyControl - init
[main] 14 Nov 2016 13:56:03,150 INFO com.singularity.proxyControl.ProxyControlEntryPoint - comm dir set to: /tmp/appd/run/comm
[main] 14 Nov 2016 13:56:03,175 INFO com.singularity.proxyControl.ZeroMQControlServer - ipcNodeBaseDir dir set to: /tmp/appd/run/comm/proxy-732969647002964696
[main] 14 Nov 2016 13:56:03,175 INFO com.singularity.proxyControl.ZeroMQControlServer - ZeroMQControlServer - init
[main] 14 Nov 2016 13:56:03,231 INFO com.singularity.proxyControl.ZeroMQControlServer - ControlReqRouterSocket started at:ipc:///tmp/appd/run/comm/0
[main] 14 Nov 2016 13:56:03,498 INFO com.singularity.proxyControl.ProxyControlEntryPoint - ProxyControl - init completed
[main] 14 Nov 2016 13:56:03,499 INFO com.singularity.proxyControl.ProxyControlEntryPoint - Should register node at startup:false
the python_node_<pid>.log was empty, while the watchdog.log said, proxy was started with pid
that's all log I got, the application was running fine but i have no idea why the controller didnt get any data.
