Monitor Supervisor Instances with Site24x7 Plugins
Get the status of the supervisor server and processes and identify any slowdown caused by the instance.
The server piece of supervisor is called as supervisord. Thus, supervisord monitoring is critical to monitor the application processes managed by supervisor, its count, and the overall state of the server to keep a track of all the processes or identify the problematic ones.
This document details how to configure the supervisor plugin and the monitoring metrics for providing in-depth visibility into the performance, availability, and usage stats of supervisord servers.
Supervisor server monitoring metrics:
Site24x7 plugins offer insightful visualizations and timely alerts to ensure continued functioning of your supervisor instance.
Various out-of-the-box metrics we support are:
State of supervisord server
Of the many functions performed by the supervisord server, it starts the processes initiated by the client, restarts failed or exited processes and responds to commands from clients. Thus it is critical to know the status of the supervisord server to manage an application’s long-running processes
Total number of processes
Supervisor starts processes as sub processes and groups them. Thus, knowing the total_process_count managed by the supervisord server gives an idea as to how the supervisord managed processes are performing.
Number of stopped processes
stopped_process_count gives the total number of processes that are halted by the supervisord server
Number of running processes
The running_process_count is the number of processes that are currently active in the supervisord server
Number of processes with unknown status
The unknown_status_process_count is the number of processes which are neither running or stopped
How it works?
Log-in to your Site24x7 account. Sign up here if you don't have one
Download and install the latest version of Site24x7 Linux agent
Install the supervisor plugin extension
The agent will execute the supervisord plugin and push the data to the Site24x7 server
Site24X7 supervisord plugin uses Python's "supervisor" package to collect metrics
sudo pip install supervisor
sudo easy_install supervisor
Supervisor plugin installation:
Create a directory with the name "supervisord", under Site24x7 Linux agent plugin directory - /opt/site24x7/monagent/plugins/
sudo mkdir supervisord
Download the supervisord.py from our GitHub repository and place it under the "supervisord" directory
