Docker container filesystem usage monitoring

    Hi Community,

     

    Actually I'm using CA APM agentless Docker container monitor field pack with good results .

     

    But I like to monitor filesystems % usage (inside of containers).

     

    It's possible ? 

     

    I don't like use epagent because I have a lot of containers running (some containers with elastic definitions).

     

    Regards

    Hi Aldo:

    From my reading of the internal docs, I do not see this capability at this time. However, I will ask internally for some one more knowledgeable to respond.Hopefully, I can get you a response.

    Thanks

    Aldo,

    The Docker monitoring that you're using is monitoring the Docker platform, and therefore can only see metrics at that level.  Filesystem utilization is a concept that is specific to the operating systems of the individual containers, so you can only get it by running commands in the container.

     

    The good news is that Docker does provide a way to run commands in the container: docker exec.

    You could use that to write a script that runs 'df' or something on each running container.
