Hey there,

It’s hard to say what the issue with the script is. Exit code 127 typically indicates that the script can’t be found, so I’m a bit confused because the check output doesn’t jive with the exit code. It would help to see the check definition and the script as the screenshots don’t really help in diagnosing the issue.

As an aside, is there a reason that you’re using a custom memory check instead of using some of the existing plugins that do just this?

let me explain the scenario, i had installed sensu to monitor the 2 azure vms and i have 3 checks on every vm . for 2 checks i had used the built in plugin in sensu bonsai . and for 3rd check i,e for memory usage i used sensu plugin but the output was in the bytes format. i was not able to convert to human readble format. so i thought of writing own script and executing so same thing i wrote in shell scripted and kept in /tmp/ folder in every containers. but all containers script is running properly. only in particular vm i am getting error like this… NOTE : i am running sensu backend and agents as docker containers.
