how to send alert when a container in a container group enters the terminated state?

Question

I have i group of containers running in a container group in (Azure container Instances), I was able to set up Azure application insights in such a way that it monitors the front-end point of the app, it has been monitoring it successfully, but recently one of the containers in the container group started failing which had nothing to do with the endpoint that is being monitored by application insights and i was not able to know about that event.

is there a way to monitor the status of specific containers in a container group, such that when it changes we get an alert about the change in status of that particular container in the container group. ?

please help thanks.

Hello Joshua Igoni

When a container gets in Terminated state, it usually means it was killed.

To create an alert you should first enable logging and events collected with Azure Monitor Log Analytics Workspace and then, use the following query to create a log based alert:

ContainerEvent_CL
| where Message contains "Killing" | where TimeGenerated > ago(5m) | project TimeGenerated,ContainerGroup_s,Message

This will query when a container gets "Killing" and based on the query results you can set the alert.
