Hi team,

Our new client has asked how we can check if a pod in a Kubernetes environment is running without a memory limit.

What capabilities does Instana offer for monitoring this situation?

Or any alerts can be configured for this scenario?

HI Sudhrsanam, 

considering that pods without memory limits will have value as 0, you can create a custom event, and select the below conditions :

Entity type: Kubernetes Pod

Metric : Memory Limits

Operator "="

count: 0

this will trigger an alert for all pods with no Memory limits.

Regards,

Hey,
you can identify running pods without a memory limit defined in Instana as follows : In Instana UI go to Platforms->Kubernetes
Choose the cluster you are interested in.
Choose the tab "Pods" and sort by Memory Limits
