Troubleshooting Namespace Issues In Alerts with Otel+Signoz

TLDR Ayushman had a query about retrieving their kubectl pod's namespace in alerts using otel+signoz. Prashant and Srikanth gave steps, but found that Ayushman's applications might not be sending the necessary attributes.

Hi there 👋

You can use k8s namespace in alerts using the following:

{{ .Labels.k8s_namespace_name }}

i checked this and grouped by this but this is always "monitoring" where my signoz is deployed and not the services.

I also saw "service_namespace" and that is always "default" where as I have no services in default namespace.

In both cases, it is most likely your applications are not sending the k8s.namespace.name , service.namespace attributes.
