above are the OtelCollector pod logs
the above is error am facing since yesterday
s
This happens when the collector process receives a 
SIGINT
or 
SIGTERM
signals.
s
i have increased the readiness and livenessProbe values to below initialDelaySeconds: 20 periodSeconds: 10 timeoutSeconds: 10 failureThreshold: 8 successThreshold: 1 still pods are getting into CrashLoop Backoff state
All the pods are Crashing sometimes suddenly, resources are available still pods are getting failed. What could be the reason @Srikanth Chekuri?
is this because of Otel-collector image tag? Should i keep the image tag fized?
s
What image tag are you using? What are the error logs? It would help if you could share more context
s
Copy code
warn	k8sattributesprocessor@v0.88.0/processor.go:54	k8s.pod.start_time value will be changed to use RFC3339 format in v0.83.0. see <https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/24016> for more information. enable feature-gate k8sattr.rfc3339 to opt into this change.	{"kind": "processor", "name": "k8sattributes", "pipeline": "metrics/internal"}

The above are the warnings i could see in the pod logs
s
The warnings are not harmful. I am not sure why they crash. I believe it's specific to your environment.
s
first pod state is getting into OOMKILLED and into CrashloopBackoff. is this because of am giving the limit for the memory for otell collector pod?
s
How much memory limit did you set?
s
Hi @Srikanth Chekuri, issue was with the memory limit for the otel collector pod. its fixed. Thanks
