Issue/Introduction
After following the configuration steps found in Aria Operations for Logs, which are found at:
<FQDN>/log-sources/containers#item=1
you will consistently see the error:
Warning Failed 17s (x2 over 40s) kubelet Error: ImagePullBackOff
Environment
RedHat OpenShift Kubernetes Environment version 4.6 and above
Aria Operations for Logs 8.18.x.
Cause
Fluentd is an open source data collector for unified logging layer. It collects all the logs from the configured sources, processes/transforms them and then redirects them to appropriate endpoints.
Operations for Logs supports fluentd built-in http format natively. There's nothing specific that should be done in order to have fluentd send logs to Operations for Logs server other than setting the endpoint of HTTP plugin to <fqdn>/api/v2/events.
