Few months ago I installed metricbeat in K8S cluster and everything was working fine. All of a sudden after 1-2 months I get error:
Temporary bulk send failure - Drop batch
INFO [publisher] pipeline/retry.go:223 done INFO [publisher] pipeline/retry.go:159 Drop batch ERROR [publisher_pipeline_output] pipeline/output.go:180 failed to publish events: temporary bulk send failure INFO [publisher_pipeline_output] pipeline/output.go:143 INFO [publisher] pipeline/retry.go:213 retryer: send wait signal to consumer
Why do I get this error and how can I fix this error without uninstalling everything?
PS: Metricbeat is running on about 40 clusters.
