Health alerts
Understand the health alerts generated by the Network Observability Operator, which trigger banners when conditions like Loki ingestion errors, zero flow ingestion, or dropped eBPF flows occur.
A health alert banner that directs you to the dashboard can appear on the Network Traffic and Home pages if an alert is triggered. Alerts are generated in the following cases:
-
The
NetObservLokiErroralert occurs if theflowlogs-pipelineworkload is dropping flows because of Loki errors, such as if the Loki ingestion rate limit has been reached. -
The
NetObservNoFlowsalert occurs if no flows are ingested for a certain amount of time. -
The
NetObservFlowsDroppedalert occurs if the Network Observability eBPF agent hashmap table is full, and the eBPF agent processes flows with degraded performance, or when the capacity limiter is triggered.
