Issue/Introduction

Data ingestion charts show a broken dotted line for the ~collector.*points.reported metrics. Duration typically lasts for approximately 2 to 5 minutes.

Resolution

The `~collector.points.*` metrics are synthetic counter metrics provided by Wavefront to monitor the ingestion rate.

It is expected behavior to see the `~collector.points.*` metric reporting a gap period of 2 to 5 minutes then resume reporting at the previous rate when there is a failover from one mirror to another mirror.

• These failover events can be manually triggered by the operations team during routine maintenance or upgrades to the cluster.
• Wavefront also has built in logic that detects the optimal healthy mirror based on many infrastructure metrics and switches the cluster to the healthiest mirror when necessary.

There is no data loss or blocked ingestion, and no impact to the performance of the Wavefront cluster during this time. The break in reporting is merely due to an internal metrics aggregator feature that aggregates the data points across all collectors.
