Troubleshooting replication queues

As the ingest rate increased, the number of ingests pending and the number of ILM evaluations pending increased because the LDR and CMS services could not keep up with the increased ingest rate.

Trends suggest that something must have changed in the StorageGRID Webscale deployment’s environment to account for the increased number of objects being ingested into the system. Did new client applications start ingesting objects? Is legacy data being migrated to the StorageGRID Webscale system? Data migration can cause queues to build up to a point where operations are disrupted. For guidelines on how to manage data migration, see the Administrator Guide.

Queues should be resolved early by a prompt response to alarms with a severity of Notice. The following figure shows where ingest and replication queues are likely to build up and where alarms are likely to be triggered.
