CEE Data Replication
The CEE replicates the data across all the three nodes (control plane, worker, and etcd). Also, the SMI Cluster Manager AIO model does not support the back up and recovery of operational data. Therefore, you must ensure the following to prevent the loss of monitoring data when a double node or triple node failure occurs:
-
Back up the CEE configuration for the Ops Center using the standard Ops Center backup and restore functionality.
-
Back up the Cluster Manager configuration for the Ops Center (remote cluster configuration) using the standard Ops Center backup and restore functionality.
-
For planned maintenance or unplanned outage in the SMI AIO mode, you can perform a cluster synchronization and restore the backed-up configuration.
-
Export the metrics (KPIs) from bulk stats regularly.
-
Gather Alerts in an external system.
