Couchbase Complete Snapshot

Couchbase complete snapshot is responsible for collecting metrics from a single cluster and evaluating the results according to the production best practices

Production Check List

Cluster Health Check List

Architecture

• MDS model should be applied for better scaling and stability.
• Couchbase version should be the same among the nodes in the cluster.

Buckets

• Couchbase bucket should have at least 1 replica.
• Couchbase bucket should have 1024 primary vbuckets.
• A couchbase bucket's resident ratio needs to be high(It depends according to your bucket size, memory size etc..)

Settings

• Auto failover configuration needs to be enabled.
• Email alerts needs to be enabled.

XDCR Health Check List

• XDCR cluster versions should be the with the production cluster.
