Identify busy buckets, track cache miss ratios, and more. This Agent check collects metrics like:

• Hard disk and memory used by data
• Current connections
• Total objects
• Operations per second
• Disk write queue size

And many more.

The Couchbase check is included in the Datadog Agent package, so you don't need to install anything else on your Couchbase nodes.

1. Edit the couchbase.d/conf.yaml file, in the conf.d/ folder at the root of your Agent's configuration directory to start collecting your Couchbase performance data. See the sample couchbase.d/conf.yaml for all available configuration options.

init_config:

instances:
  - server: http://localhost:8091 # or wherever your Couchbase is listening
    #user: <your_username>
    #password: <your_password>

2. Restart the Agent to begin sending Couchbase metrics to Datadog.

Run the Agent's status subcommand and look for couchbase under the Checks section.

See metadata.csv for a list of metrics provided by this integration.

The Couchbase check emits an event to Datadog each time the cluster rebalances.

• couchbase.can_connect:

Returns Critical if the Agent cannot connect to Couchbase to collect metrics.

• couchbase.by_node.cluster_membership:

Returns Critical if the node failed over. Returns Warning if the node is added to the cluster but is waiting for a rebalance. Returns Ok otherwise.

• couchbase.by_node.health_status:

Returns Critical if the node is unhealthy. Returns Ok otherwise.
