Search Service Metrics

  • UNDER CONSTRUCTION
    +
    A list of the metrics provided by the Search Service.

    The following Search Service metrics can be queried by means of the REST APIs described in Getting Cluster Statistics.

    See also the metrics provided in Metrics for All Services; which are indeed for all Couchbase-Server services, and so support the Search Service.
