Cluster Manager Metrics

    A list of the metrics provided by the Cluster Manager.

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

    Histograms

    Note that each histogram metric will generate three time series, with the following suffixes:

    • _count

    • _sum

    • _bucket

    Please refer to Prometheus Histograms and Summaries for more information.

    Tip

    • The x.y.z badge shows the Couchbase Server version the metric was added in.

    • The type / unit badge shows shows the Prometheus type and unit (if present).
