Prometheus metrics

5.10-SNAPSHOT 5.9 5.8 5.7 5.6 5.5 5.4 5.3 5.2 5.1 5.0

Management Center automatically reformats all Hazelcast cluster metrics for compatibility with Prometheus. In addition, Management Center updates a subset of metrics to align with Prometheus best practice recommendations. This makes it easier to construct complex queries, build dashboards, and work alongside metrics from other applications.

By default, Management Center exposes two versions of metrics based on Hazelcast’s JMX metrics system:

  • Version 1 (V1) metrics apply a basic transformation for compatibility with Prometheus:

    • Convert . to _

    • Add hz_ prefix

  • Version 2 (V2) metrics (currently in BETA) apply an advanced transformation for conformity with Prometheus naming conventions:

    • Use snake_case

    • Add hazelcast_ prefix

    • Update metric names where appropriate

    • Combine related metrics and add labels

    • Convert to recommended base units:

      • Time in seconds

      • Memory in bytes

      • Percentages as ratios (for example, 50% converts to 0.5)

    • Append units to metric names

    • Remove unit labels

    • Append _total to accumulated metrics

You can optionally change which set of metrics is exposed.

The following examples illustrate the differences between the V1 and V2 metrics.

  • Rename and remove unit label, add _total suffix:

    # V1
hz_map_queryCount{name="map-1",mc_member="127.0.0.1:5701",mc_cluster="Cluster-1",unit="COUNT",} 0.0 1737715903399
# V2
hazelcast_map_queries_total{name="map-1",mc_member="127.0.0.1:5701",mc_cluster="Cluster-1",} 0.0 1737715903399

  • Rename and append unit, remove unit label, convert value (1.7x1012 milliseconds to 1.7x109 seconds):

    # V1
hz_map_creationTime{name="map-1",mc_member="127.0.0.1:5701",mc_cluster="Cluster-1",unit="MS",} 1.737715861118E12 1737715903399
# V2
hazelcast_map_creation_timestamp_seconds{name="map-1",mc_member="127.0.0.1:5701",mc_cluster="Cluster-1",} 1.737715861118E9 1737715903399

  • Rename and append unit, remove unit label, add remove label:

    # V1
hz_map_totalMaxRemoveLatency{name="map-1",mc_member="127.0.0.1:5701",mc_cluster="Cluster-1",unit="MS",} 0.0 1737715903399
# V2
hazelcast_map_latency_max_seconds{name="map-1",mc_member="127.0.0.1:5701",mc_cluster="Cluster-1",operation="remove",} 0.0 1737715903399

  • Rename, append unit suffix and _total suffix, remove unit label, add remove label, convert value from milliseconds to seconds:

    # V1
hz_map_totalPutLatency{name="map-1",mc_member="127.0.0.1:5701",mc_cluster="Cluster-1",unit="MS",} 2019.0 1743601193973
# V2
hazelcast_map_latency_seconds_total{name="map-1",mc_member="127.0.0.1:5701",mc_cluster="Cluster-1",operation="put",} 2.019 1743601193973

Change the metrics version

To change which set of metrics is exposed to Prometheus, update the hazelcast.mc.prometheusExporter.printers system property:

  • V1: hazelcast.mc.prometheusExporter.printers=V1

  • V2: hazelcast.mc.prometheusExporter.printers=V2

  • V1 and V2 (default): hazelcast.mc.prometheusExporter.printers=V1,V2

See System properties and environment variables.

If you set the property to V2, Management Center will only expose the subset of metrics that have updated versions available.

Metrics list

The following table lists all V2 metrics with their V1 equivalents. The full list of Hazelcast metrics and descriptions is provided in the Hazelcast Platform documentation.

In some cases, several V1 metrics are combined into a single V2 metric differentiated by labels. For example, hazelcast_map_operations_total replaces hz_map_getCount and hz_map_setCount by adding operation="get" and operation="set" labels.
