Pulsar exposes the following metrics in Prometheus format. You can monitor your clusters with those metrics.
The following types of metrics are available:
_bucket
suffix is the number of observations within a histogram bucket, configured with parameter {le="<upper inclusive bound>"}
. The _count
suffix is the number of observations, shown as a time series and behaves like a counter. The _sum
suffix is the sum of observed values, also shown as a time series and behaves like a counter. These suffixes are together denoted by _*
in this doc.The ZooKeeper metrics are exposed under “/metrics” at port 8000
. You can use a different port by configuring the metricsProvider.httpPort
in conf/zookeeper.conf.
ZooKeeper provides a New Metrics System since 3.6.0, more detailed metrics can refer ZooKeeper Monitor Guide.
The BookKeeper metrics are exposed under “/metrics” at port 8000
