Pulsar metrics
Pulsar exposes the following metrics in Prometheus format. You can monitor your clusters with those metrics.
The following types of metrics are available:
- Counter: a cumulative metric that represents a single monotonically increasing counter. The value increases by default. You can reset the value to zero or restart your cluster.
- Gauge: a metric that represents a single numerical value that can arbitrarily go up and down.
- Histogram: a histogram samples observations (usually things like request durations or response sizes) and counts them in configurable buckets. The
_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. - Summary: similar to a histogram, a summary samples observations (usually things like request durations and response sizes). While it also provides a total count of observations and a sum of all observed values, it calculates configurable quantiles over a sliding time window.
ZooKeeper
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. For more detailed metrics, refer to the ZooKeeper Monitor Guide.
BookKeeper
The BookKeeper metrics are exposed under "/metrics" at port 8000
. You can change the port by updating prometheusStatsHttpPort
in the bookkeeper.conf
configuration file.
