Prometheus zookeeper exporter

Exports mntr zookeeper's stats in prometheus format.
zk_followers, zk_synced_followers and zk_pending_syncs metrics are available only on cluster leader.

Build

./build.sh script builds dabealu/zookeeper-exporter:latest docker image.
To build image with different name, pass it to build.sh as a first arg.

Usage

Usage of /usr/local/bin/zookeeper-exporter:
  -listen string
        address to listen on (default "0.0.0.0:8080")
  -location string
        metrics location (default "/metrics")
  -zk-host string
        zookeeper host (default "127.0.0.1")
  -zk-list string
        comma separated list of zk servers, i.e. '10.0.0.1:2181,10.0.0.2:2181,10.0.0.3:2181', this flag overrides --zk-host/port
  -zk-port string
        zookeeper port (default "2181")

An example docker-compose.yml can be used for management of clustered zookeeper + exporters:

# start zk cluster and exporters
docker-compose up -d

# get metrics of first exporter (second and third exporters are on 8082 and 8083 ports)
curl -s localhost:8081/metrics

# at 8084 port there's exporter which handles multiple zk hosts
curl -s localhost:8084/metrics

# shutdown containers
docker-compose down -v
