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
Note: starting from zookeeper v3.4.10 it's required to have mntr command whitelisted (details: 4lw.commands.whitelist).
Usage of zookeeper-exporter:
-listen string
address to listen on (default "0.0.0.0:9141")
-location string
metrics location (default "/metrics")
-timeout int
timeout for connection to zk servers, in seconds (default 120)
-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
