Apache ZooKeeper collector
ZooKeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services.
This module monitors one or more ZooKeeper servers, depending on your configuration. It fetches metrics from ZooKeeper by using the mntr command.
Requirements
Zookeeper
with accessible client port- whitelisted
mntr
command
Metrics
All metrics have "zookeeper." prefix.
Metric | Scope | Dimensions | Units |
---|---|---|---|
requests | global | outstanding | requests |
requests_latency | global | min, avg, max | ms |
connections | global | alive | connections |
packets | global | received, sent | pps |
file_descriptor | global | open | file descriptors |
nodes | global | znode, ephemerals | nodes |
watches | global | watches | watches |
approximate_data_size | global | size | KiB |
server_state | global | state | state |
Configuration
Edit the go.d/zookeeper.conf
configuration file using edit-config
from the
Netdata config directory, which is typically at /etc/netdata
.
cd /etc/netdata # Replace this path with your Netdata config directory
sudo ./edit-config go.d/zookeeper.conf
Needs only address
to server's client port. Here is an example for 2 servers:
jobs:
- name: local
address: 127.0.0.1:2181
- name: remote
address: 203.0.113.10:2182
For all available options, please see the module configuration file.
Troubleshooting
To troubleshoot issues with the zookeeper
collector, run the go.d.plugin
with the debug option enabled. The output
should give you clues as to why the collector isn't working.
Navigate to the
plugins.d
directory, usually at/usr/libexec/netdata/plugins.d/
. If that's not the case on your system, opennetdata.conf
and look for theplugins
setting under[directories]
.cd /usr/libexec/netdata/plugins.d/
Switch to the
netdata
user.sudo -u netdata -s
Run the
go.d.plugin
to debug the collector:./go.d.plugin -d -m zookeeper
