Apache ZooKeeper monitoring with Netdata

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, open netdata.conf and look for the plugins 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
```
