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.

Requirements

• Zookeeper with accessible client port
• whitelisted mntr command

Charts

It produces the following charts:

• Outstanding Requests in requests
• Requests Latency in ms
• Alive Connections in connections
• Packets in pps
• Open File Descriptors in file descriptors
• Number of Nodes in nodes
• Number of Watches in watches
• Approximate Data Tree Size in KiB
• Server State in state

Configuration

Edit the go.d/zookeeper.conf configuration file using edit-config from the your agent's 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

Check the module debug output. Run the following command as netdata user:

./go.d.plugin -d -m zookeeper
