ZooKeeper Monitoring
What Is ZooKeeper?
ZooKeeper is a high-performance coordination service for distributed applications, developed as a project of the Apache Software Foundation. It provides a reliable, centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. Whether you’re using it for service discovery or to build resilient distributed locks, understanding its operations can ensure high availability and performance of your applications.
Monitoring ZooKeeper With Netdata
Monitoring ZooKeeper effectively is crucial for ensuring the health and performance of your distributed systems. The Netdata agent makes this process straightforward by automatically detecting ZooKeeper instances running on known TCP sockets such as 127.0.0.1:2181. To get started, you’ll need to add mntr to ZooKeeper’s 4lw.commands.whitelist. Once set up, Netdata provides real-time monitoring capabilities, making it the ideal ZooKeeper monitoring tool.
Why Is ZooKeeper Monitoring Important?
Monitoring ZooKeeper is essential for maintaining the health of distributed systems. It ensures that your coordination service is running smoothly and helps in diagnosing potential problems before they escalate into significant outages. By using tools for monitoring ZooKeeper, you can track metrics that reveal insights about load, response time, queue sizes, and other performance data.

Understanding ZooKeeper Performance Metrics
These are some of the key metrics to monitor with Netdata’s ZooKeeper monitoring tool:
- Outstanding Requests: The number of requests that have been queued. A high number might indicate a bottleneck.
- Requests Latency: Time taken for requests. Monitoring min, avg, and max latencies helps in understanding responsiveness.
- Alive Connections: The number of currently active connections.
- Stale Requests: Indicates requests that are not being processed in a timely manner.
- Auth Fails: The number of failed authentication attempts.
- Server State: Displays the state of ZooKeeper’s server (Leader, Follower, Observer, Standalone).
| Metric Name | Description |
|---|---|
| Outstanding Requests | Number of queued requests |
| Requests Latency | Minimum, average, maximum request time |
| Alive Connections | Number of active connections |
| Stale Requests | Requests delayed or not processed |
| Auth Fails | Failed authentication attempts |
| Server State | Current state of the server |
Advanced ZooKeeper Performance Monitoring Techniques
To delve deeper into the performance issues, consider using advanced monitoring techniques like:
- Analyzing trends over time to predict failures before they happen.
- Setting alerts on critical metrics like server state changes or high latency.
Diagnose Root Causes Or Performance Issues Using Key ZooKeeper Statistics & Metrics
By understanding your ZooKeeper metrics, you can diagnose the root causes of performance issues, such as overloaded nodes, authentication failures, or network problems. Tools like Netdata make this diagnostic process more efficient and actionable by providing visualization and alerting capabilities.
