Ceph is a distributed storage system designed to provide excellent performance, reliability, and scalability. It achieves this by distributing data across multiple storage devices and ensuring data redundancy. As an open-source project, Ceph has become a popular choice for managing petabytes of data because of its self-healing and self-managing capabilities.
Monitoring Ceph clusters effectively is crucial to maintaining their optimal performance and ensuring data availability. Netdata offers a comprehensive Ceph monitoring tool that provides real-time insights into your Ceph infrastructure. By using Netdata’s collector for Ceph, you can access granular metrics for your entire Ceph cluster, including individual Pools and OSDs.
Monitoring Ceph is vital because it allows administrators to keep track of storage utilization, detect performance bottlenecks, and ensure the data integrity of the cluster. It also plays a critical role in disaster recovery, enabling quick identification of failed components or anomalies within the system.
Utilizing tools for monitoring Ceph, such as Netdata, provides several benefits. These include:
When you monitor Ceph with Netdata, it’s essential to focus on several key metrics to ensure the healthy status of your clusters:
A tabular representation of these metrics can offer an easy-to-understand view of your Ceph cluster’s performance:
| Metric Name | Description |
|---|---|
| Cluster Status | Overall status of the Ceph cluster |
| OSD Status | Up/in status of the OSDs |
| Pool Space Usage | Space utilization percentage of the pool |
Advanced techniques for monitoring Ceph involve correlating metrics across different domains, enabling predictive analysis, and setting automated responses to certain alerts. Using Netdata’s auto-recognition capabilities provides seamless monitoring with minimal setup.
Netdata’s user-friendly dashboards allow you to drill down into precise metrics such as IOPS, latency, and cluster usage, facilitating the identification of performance issues' root causes. By monitoring trends over time, you can predict potential issues before they escalate.

Ceph monitoring refers to the continuous observation and analysis of a Ceph cluster’s performance and health metrics to detect issues and optimize its functioning.
Ceph monitoring is important to maintain high availability and data integrity, identify bottlenecks and failures, and ensure that the system performs optimally.
In Ceph, monitors are responsible for maintaining maps of the cluster state, including OSDs, placement groups, and enforced policies, ensuring consistent and reliable data storage.
You can monitor Ceph in real-time using Netdata’s comprehensive dashboards that provide instant visualization of all critical metrics, helping you react promptly to any issues. You can access the Live Demo here.
