Performance Metrics of a Nutanix Cluster Monitor
Stay on top of your Nutanix cluster performance by monitoring key performance metrics of your Nutanix cluster's storage controller, disk, and content cache—all from a single console. Monitor your Nutanix cluster environment using Site24x7 On-Premise Poller. Add a cluster to monitor and get started.
By monitoring a Nutanix cluster, you can:
- View different performance metrics.
- Add a threshold and availability profile to declare a specific resource as critical or down.
- Analyze critical performance issues using reports.
Interpret Nutanix cluster performance metrics
View different performance graphs from the Disk, Content Cache, and Storage Controller tabs.
- Summary: Lists key CPU, memory, and storage stats along with cluster configuration, settings, and hardware summary details.
- Disk: Displays graphs of the various I/O operations, latencies, and data transfers.
- Content Cache: Shows the number of hits and lookups, and the different types of memory used.
- Storage Controller: Shows different I/O operations, latencies, and data transferred from the storage controller.
