Performance Metrics of a Nutanix Host monitor
Stay on top of your Nutanix host's health and performance by monitoring key performance metrics of its hypervisor, CPU, memory, disk, and content cache—all from a single console. Monitor your Nutanix host environment using Site24x7 On-Premise Poller. Add a host to get started with monitoring.
By monitoring a Nutanix host, 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 host performance metrics
Different tabs display different metrics, grouped by category.
- Summary: Lists key CPU, memory, and storage stats along with host configuration and hardware summary details.
- I/O Operation: Displays various I/O operations from the disk, hypervisor, and storage controller as graphs.
- Bandwidth: Displays data transfer information as graphs from the disk, hypervisor, and storage controller.
- Latency: Shows the read, write, and average latencies of the disk, hypervisor, and storage controller.
- Content Cache: Shows the number of hits and lookups, and the different types of memory used.
