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.
