Performance Metrics of a Nutanix VM Monitor
Gain a deep understanding of various metrics that affect the performance and health of your Nutanix virtual machines (VMs) with information on their storage containers, virtual disks, and virtual network interface controllers (NICs) to identify and troubleshoot issues. Simply add add an On-Premise Poller, a VM to monitor, and get started.
With Nutanix VM monitoring, you can:
- View different performance metrics.
- Add a threshold and availability profile to declare a specific resource as critical or down.
- Configure thresholds at the child-level.
- Analyze critical performance issues using reports.
Interpret Nutanix VM performance metrics
View individual component-wise performance from different tabs.
- Summary: Lists key CPU, memory, and disk stats along with VM configuration, settings, and hardware summary details.
- Storage Containers: Displays graphs for the top containers by space, data transfer, and latency of the storage controller along with basic details.
- Virtual Disks: Displays the top virtual disks by I/O operations along with child-level controller metrics.
- Virtual NICs: Shows various graphs on data received and transferred, including child-level Rx and Tx metrics.
