VM Performance Monitors

The VM performance monitors allow you to monitor and alert on specific VM-related components: datacenters, clusters, resources pools, and vApps (VMware only); and VM hosts, instances, and snapshots.

The metrics collected through VM servers can be used by Uptime Infrastructure Monitor through Sync or vSync, and subsequently used to trigger Uptime Infrastructure Monitor’s own alerts and actions, allowing you to integrate both your virtual-managed and non-virtual resources.

These performance monitors can answer questions such as the following:

Is the CPU usage of VMs in a vApp, resource pool, cluster, or datacenter passing an acceptable level?
Is the memory consumed by VMs in a vApp, resource pool, cluster, or datacenter passing an acceptable level?
Is the number of ESX servers that are a part of the cluster or datacenter exceeding an acceptable number and threatening performance?

Datacenter and Cluster Performance (VMware only)

The Datacenter Performance and Cluster Performance monitors can trigger alerts on metrics collected through vSync.

Datacenter Performance and Cluster Performance Monitor Metrics

The following VM metric types for datacenter or cluster performance can be used to configure thresholds in Uptime Infrastructure Monitor:

Time Interval	A positive integer indicating the number of minutes’ worth of performance data samples to average, then compare against threshold definitions (default: 30).
Number of Running VMs: warning threshold and critical threshold	Warning- and critical-level thresholds can be set, using positive integers, for the average number of VMs powered on during the time interval.
Number of Running Hosts: warning threshold and critical threshold	Warning- and critical-level thresholds can be set, using positive integers, for the average number of vSphere ESX servers powered on during the time interval.
CPU Consumed: warning threshold and critical threshold	Warning- and critical-level thresholds can be set, using positive integers, for the total percentage of CPU cycles consumed by VMs belonging to this datacenter or cluster.
Memory Consumed: warning threshold and critical threshold	Warning- and critical-level thresholds can be set, using positive integers, for the total percentage of memory consumed by VMs belonging to this datacenter or cluster.

VM Performance

The VM Host Performance Check and VM Instance Performance monitors can trigger alerts on metrics collected through Sync or vSync.

VM Host Performance Check Monitor and VM Instance Performance Monitor Metrics

The following VM metric types for VM host and instance performance can be used to configure thresholds in Uptime Infrastructure Monitor:

Time Interval A positive integer indicating the number of minutes' worth of data samples to average, then compare against threshold definitions (default: 15).

CPU Value

Warning- and critical-level thresholds can be set, using positive integers, for a specific CPU-related value pertaining to a VM host or instance:

Usage (%): the percentage of total available CPU that was used
Usage (MHz): the average amount of CPU used, in MHz
Ready Time (%): the percentage of the interval that the VM was ready to process, but was not scheduled CPU time by the host
Wait Time (%): the percentage of the interval that the VM had scheduled CPU time, but gave nothing to process

Info
If the virtual machine's allocated CPU resources in the VMware vSphere Client is set to its default Unlimited value, the Usage (%) metric in Uptime Infrastructure Monitor will be based on the total available CPU for the host.

Memory Value

Warning- and critical-level thresholds can be set, using positive integers, for a specific memory-related value pertaining to a VM host or instance:

Usage (%): the percentage of total configured/available memory
Memory Consumed (MB): the amount of memory consumed

- for the instance (VM Instance Performance)
- across all virtual machines on this host (VM Host Performance Check)
Zero Memory (KB): Memory allocated to virtual machines that only contains zeros (VM Host Performance Check)
