CPU Performance monitoring is accomplished via SNMP and WMI.
SNMP-based CPU Performance Monitoring
AggreGate Network Manager can collect CPU load data via SNMP and process it.
|
According to RFC 1514 CPU load is the average, over the last minute, of the percentage of time that this processor was not idle. |
AggreGate Network Manager uses hrProcessorLoad SNMP variable to get the average CPU load. The variable is part of hrProcessorTable, providing separate data for all host's processors.
The SNMP-based CPU Load monitoring tools include:
| • | CPU Load Top 10 Auto Run action that shows 10 devices with the highest CPU load |
|
The CPU Load chart can be created and configured using Setup Monitoring Profile action -- see CPU group in Setup Monitoring Profile Action. |
System administrators can create other tools (e.g. alerts, widgets, etc.) for interpreting data provided by hrProcessorTable SNMP variable.
|
CPU utilization on VMware ESX servers by particular virtual machines can be monitored using Virtual Machine CPU Load alert and Virtual Machine CPU Utilization chart. |
WMI-base CPU Performance Monitoring
AggreGate Network Manager can use WMI to obtain CPU performance data as instances of Win32_PerfFormattedData_Counters_ProcessorInformation. The WMI-based CPU performance monitoring tools include CPU Activity alert.
