Overview

Takes one or more samples of CPU usage and alerts if the average or maximum value exceeds specified thresholds. Can also focus on specific processes to alert if they are using too much CPU or memory. Includes a list of the top processes by CPU usage in every notification.

Use Cases

• Monitoring overall and per-core CPU Usage
• Keeping an eye on the top 10 CPU-using processes

Monitoring Options

This event monitor provides the following options:

Sample the CPU usage [#] times

Use this option to choose the number of times the CPU usage will be sampled.

Time between samples: [#] seconds

Use this option to control the number of seconds between each sample of the CPU usage.

Alert with [Info/Warning/Error/Critical] if the device cannot be contacted

Use this option to be alerted if the event monitor cannot contact the device.

Alert if the average CPU usage is greater than a specified percentage

Use this option to set alert levels for when the average CPU usage exceeds the percentages you specify.

Alert if the maximum CPU usage is greater than a specified percentage

Use this option to set alert levels for when the maximum CPU usage exceeds the percentages you specify.

Alert if the average CPU usage on an individual core is greater than a specified percentage

Use this option to be notified if the average CPU usage on any core is greater than the percentages you specify.

Alert if the maximum CPU usage on an individual core is greater than a specified percentage

Use this option to be alerted if the maximum CPU usage on an individual core exceeds the percentages you specify.

Include a list of the top 10 processes in every notification

Use this option to receive a list of the top 10 CPU-using processes in each notification generated by the event monitor.

Use WMI to retrieve the CPU usage

Use this option to retrieve CPU usage with WMI.
