Resource utilization in poll-based monitoring and intelligent monitoring

Description

Resource utilization in poll-based monitoring and intelligent monitoring

Poll-based monitoring can consume a fairly large percentage of system resources such as CPU and memory on systems with a huge number of resources. High CPU usage not only affects the performance of running applications, but also places a limit on the number of resources that an agent can monitor efficiently. With IMF-based monitoring, you can either eliminate poll-based monitoring completely or reduce its frequency. Such reduction in monitor footprint makes more system resources available for other applications to consume.

The following graphics show that CPU utilization reduces when you enable IMF. CPU utilization for the following scenarios are shown:

  • Intelligent monitoring is on.

  • Intelligent monitoring is off.

  • Both Intelligent monitoring and poll-based monitoring are on.
