With the IMF, VCS supports intelligent resource monitoring in addition to the poll-based monitoring. IMF is an extension to the VCS agent framework. Many VCS agents use IMF for monitoring resources. You can enable and disable the IMF functionality of the VCS agents as needed. However, IMF is enabled by default for all agents that support IMF.
The benefits of intelligent monitoring over poll-based monitoring are as follows:
Provides faster notification of resource state changes.
Reduces VCS system utilization due to reduced monitor function footprint, which enables VCS to effectively monitor a large number of resources.
