SCOM Monitor types - Create Unit Monitor for Monitor Windows Service availability in SCOM 2019

 

SCOM Monitoring

KPI in SCOM – There are four types of KPI in SCOM Processor, Memory, Days and Network.

Using these KPI you can understand or you can find out the overall health of the server.

What is Monitor in SCOM -:  Basically monitor works on state based like healthy, warning and critical and measures the health of some aspects of managed objects.

Unit Monitoring -: So that's basically the most common monitor which is being used in SCOM by your admins to create, monitoring for any specific object or any specific entity.

When we refer to monitors, we usually refer to unit monitors.

Only a unit monitor also measures some aspects of an application.

Dependency rollup monitors -: Dependency monitors let the health of one object be affected 

by the health of another object. This allows for health rollup between specific related instances 

of different classes.

Aggregate rollup Monitor-: Aggregate monitors group multiple monitors to provide a single 

Health aggregated health state. This provides an organization to all of the monitors targeted at 

a particular class and provides a consolidated health state for specific categories of operation.
