The agents monitor the environment by running periodic tests. The outputs of the tests are called measurements. A measurement determines the state of a network / system / application / service element of the target environment. For example, a Process test reports the following measurements:
- Number of processes of a specific type executing on a system.
- The CPU utilization for these processes
- The memory utilization for these processes
Agents use different approaches for testing the target environments. Based on the monitoring approach employed and where they are installed, agents are classified as follows:
To know the details on the types, mechanisms used to collect performance metrics and installation procedure of agents have been elaborately discussed in
