With the introduction of agent-based monitoring in OpManager, users can now install a lightweight piece of software called an "agent" in their network devices such as Windows servers to aid OpManager with monitoring your devices. The agent takes over all polling actions related to that device from OpManager, allowing your OpManager server to function more efficiently. For smooth functioning of OpManager without load configuration changes, it is recommended that the agent be installed on not more than 500 devices.
