What is agentless monitoring?
A. Though managing systems and services is most efficient and scaleable with agents, there are always situations where agent bits can not be installed on a certain population of managed devices. MOM 2005 provides the ability to manage devices agentlessly, which from the operator’s point of view appears like agent managed devices in most respects. The devices appear in all MOM views and management packs can be targeted to them. Heartbeat for the devices is simulated by the MOM server. There are some limitations to be aware of: • Security: Since the MOM server collects instrumented data remotely from these devices, they cannot be across a firewall and the MOM Server action account needs to run with administrator privileges on the managed devices. • Scale: Since the MOM Server runs a surrogate agent for each agentless device, the maximum supported number of agentless devices per MOM server is 10. You could install more servers to reach up to 60 agentless devices.
