Recently I fixed Partner Agent issue for one of my production Target Agent, which had a partner agent assigned but was on development server. This ideally should not be the case as partner agent plays a very important role in monitoring. When primary agent is unavailable, it is very important to pick correct Partner agent to make sure monitoring is not affected.
Partner Agent is an agent which in addition to performing its regular functions, also remotely monitors the status of its assigned Management Agent and its host. OMS automatically assigns Partner Agent using built-in algorithm.
Partner Agent can be changed anytime, by using emcli verb “manage_agent_partnership“.
