If for any reason you need to revoke an agent, for example when a system with a running agent is compromised, you can delete the agent resource from the system. Any subsequent request will fail verification.
Use the vRealize Operations Manager user interface to revoke the agent certificate by removing the agent resource. For more information, see Removing the Agent Resource.
When the system is secured again, you can reinstate the agent. For more information, see Reinstate an Agent Resource.
