IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Autonomous mode and autonomous agents
This section provides information on both switching from a secondary monitoring server back to the primary hub monitoring server in autonomous mode and achieving high availability when using the autonomous agent.
Autonomous mode ensures event information is not lost when communications are lost between an agent and its monitoring server. Agent autonomy comprises the following two running modes:
- Managed mode
- Agents come in either of the following two flavors: a fully connected agent to the Tivoli Enterprise Monitoring Server. While in this mode, the agent behaves as agents traditionally do. But, a partially connected agent runs in a semi-autonomous mode; that is, it is disconnected for some time from the monitoring server.
- Unmanaged mode
- Such agents are fully autonomous and need not be connected to a monitoring server at all.
- Achieving High-Availability with the autonomous agent
- Autonomous mode agent switch from a secondary monitoring server back to the primary hub monitoring server
