Tivoli Enterprise Monitoring agents
This section describes agent environment variables to consider when tuning the Tivoli Monitoring environment.
- CTIRA_RECONNECT_WAIT
- Time interval, in seconds, for the agent to wait between attempts to register with a Tivoli Enterprise Monitoring Server. The default value is 600 seconds. Consider setting this value to a value equivalent to the CTIRA_HEARTBEAT setting, which is specified in minutes. For example, if the CTIRA_HEARTBEAT value has been set at 3 minutes, consider setting CTIRA_RECONNECT_WAIT to 180 seconds.
- CTIRA_MAX_RECONNECT_TRIES
- Number of consecutive times without success the agent attempts to connect to a Tivoli Enterprise Monitoring Server before giving up and exiting. The default value is 720. Using the default value along with the default CTIRA_RECONNECT_WAIT setting, the agent attempts to connect to the Tivoli Enterprise Monitoring Server for 432000 seconds (5 days) before giving up and exiting. If you lower the value for CTIRA_RECONNECT_WAIT, consider increasing this value to maintain an equivalent retry period. For example, if you lower the CTIRA_RECONNECT_WAIT value to 180 seconds, consider increasing this value to 2400.
