IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Enable or disable the self-describing capability at the agent
You can enable or disable the self-described agent capability through a monitoring agent environment configuration variable. Disable the self-describing feature any time you do not want automatic update and propagation of self-described agent application metadata for one or more individual agents. Then, the application support for the agent must be manually installed and activated at the monitoring server and portal server. By default the self-describing capability for agents is turned on.
Best practice is to control the self-describing agent capability from the hub monitoring server. See Enable or disable the self-describing capability at the monitoring server.
Procedure
- On the computer where the monitoring agent is installed, in the Manage Tivoli Enterprise Monitoring Services application, right-click the agent and select Advanced→ Edit ENV file.
- Edit the existing environment variable: TEMA_SDA=Y | N
- On the computer where the monitoring agent is installed, change to the <install_dir>/config/ directory.
- Open the coordinating file:
For single-instance agents: <pc>.ini
For multi-instance agents: <pc>_<instance>.ini file
Where pc is the two-character product code.
- Edit the existing environment variable: TEMA_SDA=Y | N
- Open /qautotmp/kmsparm.kbbenv.
- Edit the existing environment variable: TEMA_SDA=Y | N
- See TEMA_SDA in the IBM Tivoli OMEGAMON XE and Tivoli Management Services on z/OS: Common Planning and Configuration Guide.
What to do next
Restart the monitoring server.You can review the agent support versions in the following ways:
- Review the agent and monitoring server operations logs to determine if the agent is operating in the standard or the self-described agent mode. The Managed System Status workspace has a link to the operations log for each monitoring agent.
- The tacmd listappinstallrecs command returns the application support installation records and the tacmd listSdaStatus command displays the current self-describing agent operational status for all monitoring servers in the environment. Remember that these commands are not available when the monitoring server is not running. See Self-describing agent installation.
