IBM Tivoli Monitoring, Version 6.3

Enabling or disabling self-describing agent capability

The self-describing agent environment variable is set to Y to enable the self-describing agent capability at all components by default, with the exception of the hub monitoring server. The environment variable KMS_SDA is disabled (KMS_SDA=N) by default only on the hub monitoring server. All components that connect to the hub monitoring server adjust their self-describing agent function to disabled if the hub monitoring server has the self-describing agent function disabled, or if the hub monitoring server is older and does not support self-describing agents.

This allows control of all self-describing agent enablement from a single point - the hub monitoring server. For more information, see Enabling self-describing agent capability at the hub monitoring server. A best practice is to only use the KMS_SDA variable at the hub monitoring server to control self-describing agent enablement, but it can be controlled at each component:

Tivoli Enterprise Monitoring Server uses the KMS_SDA environment variable.
Tivoli Enterprise Portal Server uses the TEPS_SDA environment variable.
Self-describing agents use the TEMA_SDA environment variable.

You can also use tacmd commands to enable or disable the state of the self-describing agent function at the hub monitoring server, without having to recycle any hub monitoring servers. This control is only applied when the hub Tivoli Enterprise Monitoring Server is configured for self-describing agent capability using the environment variable KMS_SDA=Y. For more information, see Dynamically controlling the hub monitoring server self-describing agent capability.
