Member field - HEALTH

This field is displayed if the GROUP FLAGS field indicates that server-specific (SERVERWLM) WLM recommendations are being used. This health indicator is available only for applications that provide this information to WLM using the IWM4HLTH or IWMSRSRG services, and it indicates the general health for an application or subsystem. Under normal circumstances, or if the server is not providing this information to WLM, the value of this field is 100, meaning the server is 100% healthy.

Any value less than 100 indicates that the server is experiencing problem conditions that are preventing it from processing new work requests successfully, which causes WLM to reduce the server-specific recommendation for this server instance. The lower the value of this field, the greater the reduction in the recommendation provided by WLM.

Restriction: Although WLM uses the health indicator provided by the application to reduce the server-specific recommendation, this information is available for display on an Advisor only if the Load Balancing Agents and the Advisor are running on a z/OS® V1R8 system. A z/OS V1R7 Load Balancing Agent does not provide this information to the Load Balancing Advisor. In this situation, a z/OS V1R8 Advisor shows a normal health indicator of 100, even if WLM is reducing the server-specific recommendation because of an abnormal health indication from the application.
