Opened: Oct 12, 2017

Severity: 4-Minor


The version of the SASP monitor requests updates only from the SASP GWM (Global Workload Manager) for members whose state has changed from what the GWM last reported. The previous version of the SASP monitor requested periodic updates for all members monitored by the GWM.


This change in behavior from the previous SASP monitor implementation has not been confirmed to cause any observable symptoms. If any symptoms are observed which are suspected to be the result of this change, a support request should be opened with F5 support for further investigation.


Running the version of the SASP (Server/Application State Protocol) monitor included in post-12.1.2 BIG-IP software. Note: This behavior does not occur with previous versions of the SASP monitor, included in pre-12.1.2 versions of BIG-IP software.
