[gpfsug-discuss] Monitoring capacity and health status for a multitude of GPFS clusters

Interesting and thanks for the latest news.

May I ask: Is there an intent moving forward that TPC and / or other Tivoli
products will be a required part of GPFS?
The concern I have is that GPFS is pretty straightforward at the moment and
has very logical requirements to operate (min servers, quorum, etc),
whereas there are many IBM products that require two or three more servers
just to manage the servers managing the service.. too much. It would be
nice to make sure, going forward, that the core of GPFS can still function
without additional web servers, Java, a suite of middleware, and a handful
of DB2 instance .. :)
