Re: realtime monitoring of various storage subpools

[kekronbekron]

It may be worth writing a zOS Hot Topics (https://zos-hot-topics.com) article 
about all the new things added to SDSF.
So that the information is easy to share, and for more people to enjoy the new 
stuff.

Me too. Rob and his team are adding outstanding features with every new 
release. The x-mem browsing into foreign address spaces was particularly 
popular in our team.

Have you looked into PFA (Predictive Failure Analysis), particularly its 
PFA_PRIVATE_STORAGE_EXHAUSTION check?

[Rob Scott]

Note that with SDSF for z/OS 2.5, you can issue the "L" action against a 
specific subpool+key combination and this will take you into a detailed view of 
every block of storage. You can then use point-and-shoot on the address to 
invoke the SDSF memory browse function to examine the contents. This works for 
both common storage and private storage for the target ASID.

Dave, if you want to sit there and hit enter to watch things you could try SDSF 
(zOS 2.4) panel AS and subcommand JM.  See if that is what you are looking for.


The Address Space Memory (AS) panel allows authorized users to display the 
storage utilization of address spaces in the sysplex.

Access it with the AS command.



JMDisplay the job's use of memory. (Access the
  Job Memory panel.)

All,

is there another method to monitor subpool usage for a specific address space 
besides Omegamon?   I realize I could take periodic console dumps and look, but 
looking for other methods out of the box.  We have a rogue address space with a 
memory leak, and wanting to track  storage growth (or lack of when leak fixed).

Thanks in advance.

Dave
