Performance toolkit under zVM 5.3...Looking to see a snap shot of CPU utilization and Storage Utilization
Hi, Looking to find some where on one of the performance toolkit screen something that will show me the overall CPU utilization and Storage utilization. We are trying to determine if another IFL is needed or more real storage on the box. Thanks Brian
Re: Performance toolkit under zVM 5.3...Looking to see a snap shot of CPU utilization and Storage Utilization
try screen 35 for a real time minute by minute breakdown of some good values for CPU, xstore and paging. For real storage utilization I'd be more concerned with expanded storage utilization, volume of transfer to/from xstore, and paging bandwidth and utilization. Main storage utilization doesn't really tell us all that much in most circumstances.

Thanks everyone, Under option #2 it shows a Storage utilization of 89% and through CMS if I issue the command q alloc page I see that over 3 3390 mod 3's I have a utilization of 73%.

Re: Performance toolkit under zVM 5.3...Looking to see a snap shot of CPU utilization and Storage Utilization
Storage utilization isn't really an interesting number. Page space utilization is and as Jim indicates, you're paging space is under allocated. The ROT is 50%. Does any of the history screens that David pointed you to show that you did any paging? If not, then you don't have a storage issue. Is expanded storage configured in your z/VM LPAR?

Re: Performance toolkit under zVM 5.3...Looking to see a snap shot of CPU utilization and Storage Utilization
Nobody told why page space should not be filled too much: CP uses block paging, that is it writes multiple pages out with one I/O, the number of pages varies. After a while, the paging areas get fragmented, and CP an have a hard time to find a free spot to store the blocks of pages that it has formed, hence it can have to split up the block. As a result: more CPU usage and more I/O. 2008/6/24 Marcy Cortes [EMAIL PROTECTED]: First, get that 73% number to 50% ASAP. Marcy This message may contain confidential and/or privileged information.

Yes, it would be full of stuff so VM has moved some stuff out. Whether you can tune that down is another story.

You don't _have_ to wait for evening. CP permits you to CPFMTXA spare DASD, and add them on the fly. Whole DASD volumes are recommended for page space. Best practices includes allocating page packs as: PERM 0 0 PAGE 1 END (Actually, it's safest to always reserve cylinder zero on all whole VM DASD as PERM space).

Re: Performance toolkit under zVM 5.3...Looking to see a snap shot of CPU utilization and Storage Utilization
Assuming that you have free slots in the CP_Owned list. It is documented that CP understands and will preserve that part of cylinder 0 if a volume is allocated from 0-nnn as a PAGE or SPOL pack and that doing so is OK. Do you know of an actual problem (in the last 15 years) caused by allocating 0 to END as PAGE or SPOL? Anecdotal evidence does not count; neither do examples from before the time that doing so became supported. There is probably no good reason to leave tracks 1-15 unused on a paging or spooling volume. The only thing that needs protecting on these volumes is cylinder 0 track 0, and a clever CP might even be able to use part of it for these functions. This may be a case of best practices being based on fairy tales, myths, or outdated experience. Granted, for all other devices, it is best to allocate cylinder 0 as perm. There you have a guarantee that the volume label will get wiped out if that cylinder is included in a user minidisk.
