Monitoring zVM CPU usage with automated alerts
James Chaplin Systems Programmer, MVS, zVM & zLinux Base Technologies, Inc (703) 921-6220 We had a situation in our shop were CPU in the zVM topped at 100% while the CPU usage in the zLinux Guests remained at their low levels. We use Tivoli ITM to monitor (automated) the CPU on our zLinux guests, but do not have an effective way to capture when zVM starts taking too much CPU in an single LPAR. Does anyone know of how/if ITM (Tivoli) can monitor zVM, or any shareware tool, Is there a Perfkit method to send a message out when the system starts to hold high CPU usage in zVM? We have looked at Velocity, but at the stage have no budget to invest in a tool as zLinux is still viewed as a test (experimental) platform in our shop James Chaplin Systems Programmer, MVS, zVM & zLinux Base Technologies, Inc Customs and Border Protection -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
Re: Monitoring zVM CPU usage with automated alerts
Don't have any manuals handy -- but PERFKIT has alert levels and a way to utilize an exit to do notification (need some way to send email/alert from zVM).. I believe Omegamon XE can monitor zVM... but not sure offhand how records are fed thru TEPS/TEMS.

Re: Monitoring zVM CPU usage with automated alerts
Hi, James. Yes, you can do this using the PerfKit monitoring tool. Take a look at the FCON LIMIT and FCON PROCESS commands in the Pefrkit reference manual. One z/Linux goes production at your shop, go take a good look again at the Velocity products as well. IMHO, they're worth their costs. Good luck.

I'd call it 'futzy'. It works using a DCSS to send data to an Omegamon agent running in a linux virt, which then forwards the data on to the tivoli tems. We've found it both intricate to set up, problematic to keep running and not providing nearly the nice detail and z/VM <-> zLinux interoperational detail you'd get from Velocity.

Renaming dasd references

I've run chccwdev to take the device offline and then detached it before linking again and bringing it online. How can I get the device reference to change ?

Re: Renaming dasd references
You can change your DASD statements (in modprobe.conf on RH -- zipl.conf in SUSE) to include 103 .. I assume you must have something like: DASD=100-102,xxx-xxx (where - is range of 4) You can change this to 100-103,xxx-xxx You will have to reboot (and do a mkinitrd/zipl on RH --- zipl on SUSE) and then things should show up as you want them to.. I also thought I'd heard of a way to specify the dasd device rather than relying on the order of the DASD statement -- maybe someone else has more details?
