system statistics

Hi all,

I want to use some monitoring commands in DCL scripts in order to determine CPU usage, disk I/O rate, network interface states (utilization, failure, etc...), memory usage, etc. I put these commands in a .com file and run it in regular interval. According some threshold values, the the program gives an appropriate alert.

Can I use the monitor command like "monitor cluster /summary=out.txt"? But, with this command, it records the statistics to the output file continously. I can use /ending qualifier but I can not determine how much time it takes to take full enough statistics. I mean, the output file should contain exactly one statistics per item, not two or more. One CPU usage per cluster node, one I/O rate per disk, one memory usage per cluster node, one network statistics per card, etc... I do not want second statistic for the same item, two CPU statistics per cluster node for instance.
Is it possible, with monitor or other commands..

thanks...

Mustafa,

Check out the T4 add-on, available from the OpenVMS www site. There is also an article on T4 (see http://h71000.www7.hp.com/openvms/journal/v3/index.html#t4)

I use monitor in dcl to get some info.

Re: system statistics


I'll second Bob's endorsement of T4. You can get the kit at http://h71000.www7.hp.com/openvms/products/t4/index.html TLViz is a PC utility to create graphs from T4 data files.

You may also want to look at the ECP Data Collector and Performance Analyzer. See http://h71000.www7.hp.com/openvms/products/ecp/performance-and-capacity-download.html

If you don't have time to do it right, when will you have time to do it over? Reach me at first_name + "." + last_name at sysmanager net

Re: system statistics

Howdy,

I do something similar to Wim. Attached is a modified piece of DCL from a system checker I use. This part checks there isn't a cpu hog (defined by me as a process using 85%+ cpu 15 minutes apart, which catches most of my runaway processes). Shows the principal of using a monitor file, anyway, so can be adapted to meet your needs. BTW, works on VMS Alpha V7.3-1, other versions/platforms may have different number of records in the output file, different location of data within the record etc.

Have fun,
