gathering I/O statistics from devices in SAN...

wondering what would be a way of measuring reads and writes to devices on an OpenVMS cluster that are defined in a EMC SAN... I am not familiar with EMC toolkit stuff so I am asking as OpenVMS Sysadmin.

Re: gathering I/O statistics from devices in SAN...

Is there an issue why you can't use standard OpenVMS performance utilities?

If you want to measure statistics inside the EMC box ask EMC for the "Deltamark" kit. They use this for measuring performance on the Symmetrix and for capacity planning.

Re: gathering I/O statistics from devices in SAN...

I would be appreciative of any suggestions that you may have regarding specific VMS measuring tools... I am familiar with MONITOR at the very least.. not familiar with Capacity Planning tools..

T4 is a very good tool and best of all it's free (although "unsupported"). If your version of VMS is 7.3-2 or lower you can download it from:

http://h71000.www7.hp.com/openvms/products/t4/index.html

If you are at a higher version of VMS, e.g. 8.3, you can send email to the T4 maintainer (there's a link on that website) and request the beta kit.

If you have any questions on T4 installation, usage, etc. you can ask your questions here as most of the people here are T4 knowledgeable. Good luck.

wow, genius... apparently this (T4) is the product the previous SysAdmin chose to use for his Capacity Planning reporting and is alreday installed on this cluster (v7.3-2)... now I just need to figure out how to get some metrics.. ( hope it is intuitive ).. thanks very much Edgar.. will start looking at this..

You should check out TLVIZ and CSVPNG on the T4 website. TLVIZ installs on your PC and is a great tool for visualizing T4 data.
