Fibre channel performance monitoring - API

[Petr Havel]

Hello,
for monitoring performance of disks attached via fibre channel (SAN) there is SDA command FC PERFORMANCE.
We'd like to access the same performance data from within an application, possibly via QIO calls. Is there any reference for the FC controller API?

Petr,

welcome to the OpenVMS ITRC forum.

I doubt, that there is a published interface to collect the FC performance data.

Note that T4 includes T4$FC_MONITOR_*.EXE, which will collect this kind of data when running the HP T4 tool.

You would have to directly ask HP about this.

Volker.

There's no public api. It's all undocumented, so if you would use it it may break in the future. If you want the gory details and have vms listings you may want to look at [scsi]fc$sda.lis to see how it's done.
