qclib, which was linked to earlier in the thread, offers all the info. As the
name implies, it is a library, but it comes with a sample program called qc_test
that is intended for debugging purposes. I did some work to provide a standalone
program based to provide the most commonly used data - at least the one *I*
figured might be popular - and which, of course, does not reflect any of the
fields requested above LOL
It seems like there's a use for most of the data provided by qc_test, everybody
seems to find interest in some data. So I'm contemplating externalization of
qc_test output in some shape or form - but is that really consumable?
However, externalizing it is easier said than done, since some of the fields
require a lot of explanation, especially in virtualized environments.
So: Would the output below help, or should we rather have a separate tool with a
more comprehensible format?
Here's some sample output from a Linux guest running under z/VM on top of a z/VM
resource pool (qc_layer_name is the attribute that would reflect the values 1-5
above):
[raspl@jungle qclib]$ ./qc_test
