Hi! Im trying to make Prometheus exporter for my OpenLink Virtuoso Server 07.20.3217-pthreads for Linux. I found this page http://docs.openlinksw.com/virtuoso/virtuosofaq28/
It says I can get a lot of perfomanse and usage metrics, but i found only several of them. I read this page http://docs.openlinksw.com/virtuoso/perfdiag/ but it is not very useful.
Cause http://docs.openlinksw.com/virtuoso/fn_status/ is absolutely non-informative, I have to write here((
I want to know how i can get:
general concurrency (what means max N concurrent in client status string?)
clean and dirty cache pages (cache pages means buffers?)
virtual memory swapping warning
Statistics on memory usage for disk caching index-by-index
disk random and sequential read times
Thank you so much if you would help me to find a solution.
