Diag 9C are low cost, Diag 44 not so much. 50 is a low number.

Thanks Christian.
There is no pagging (swapping) here besides just regular kernel's house
keeping (vm.swappiness =5 )
rhel 7 doesn't give me diag_stat in the debug filesystem hmm

So you at least had some time where you paged out memory.
If you have sysstat installed it would be good to get some history data of
cpu and swap.
You can also run "vmstat 1 -w" to get an online you on the system load.
Can you also check (as root)
/sys/kernel/debug/diag_stat
2 times and see if you see excessive diagnose 9c rates.
In the performance monitor toolkit it shows around 12.000 diag x'9c' /s
and 50 x'44'
But at this time of a day everything is calm. i will check again tomorrow.
Lot's of diag x'9c' would indicate too many virtual cpus right?
