How is possible truss the kernel

[Eberardo Pipani_1]

Dear all
Duo to install patch PHNE_23456 (or PNHE_22869) to fix a bug in cluster system with multicast transmission, now my system some times are very slow. Is there any command or tool to visit/debug what kernel do durig run time ?

I already use tool "tusc" to truss the system call of running process and in some moment the kernel seem attend some resurces. Is it possible truss the kernel or dump the memory to debug ?
Thank's for your help.
Best regards
Eberardo Pipani

Hi,
I woulnd use such tool on the kernel, I would advise you to use glance, it will show you bottlenecks and more...
If you dont have it, there is a time limited evaluation copy you can install

Good luck
