process tracing

[Chiara Fregonara]

Is there a way to know what a process is doing over a connection and on the system?
I have a process consuming always 100% cpu but seems to do nothing. Glance doesnt'tell me much. It report no system call.

Thanks

You should first check in glance if the process consumes CPU in user space or in kernel (system). If it's user space, you have to enable debugging for the process that is provided by the application itself (if there is any). You can also try to find more details about the user space functions by tracing the process with prospect (http://www.hp.com/go/prospect).

If most CPU is used in kernel (system) space, you can do call tracing with tools like tusc (http://gatekeep.cs.utah.edu).

You can track a process using lsof (freeware) also why not "nice" the process ?

hi,

use lsof which will show you what the process is doing, which program is taking up the cpu and many more.

try this website for a download:
