How to monitor process that consumes 100% during more than 01 hour ?

Hi,

On Linux RedHat 5 ( 2.6.18-194.el5 ) I need to monitor process that consumes 100% CPU during more than 01 Hour.

Are there command lines ? scripts ?

Regards,

A ps command that finds processes with >= 1 hour CPU time

Code:

ps -eo pid,time,args | awk '$2~/:.+:/'

---------- Post updated at 04:45 PM ---------- Previous update was at 04:27 PM ----------

Comparing CPU time with elapsed time seems to meet your requirement

Code:

ps -eo pid,time,etime,args | awk '$2~/:.+:/ && $3~/:.+:/ && substr($2,1,index($2,":")) == substr($3,1,index($3,":"))'

I'm guessing MadeInGermany's output didn't include empty time fields - you'd need to update the awk to check for a non-zero leading (sub)field in the time rather than just checking if it exists.

EDIT: And also handle days somehow...
