ps options.

[joe_91]

Hi All:

I am using the foll. command to observe my production server.
UNIX95 =ps -eo ruser,pid,args,wchan|sort -rn
to find out the the process with highest memory utilization and also what it is waiting for(wchan). Now the last column has an entry like 840c48. what would that mean?we are having problems with occasional runaway process from the appln. what would be the best way to clean this up. Any suggestions are welcome including some scripts to clean up runaway process.

Thanks
Joe.

Hi joe,

That value is the address of an event for which the process is sleeping - i.e. the wchan output.
If it's an "-", it's running.

Hi (again) joe,

A better option would be to use the std HP-UX ps as follows:

ps -ae | sort -rn -k 3,3

This sorts, descending, on the 3rd field of the ps -ae output - which is the minutes value of the time field. The cumulative execution time of the process. This should result in the CPU time hogs at the top.

HTH,
Jeff

Joe,

You are better off getting glance/measureware (buy from HP - but there is a limited trial version - 30 days) to watch your system processes, plus "lsof" doesn't hurt (free):

live free or die

Hi:

I have lsof. How do i use it for this problem? Please advise.

Thanks
Joe.

OK one last time....I forgot you want what it's waiting on...although it only gives you an address. Try this

UNIX95= ps -eo time,ruser,pid,args,wchan | sort -rn -k 1,1

This will put time in the first field & sort descending on it - time hogs up top.

HTH,
Jeff
