[bhupesh m]

how to check whether my system performing good or not?

it might look a big topic. but simple answer is enough. like what tools or what commands should i use to check CPU, Disk, IO, Network, Process, and if anything else is important to monitor? simply point somewhere and i will try to do something like reading man pages or trying out that commands..

thanks a lot.

Hi:

Perhaps the most comprehensive tool available for HP-UX is 'glance'. If you don't already have it on your ssystem (and you should!) you can obtain a trial copy from one of the Application CDs.

Shalom,

The number one method I use is user complaint.

If they aren't complaining performance is probably fine.

If I'm asked for actual data, I use this tool:

Performance monitoring always starts with a 'normal' measurement, specifically from the applications. This must be in the form of response time for exactly repeatable tasks. Performance issues surface in two ways:

1. Users report that a particular task takes too much time (wall clock time as in a long report).

2. Users report that responce time is too slow. This might be more than 2 seconds for a single query, maybe 5 seconds maximum.

As mentioned, Glance is the only simple way to monitor all the system resources. It is a priced product from HP but for a new sysadmin, there is nothing better. Otherwise, the built-in tools are:

sar
vmstat
top
swapinfo
lanadmin
