collects data as well and the data is stored automatically in /etc/perf/** but as far as I know there is no possibility to define any values like count or intervals - all you get is the default - and you would need to run it as well through either topasout or nmon analyzer or the smitty panel to really have useful data ...
I hope this helps,

Hi,
I'm using topas to monitor CPU and Disk activity including paging space. Previously, I can see the percentage activity of the disk under column "BUSY%", now I can no longer view it (it's all zero), unless I will run IOSTAT 2 simultaneously. What would be the cause of this?
Thanks, (2 Replies)

Hi,
I want to know how to redirect the output of topas -P to a file in a readable format. I tried doing it by using

perf-trace
PERF-TRACE(1) perf Manual PERF-TRACE(1)NAME
perf-trace - strace inspired tool
SYNOPSIS
perf trace
DESCRIPTION
This command will show the events associated with the target, initially syscalls, but other system events like pagefaults, task lifetime
events, scheduling events, etc.
Initially this is a live mode only tool, but eventually will work with perf.data files like the other tools, allowing a detached record
from analysis phases.
OPTIONS -a, --all-cpus
System-wide collection from all CPUs.
-e, --expr
List of events to show, currently only syscall names. Prefixing with ! shows all syscalls but the ones specified. You may need to
escape it.
-o, --output=
Output file name.
-p, --pid=
Record events on existing process ID (comma separated list).
-t, --tid=
Record events on existing thread ID (comma separated list).
-u, --uid=
Record events in threads owned by uid. Name or number.
-v, --verbose=
Verbosity level.
-i, --no-inherit
Child tasks do not inherit counters.
-m, --mmap-pages=
Number of mmap data pages. Must be a power of two.
-C, --cpu
Collect samples only on the list of CPUs provided. Multiple CPUs can be provided as a comma-separated list with no space: 0,1. Ranges
of CPUs are specified with -: 0-2. In per-thread mode with inheritance mode on (default), Events are captured only when the thread
executes on the designated CPUs. Default is to monitor all CPUs.
--duration: Show only events that had a duration greater than N.M ms.
--sched: Accrue thread runtime and provide a summary at the end of the session.
-i --input Process events from a given perf data file.
