Please do not make the font any smaller as it is already, thanks.
Check root's crontab if there is already an entry for sa1 and sa2. If there is, you will find something in /var/adm/sa. If not, read up about those 2 tools (man page or IBM Info Center for example) and put entries into root's crontab accordingly.
I added below entries in the cron
But not found any output in /usr/adm/sa folder. So not sure if it is working.
Can I use below commands? Will that give accurate result ? Please advise
1.CPU utilization
2. Memory
will consider inuse memory.
mnon - Not sure on how to redirect only CPU utilization & memory to file.

Are you sure you know what you want to measure at all?
"CPU utilization" and "memory utilization" is about as significant as the football results plus the lottery numbers of last week - summed up to a single number. You need the details and you need to define what you want to know before you even start to monitor. Otherwise you only get a bunch of meaningless numbers.
There is no such thing as a single number to describe any of the above, like there is no single number to describe the weather. There is temperature, air pressure, humidity, wind velocity, etc., but if you add all that up and arrive at "3156" would you know from this number what the weather is like? Perhaps not.
For CPU utilization, depending on what you want to know, the numbers of interest might be: the % of the time the CPU spends working on system calls, user programs, experiencing I/O-wait or idle times, further the percentage of "entitled capacity consumed" (the number of processor resources available to the LPAR versus the number of used real processor time) and maybe some numbers of minor significance too.
For memory utilization this might be: swap file utilization, size of computational memory, number of revolutions of the clock hand, number of pages scanned, file cache hit/miss ratio, size of file cache, some I/O-related numbers in "vmstat -v" and perhaps some other numbers, depending on what your system does and what is likely to be a bottleneck.
Btw.:

This is probably because you used cron to start background processes. They are probably still running. Remove the trailing "&" and redirect any possible output.
In my oracle db server we have 15 cores (power8). The output of the vmstat is as below.

Hi all,
Been reading a lot of the cpu load and its "analogy of it to car traffic path of expressway"
From wiki
Most UNIX systems count only processes in the running (on CPU) or runnable (waiting for CPU) states. However, Linux also includes processes in uninterruptible sleep states... (13 Replies)
We have a DB server which is constantly utilised above 95% above.
This is becoming nuisance when the monitoring team frequently calls to check on it. Frankly I do not know what to tweak or even interpret the outputs.
I noticed constant 30 to 60% in wio column of the cpu utilisation.

hi
We have migrated SCO 5.0.6 into ESX4, but the VM eats 100% of the virtual CPU.
Here is top print from the SCO VM:

79 processes: 75 sleeping, 2 running, 1 zombie, 1 onproc
CPU states: 0.0% idle, 17.0% user,... (7 Replies)
There might be some problem with my server,
because every morning at 7, it's performance become bad with no DB extra deadlock.
But I just couldn't figure it out.
Please give me some advise, thanks a lot...

Hi All,
While creating zone we will mention min and max cpu cores, like
add dedicated-cpu
set ncpus=NUM_CPUS_MIN-NUM_CPUS_MAX
end
Ques1:
Suppose thing that non global zone uses only minimum cores at particular time What the other cores will do, Will it shared to global zone?

Hello everybody.
I have a problem with my AIX 5.3. Recently my unix shows a high cpu utilization with sar or topas.
I need to find what I have to do to solve this problem, in fact, I don't know what is my problem.
