Which process is using more CPU AIX?
Check what all application related processes are running and which all are utilizing more CPU by running the TOPAS command. Topas command will give you the CPU usage for each process. There are many different topas commands which system admin can use to check CPU usage. This will show memory usage for each command.
Where is high memory utilization process in AIX?
If you want to get the highest virtual memory processes on your system, you can use #svmon -P. The output of topas shows us the memory as Computational percentage, which is the Virtual memory.
How do I check memory on AIX?
STEPS
- Log in as user informix.
- Run the command lsdev -C | grep mem.
- For each device displayed in step 2., run the command:
What is the top command in AIX?
TOP – displays and updates (real time viewer) information regarding processes currently running on your machine. Process ID, CPU time, Memory used, status, command, etc. Regards.
When to check the memory usage in Aix?
AIX Memory Usage – or – Who is using the memory and how? When you run low on AIX memory, before you add more, it is good to check memory use. Common question: I see XX% of Used Memory but I don’t know who is using it and how? A simple question but there is no simple answer as memory use if complex.
How to check CPU usage for AIX Toolbox Tech?
Or you can use or download nmon utility from IBM site, which is good utility for all of your questions regarding CPU/memory/AIO/Disk/FC or so on… You can use “sar -P ALL 1 100”; it will give you per/processor statistics at 1 second intervals for 100 seconds.
What does it mean when CPU usage is unusually high?
In the listing below shows the wa (waiting on I/O) to be unusually high and this indicates there might be I/O bottlenecks on the system which in turn causes the CPU usage to be inefficient. You can check errpt -a output to see if there are any reported issues with the media or I/O on the system.
How much memory does the AIX LPAR have?
In the above example, the virtual memory usage is 16722493/256=65322MBs, which is about 91% of the total memory assigned to the LPAR. Therefore, this system is not over-committed in the terms of memory.
