Nmon log file aix

The memory dump is readable and can be used when the command is recording the data. By default, disks are listed per line. For EMC disks, specify a value of By default, the value is the hostname. You cannot specify the -t , -T , or -Y flags with each other.

The timestamp is recorded in the. The value of the number parameter ranges from 4 through For NMON analyzer, use the values 4 or 8. By default, the recording is done every seconds for 96 times. This flag is equivalent to -ft -s -c By default, the recording is done every 30 seconds for times. This flag is equivalent to -ft -s 30 -c You cannot specify the -t , -T , or -Y flags together.

So now i will have two log files as below. Can nmon be customized? Hi, my name is Steve Ngai from Malaysia.

This is my first post. Hope to learn more about Unix from this forum. My first question is can nmon be customized? Can I pass it some nmon option to automatically see Hi the following c-code utilizing the 'read ' man 2 read method cant read in files larger that 2gig. Hi I've found a strange problem on ubuntu64bit, that limits the data you are allowed to allocate on a 64bit platform using the c function 'read ' The following program wont allow to allocate Red Hat.

However, I ran into problem with the binary file. HI, I have downloaded nmon 3. Help with nmon utility. Has anyone done such a thing? I know that you can run the nmon output to The problem is that this process is execute manualy and I need to meake automatic.

How can I do That. Sorry for my english!! Another NMON.
