Question on NMON - disable detailed disk statistics
Hi All,
The NMON file is getting generated with file size of more than 70MB for just 40 minute duration on AIX 6.1 box, due to more number of disks (Disk0, Disk1..., Disk22).
With respect to disk related details, I need to have only the disk summary, and disable the detailed disk statistics (tabs getting created for each of these metrics for 23 individual disks : DISKBUSY, DISKBSIZE, DISKXFER, DISKRXFER, DISKREAD, DISKWRITE, DISKWIO, DISKRIO, DISKAVGWIO, DISKAVGRIO, Etc), to reduce the nmon file size.
Can anyone please share me the nmon command for this !?
Thanks,
Raja
