Download nmon from here:

Http://www.ibm.com/developerworks/wikis/display/Wikiptype/nmonanalyser

1. Prepare:

1) Log in to the system with the root user

2) create a directory: # mkdir / nmon/script

3) confirm the version: # oslevel, in order to determine which script to use, I use 530

# oslevel-s

5300-09-01-0847

4) upload nmon12e_aix530 to / nmon/script using ftp

5) execute authorization command: # chmod + x nmon12e_aix530

2. Use:

1) use it directly:

. / nmon/nmon12e_aix536-f-N-m / nmon/log-s 30-c 2880

Indicates:

-f output files in standard format: _ YYYYMMDD_HHMM.nmon

-N include NFS sections

-m switch to the path to save the log file

-s is sampled every n seconds, here is 30

-c the number of samples taken, here is 2880, that is, monitoring = 2880 * (30-60-60) = 24 hours

The formula for calculating this number according to the hour is: c=h*3600/s, for example, if you want to monitor for 10 hours and take samples every 30 seconds, then clocks 10 hours 3600 pounds 30 seconds 1200.

2) use crontab regularly:

A. Execute the command: # crontab-e

B. add the following command on the last line:

0 8 * * 1, 2, 3, 4, 5 / nmon/script/nmon12e_aix530-f-N-m / nmon/log-s 30-c 1200

Indicates:

Monday to Friday, starting at 08:00, monitoring for 10 hours (until 18:00 sharp), output to / nmon/log

3. Analysis

1) it will generate * .nmon file in / tmp/nmon and download it to your computer.

2) Open nmon analyser v339.xls, set the security of the macro to a minimum, and open the downloaded * .nmon file.

And save as a file, the generation is in view mode, very intuitive!

F1 f2 f3 f4 f5 program

Minute hour day_of_month month weekday command these fields receive the following values:

Minute 0 to 59

Hour 0 to 23

Day_of_month 1 to 31

Month 1 to 12

Weekday 0 to 6 (Sunday to Saturday)

Where F1 represents minutes, f2 represents hours, f3 represents the day of a month, f4 represents a month, and f5 represents the day of a week. Program represents the program to be executed.

When F1 is *, it means that every minute will be executed. If program,f2 is *, the program will be executed every hour, and so on.

When F1 is aMub, it will be executed from minute a to minute b, and when f2 is amelb, it will be executed from hour a to hour b, and so on.

When F1 is * / n, it is executed every n minutes, f2 is * / n, it is executed every n hours, and so on.

When F1 is a, b, c. It means a, b, c, etc. Minutes to be executed, f2 is a, b, c. It means a, b, c. Hours to execute, other analogies
