Installation and Use of nmon

 

1. Download

Nmon:
Http://nmon.sourceforge.net/pmwiki.php? N = site. Download

Nmonanalyser

Help:
Http://nmon.sourceforge.net/pmwiki.php? N = site. Documentation

 

Download the binary file and run it directly. Do not install it. It is very convenient.

[Root @ dhdb ~] # Cp nmon/usr/local/bin/nmon

 

You can run nmon directly.

[Root @ dhdb ~] # Nmon-S 300-C 288-F-M/tmp

-S 300: indicates that data is collected every 300 seconds,
-C 288: indicates that data is collected for 288 times, 300*288 = 86400 seconds, which is exactly the data of one day. In this way, once this program is run, a data file of one day will be generated,
-M/tmp: indicates the path of the generated data file.
-F: indicates that the generated data file name has a time

 

Of course, we can also make it automatically monitor, one folder every day, one file every hour, one sample every minute or five minutes

 

For example, on 175,/Oracle/SH

[Root @ dhdb sh] # pwd
/Oracle/SH
[Root @ dhdb sh] # ls
Nmon. Sh

File Content:
[Root @ dhdb sh] # More nmon. Sh
# Author: skate

# Function: Monitor System Information
# Time: 2011/08/05

Npath =/tmp/
# Monitoring per 120 senonds
Nmon-S 120-C 720-F-M $ npath

# Monitoring per 300 senonds
# Nmons-s 300-C 288-F-M $ npath

# Delete file before 365 day
# Find/tmp-name *. nmon-mtime + 365-exec RM {}\;
~
[Root @ dhdb sh] #

 

Scheduled task, started every morning, and generates a file

[Root @ dhdb sh] # crontab-l
0 0 *** sh/Oracle/SH/nmon. Sh>/dev/null 2> & 1

[Root @ dhdb sh] #

 

In the/tmp directory, a nmon file is generated every day. These files are uploaded to Windows machines and the analysis tool "nmon analyser v33g" is opened in Excel ",
Then you can analyze the nmon file.
