This article shows you how to achieve traffic monitoring MRTG in the Linux server, the content is concise and easy to understand, it will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

MRTG

MRTG can analyze network traffic, but it must rely on the SNMP protocol. The collected data will be generated into a HTML file and displayed in the form of a picture.

1. Install some dependent software

[root@localhost bandwidthd-2.0.1] # yum install-y net-snmp

2. Configure snmp and edit the configuration file "/ etc/snmp/snmpd.conf"

[root@localhost bandwidthd] # gedit / etc/snmp/snmpd.conf

View systemview included .1.3.6.1.2.1.1

View systemview included .1.3.6.1.2.1.25.1.1

View systemview included .1.3.6.1.2.1.2

3. Start the snmp service

[root@localhost bandwidthd] # service snmpd start

Starting snmpd: [OK]

[root@localhost bandwidthd] #

4. Download the bandwidthd software (https://oss.oetiker.ch/mrtg/pub/?M=D), or install it online by yum

[root@localhost bandwidthd] # yum install-y mrtg

5. Modify the configuration file "/ etc/httpd/conf.d/mrtg.conf"

[root@localhost bandwidthd] # gedit / etc/httpd/conf.d/mrtg.conf

Order deny,allow

# Deny from all / / this sentence should be commented out

Allow from all / / here is all, which allows all ip to be detected

Allow from:: 1

# Allow from .example.com

6. Generate the mrtg file and make some modifications.

[root@localhost bandwidthd] # cfgmaker public@192.168.0.113 > / etc/mrtg/mrtg.cfg / / generate a file. Note that the ip address needs to be set by the user.

[root@localhost bandwidthd] # gedit / etc/mrtg/mrtg.cfg / / modify the file

# for UNIX

WorkDir: / var/www/mrtg / / is currently on the centos system, so this sentence is uncommented. This path is the path of the web page under apache

# or for NT

# WorkDir: C:\ mrtgdata

# Global Defaults

# to get bits instead of bytes and graphs growing to the right

Options [_]: growright, bits / / remove comments

7. Generate html file and execute three instructions

[root@localhost bandwidthd] # env mrtg/ etc/mrtg/mrtg.cfg / / the first time

2018-08-22 14:50:00, Rateup WARNING: / usr/bin/rateup could not read the primary log file for 192.168.0.1138.2

2018-08-22 14:50:00, Rateup WARNING: / usr/bin/rateup The backup log file for 192.168.0.1138.2 was invalid as well

2018-08-22 14:50:00, Rateup WARNING: / usr/bin/rateup Can't remove 192.168.0.113_2.old updating log file

2018-08-22 14:50:00, Rateup WARNING: / usr/bin/rateup Can't rename 192.168.0.113_2.log to 192.168.0.113_2.old updating log file

[root@localhost bandwidthd] # env mrtg/ etc/mrtg/mrtg.cfg / / the second time

[root@localhost bandwidthd] # env mrtg/ etc/mrtg/mrtg.cfg / / the third time

8. Type "127.0.0.1/mrtg/192.168.0.113_2.html" in the browser so that you can access it
