Install MRTG to monitor traffic under FreeBSD

In order to ensure the efficient operation of the network, we often need to control the flow of the network. This paper gives the method of using MRTG to monitor the traffic under FreeBSD.

1. Install net-snmpd first:

Cd / usr/ports/net/net-snmp; make install; rehash

2. Then modify the configuration of snmpd:

Ee / etc/rc.conf

Add the following settings:

Snmpd_enable= "YES" snmpd_flags= "- p / var/run/snmpd.pid" ee / etc/hosts.allow

Add the following:

Snmpd: localhost: allow ee / usr/local/share/snmp/snmpd.conf

Add the following:

Rocommunity mrtgmgrsyslocation FreeBSDsyscontact Bluewolfsysname localhost

3. Then start snmpd:

/ usr/local/sbin/snmpd-P / var/run/snmpd.pid

4. Install MRTG:

Cd / usr/ports/net/mrtg; make install; rehash

5. Set up the WEB directory of MRTG:

Mkdir / usr/local/apache/htdocs/mrtg

6. Generate configuration file:

Cfgmaker\-- global 'WorkDir: / usr/local/apache/htdocs/mrtg'\-- global' Options [_]: growright, bits'\-- global 'Language: chinese'\ mrtgmgr@localhost\ > / usr/local/etc/mrtg/mrtg.cfg

7. Generate web page files:

Indexmaker\-title 'MRTG-bluewolf's FTP Avarage Load'\-addhead=''\-output / usr/local/apache/htdocs/mrtg/index.html\-columns=1\-nolegend\ / usr/local/etc/mrtg/mrtg.cfg

8. Run MRTG:

/ usr/local/bin/mrtg / usr/local/etc/mrtg/mrtg.cfg

Run time will prompt an error, ignore, run 3 times in a row, the system no longer prompts an error.

9. Set up to run MRTG automatically every 5 minutes:

Crontab-e

Then enter the following:

0 usr/local/bin/mrtg 5 10 15 15 20 25 30 35 40 45 50 55 * / usr/local/bin/mrtg / usr/local/etc/mrtg/mrtg.cfg-- logging / var/log/snmp/smthome.log

Note:

1. You don't need to install snmpd to catch the switch, but you need to install snmp.

2.RunAsDaemon: yes

Refresh: 300

# No need for crontab-e
