Install MRTG di Debian Etch

Akhirnya bisa juga sinau install mrtg di debian Etch. Mrtg adalah Multi Router Traffik Grapher, yaitu grafik untuk bisa melihat traffik yg lewat di router kita.

Sebelumnya perlu menginstall beberapa packet, yaitu :

1. Snmp dan Snmpd
2. Mrtg

Adapun cara2 installasinya adalah :

Karena dengan debian, installasi mudah dilakukan dengan cara :

#apt-get install snmp, snmpd, mrtg dan biarkan proses itu berjalan sampai selesai..

karena sudah ada cronnya, maka yg kita lakukan hanya :

cp /etc/mrtg.cfg /etc/mrtg.cfg.old
cfgmaker passpublic@localhost > /etc/mrtg.cfg
indexmaker /etc/mrtg.cfg > /var/www/mrtg/index.html

note :

passpublic adalah community yg ada di /etc/snmp/snmpd.conf dan pastikan snmpd sudah berjalan dengan baik.

Untuk mengecek apakah SNMP bekerja dengan baik, jalankan perintah berikut :
snmpwalk -Os -c passpublic -v 1 localhost system.
Perintah di atas akan menghasilkan keluaran seperti berikut :

sysDescr.0 = STRING: Linux frigg 2.6.18-4-686 #1 SMP Mon Mar 26 17:17:36 UTC 2007 i686
sysObjectID.0 = OID: netSnmpAgentOIDs.10
sysUpTimeInstance = Timeticks: (29668961) 3 days, 10:24:49.61
sysContact.0 = STRING: admin
sysName.0 = STRING: jenmannii

root@jenmanni:~# vim /etc/snmp/snmpd.conf

yg harus diedit ada pada perintah:

#sec.name source community
com2sec readonly localhost public12
com2sec readonly 203.190.40.0/24 public23
com2sec readonly 192.168.11.1/32 public23
com2sec readonly 192.168.13.2/32 public23

#sec.model sec.name
group MyROSystem v1 paranoid

group MyROGroup v1 readonly
group MyROGroup v2c readonly
group MyROGroup usm readonly
group MyRWGroup v1 readwrite
group MyRWGroup v2c readwrite
group MyRWGroup usm readwrite

kemudian restart snmpnya dengan perintah :
root@tyr:~# /etc/init.d/snmpd restart

root@tyr:~# cfgmaker public12@localhost > /etc/mrtg.cfg

root@tyr:~# snmpwalk -Os -c public12 -v 1 localhost system

root@tyr:~# cfgmaker public12@localhost > /etc/mrtg.cfg
root@tyr:~# indexmaker /etc/mrtg.cfg > /var/www/mrtg/index.html
kemudian buka file /etc/mrtg.cfg dan pada :

# to get bits instead of bytes and graphs growing to the right
Options[_]: growright, bits <<>

Untuk test apakah mrtg sudah berjalan, silahkan buka di browser dengan mengetikkan : http://alamat_ip/mrtg.

dan pertumbuhan traffik berjalan dari kiri kekanan..
