This is an external colector Phyton created to improve Zabbix, if you dont wanna wast your time with a lot of bored configurations.
1º step - Downloading BandZabbix
# cd /usr/lib/zabbix/externalscripts
# curl -O https://raw.githubusercontent.com/juliolix/BandZabbix/master/BandZabbix
# chown zabbix.zabbix BandZabbix
# chmod 750 BandZabbix
2º step - Install snmpwalk
# cd /usr/lib/zabbix/externalscripts
# apt-get install snmp
# vim /etc/zabbix/zabbix_server.conf
change
# Timeout=30
to
Timeout=30
3º step - lets test the BandZabbix
# ./BandZabbix 10.0.0.7(ip) huehuebr(community) .1.3.6.1.2.1.31.1.1.1.10.1(OID)
or
# ./BandZabbix 10.0.0.7(ip) huehuebr(community) IF-MIB::ifOutOctets.1(Mibs)
If you note the OID above it is the "ether0" interface's "Mikrotik", however, OIDS aways change. You will need to be patience to find out the correct interface's OID. I can to use MIBs to find out faster. I'm gonna show you how.
# snmpwalk -v 2c -c huehuebr -On 10.0.0.7
.1.3.6.1.2.1.31.1.1.1.10.1 = eth0 interface download
or
IF-MIB::ifOutOctets.1 = eth0 interface download
Final Step - Configuring Zabbix
- Create host
- Create Item
Result: Status = Enabled
You can also configure UPLOAD just setting correct OID Interface, create new item to do it.
Exemple using MIBs.
