Zabbix Installation Script on Centos/Redhat 6.x

Installation on zabbix is quit simple and straight forward, but when you are install multiple servers and want to automate installation it is better to use a script. I would have preferred an ansible setup, but we have non of that on the server, so had to make do with good old shell script.

Zabbix Database Backup Script for `postgres` and `mysql`.

After the zabbix setup is done, we would like to take backup of the database. Here we are doing a complete backup. But if we are looking for only configuration backup then we can ignore the history* tables from the database, but for now we are taking complete backup. Backups are taken everyday and last 3 days backups are stored and rest for removed.

Installing SNMP Builder using `zabbix-extra` on Zabbix Version 2.4.

SNMP Builder/Extra is an add-in for Zabbix. It provides new web interface components to browse MIB trees and values. SNMP OIDs can then be automatically converted into Zabbix items and inserted into a template. The underlying snmpbuilder script uses calls to NetSNMP in order to communicate with devices on the network.

Setting up SNMP Trapper for Zabbix.

Receiving SNMP traps is the opposite to querying SNMP-enabled devices. In this case the information is sent from a SNMP-enabled device and is collected or “trapped” by Zabbix. Usually traps are sent upon some condition change and the agent connects to the server on port 162 (as opposed to port 161 on the agent side that is used for queries). Using traps may detect some short problems that occur amidst the query interval and may be missed by the query data.
