Ubuntu Zabbix Distribution Utility

[swatson2015]

Hello all,

I have written a utility in Perl that I use to deploy the Zabbix Agent to servers in the environment I work in. This utility may or may not be useful to you, and is customized quite a lot to fit my specific environment, but maybe you can customize it for use with yours.

This utility depends on Perl and two Perl modules which can be acquired with CPAN. The modules are JSON::RPC::Client and Data:umper. I have also replaced key variables with placeholders, so please read through the script and add your own variable values in.

This utility will ssh into a list of servers the user provides and install and configure Zabbix, and then send said data to the Zabbix API so that the hosts appear in the frontend. I hope this is helpful to you all. Please let me know if you have any questions. Script is pasted below.

# This script will read from a file a list of IPs seperated by newlines. It will then reach
# out to those IPs and:
# 1. Install a Zabbix Agent
# 2. Configure that agent to send data to a Zabbix Server or Proxy 
# 3. Hit the Zabbix API to add the host to the front end
