Hybrid Cloud Monitoring Module by using Deltacloud.
This tool is for Zabbix Loadable Module.

Zabbix loadable modules is supported over Zabbix 2.2.0.

• Automatically registration EC2 instances information.
• Automatically registration EC2 CloudWatch metrics information.

• Setup Deltacloud server. (tested in Deltacloud 1.1.3)
• libdeltacloud customized for this tool

Deltacloud is made by Ruby.
So, please install ruby (>= 1.9.2).

And, install rubygems.

You can install deltacloud by using gem command.

If you have installed haml >= 4.0.5, please reinstall haml version 4.0.4

$ sudo gem uninstall haml
$ sudo gem install haml --version=4.0.4

It is not possible to get AWS CloudWatch metrics from Deltacloud 1.1.3. So, please apply patch https://github.com/ike-dai/deltacloud-core/commit/61b690698c949fb7c92607651f1ctc5e02971df966.

$ cd <rubygems dircetory>/deltacloud-core-1.1.3
$ vim lib/deltacloud/drivers/ec2/ec2_driver.rb
    #start_time, end_time, metric_unit_for(p.name), { m.entity => opts[:id]})     <- comment out
    start_time, end_time, metric_unit_for(p.name), {:dimensions => { m.entity => opts[:id]}})

Please start Deltacloud daemon.

$ sudo deltacloudd -i ec2 -p 3000 &

ModuleCloudCacheSize=4M
ZabbixFile="/etc/zabbix/zabbix_server.conf"

Notes: cloud_module.conf must be placed under "/etc/zabbix" directory.

Please set LoadableModulePath,LoadableModule in zabbix_server.conf(or zabbix_agentd.conf)
Loadable Module is used in Zabbix Server or Zabbix Agent.

• When you can use in Zabbix Server(as Simple check item), please edit "zabbix_server.conf".

• When you can use in Zabbix Agent(as Zabbix Agent item), please edit "zabbix_agentd.conf".

  $ vim /etc/zabbix/zabbix_server.conf

  LoadableModulePath=/usr/lib/zabbix/modules LoadableModule=cloud_module.so

Please import templates/cloud_module_templates.xml in Zabbix frontend [Configuration] -> [Templates] -> [Import]

By importing this xml, two templates will be added.

• Template Cloud Module
• Template Cloud Module VM

Add host.

For example:

• Host name: AWS Account A
• Host group: Cloud monitoring
• Interface: Any (This module does not use interface information.)
• Templates: Template Cloud Module
• Macros:
  • {$DELTACLOUD_DRIVER} -> ec2 (Now this module support only ec2)
  • {$DELTACLOUD_PASSWORD} -> AWS API Secret key
  • {$DELTACLOUD_PROVIDER} -> ap-northeast-1 (support any other region name)
  • {$DELTACLOUD_URL} -> http://localhost:3000/api (please set your deltacloud URL)
  • {$DELTACLOUD_USERNAME} -> AWS API Access key

When these settings are finished, monitoring the status of AWS will start automatically.

Please send feedback to me.
