nagios cookbook

Installs and configures Nagios server. Chef nodes are automatically discovered using search, and Nagios host groups are created based on Chef roles and optionally environments as well.

Requirements

Chef

Chef version 0.10.10+ and Ohai 0.6.12+ are required.

Because of the heavy use of search, this recipe will not work with Chef Solo, as it cannot do any searches without a server.

This cookbook relies heavily on multiple data bags. See Data Bag below.

The system running this cookbooks should have a role named 'monitoring' so that NRPE clients can authorize monitoring from that system. This role name is configurable via an attribute. See Attributes below.

The functionality that was previously in the nagios::client recipe has been moved to its own NRPE cookbook at https://github.com/tas50/chef-nrpe

Platform

Debian 6.X, 7.X
Ubuntu 10.04, 12.04, 13.04
Red Hat Enterprise Linux (CentOS/Amazon/Scientific/Oracle) 5.X, 6.X

Notes: This cookbook has been tested on the listed platforms. It may work on other platforms with or without modification.

Cookbooks

apache2 2.0 or greater
build-essential
nginx
nginx_simplecgi
php
yum-epel (note: this requires yum cookbook v3.0, which breaks compatibility with many other cookbooks)

Recipes

default

Includes the correct client installation recipe based on platform, either nagios::server_package or nagios::server_source.

The server recipe sets up Apache as the web front end by default. This recipe also does a number of searches to dynamically build the hostgroups to monitor, hosts that belong to them and admins to notify of events/alerts.

Searches are confined to the node's chef_environment unless multi-environment monitoring is enabled.

The recipe does the following:

Searches for users in 'users' databag belonging to a 'sysadmin' group, and authorizes them to access the Nagios web UI and also to receive notification e-mails.
Searches all available roles/environments and builds a list which will become the Nagios hostgroups.
Places nodes in Nagios hostgroups by role / environment membership.
Installs various packages required for the server.
Sets up configuration directories.
Moves the package-installed Nagios configuration to a 'dist' directory.
Disables the 000-default VirtualHost present on Debian/Ubuntu Apache2 package installations.
Templates configuration files for services, contacts, contact groups, templates, hostgroups and hosts.
Enables the Nagios web UI.
Starts the Nagios server service

server_package

Installs the Nagios server from packages. Default for Debian / Ubuntu systems.

server_source

Installs the Nagios server from source. Default for Red Hat / Fedora based systems as native packages for Nagios are not available in the default repositories.

pagerduty

Installs pagerduty plugin for nagios. If you only have a single pagerduty key, you can simply set a node['nagios']['pagerduty_key'] attribute on your server. For multiple pagerduty key configuration see Pager Duty under Data Bags.

This recipe was written based on the Nagios Integration Guide from PagerDuty which explains how to get an API key for your Nagios server.

Data Bags

See Wiki for more databag information

You can define pagerduty contacts and keys by creating nagios_pagerduty data bags that contain the contact and
the relevant key. Setting admin_contactgroup to "true" will add this pagerduty contact to the admin contact group
created by this cookbook.

{
  "id": "pagerduty_critical",
  "admin_contactgroup": "true",
  "key": "a33e5ef0ac96772fbd771ddcccd3ccd0"
}

You can add these contacts to any contactgroups you create.

Monitoring Role

Create a role to use for the monitoring server. The role name should match the value of the attribute "node['nagios']['server_role']". By default, this is 'monitoring'. For example:

# roles/monitoring.rb
name 'monitoring'
description 'Monitoring server'
run_list(
  'recipe[nagios::default]'
)

default_attributes(
  'nagios' => {
    'server_auth_method' => 'htauth'
  }
)

$ knife role from file monitoring.rb

Usage

server setup

Create a role named 'monitoring', and add the nagios server recipe to the run_list. See Monitoring Role above for an example.

Apply the nrpe cookbook to nodes in order to install the NRPE client

By default the Nagios server will only monitor systems in its same environment. To change this set the multi_environment_monitoring attribute. See Attributes

Create data bag items in the users data bag for each administer you would like to be able to login to the Nagios server UI. Pay special attention to the method you would like to use to authorization users (openid or htauth). See Users and Atttributes

At this point you now have a minimally functional Nagios server, however the server will lack any service checks outside of the single Nagios Server health check.

defining checks

NRPE commands are defined in recipes using the nrpe_check LWRP provider in the nrpe cookbooks. For base system monitoring such as load, ssh, memory, etc you may want to create a cookbook in your environment that defines each monitoring command via the LWRP.

With NRPE commands created using the LWRP you will need to define Nagios services to use those commands. These services are defined using the nagios_services data bag and applied to roles and/or environments. See Services

enabling notifications

You need to set default['nagios']['notifications_enabled'] = 1 attribute on your Nagios server to enable email notifications.

For email notifications to work an appropriate mail program package and local MTA need to be installed so that /usr/bin/mail or /bin/mail is available on the system.

Example:

Include postfix cookbook to be installed on your Nagios server node.

Add override_attributes to your monitoring role:

# roles/monitoring.rb
name 'monitoring'
description 'Monitoring Server'
run_list(
  'recipe[nagios:default]',
  'recipe[postfix]'
)

override_attributes(
  'nagios' => { 'notifications_enabled' => '1' },
  'postfix' => { 'myhostname':'your_hostname', 'mydomain':'example.com' }
)

default_attributes(
  'nagios' => { 'server_auth_method' => 'htauth' }
)

$ knife role from file monitoring.rb

Cleaned up and removed duplicate code from the web server configuration

New Features

Added the ability to tag nodes with an attribute that excludes them from the monitoring search. See readme for details

Breaking Changes

The /nagios or /nagios3 URLs are no longer valid. Nagios should be installed on the root of the webserver and this never entirely worked

Development

Updated Rubocop rules
Fixed specs to run with Chefspec 4.X

v6.0.4

Bug

v5.3.2

Bug

Remove a development file that was accidentally added to the community site release

v5.3.0

Breaking changes

COOK-4098 Fixed an incorrect example for using templates in the readme
Fixed a typo in the servicedependencies.cfg.erb template that resulted in hostgroup_name always being blank

Improvement

The Yum cookbook dependency has been pinned to < 3.0 to prevent breakage when the 3.0 cookbook is released

v4.0.0

This is a major release that refactors a significant amount of the service configuration to use data bags rather than hardcoding specific checks in the templates. The README describes how to create services via data bags.

The main incompatibility and breaking change is that the default services that are monitored by Nagios is reduced to only the "check-nagios" service. This means that existing installations will need to start converting checks over to the new data bag entries.

[COOK-2186] - add service escalation to nagios
[COOK-2188] - A notification interval of zero is valid but prohibited by the cookbook
[COOK-2200] - Templates and Services from data bags don't specify intervals in the same way as the rest of the cookbook
[COOK-2216] - Nagios cookbook readme needs improvement
[COOK-2240] - Nagios server setup needs to gracefully fail when users data bag is not present

[COOK-2081] - add support for notes_url to nagios_services data bags
