nagios cookbook

Build Status

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:

  1. 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.
  2. Searches all available roles/environments and builds a list which will become the Nagios hostgroups.
  3. Places nodes in Nagios hostgroups by role / environment membership.
  4. Installs various packages required for the server.
  5. Sets up configuration directories.
  6. Moves the package-installed Nagios configuration to a 'dist' directory.
  7. Disables the 000-default VirtualHost present on Debian/Ubuntu Apache2 package installations.
  8. Templates configuration files for services, contacts, contact groups, templates, hostgroups and hosts.
  9. Enables the Nagios web UI.
  10. 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

Pager Duty

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

nagios Cookbook CHANGELOG

This file is used to list changes made in each version of the nagios cookbook.

7.0.0

Feature

  • Added providers for all nagios configuration objects.
  • Added wiki pages explaining the providers.
  • Added wiki pages explaining the databags.

Development

  • Updated chefspec (4.2.0)

Extra note

  • Please test this version before using it in production. Some logic and attributes have changes, so this might break your current setup.

6.1.2

Feature

  • Allow defining parents in the unmanaged hosts data bag so you can build the host map.

Bug

  • Setup Apache2 before trying to configure the webserver so paths will be created
  • Installed EPEL on RHEL so package installs work
  • Set the Apache log dir to that provided by Apache since the Nagios log dir is now locked down to just the nagios user / group
  • Template the resource.cfg file on RHEL platforms to prevent check failures
  • Fix cgi-bin page loads on RHEL systems
  • Fix CSS files not loading on Debian based systems

Development

  • Updated Test Kitchen dependency to 1.3.1 from 1.2.1

6.1.0

Bug

  • Fix missing CSS files on RHEL/Fedora package installs
  • Ensure the source file for Nagios is always downloaded to work around corrupt partial downloads
  • Fixed permissions being changed on the resource directory during each run on RHEL systems

Improvement

  • Remove support for SSL V2 / V3 (Apache2/NGINX) and add TLS 1.1 and 1.2 (NGINX)
  • 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

  • Fix normalized hostnames not normalizing the hostgroups
  • Don't register the service templates so that Nagios will start properly
  • Require Apache2 cookbook version 2.0 or greater due to breaking changes with how site.conf files are handled

Improvement

  • Added additional options for perfdata

New Feature

  • Added the ability to specify a URL to download patches that will be applied to the source install prior to compliation

v6.0.2

Bug

  • Remove .DS_Store files in the supermarket file that caused failures on older versions of Berkshelf

v6.0.0

Breaking changes

  • NRPE is no longer installed by the nagios cookbook. This is handled by the NRPE cookbook. Moving this logic allows for more fined grained control of how the two services are installed and configured
  • Previously the Nagios server was monitored out of the box using a NRPE check. This is no longer the case since the cookbooks are split. You'll need to add a services data bag to return this functionality
  • RHEL now defaults to installing via packages. If you would like to continue installing via source make sure to set the installation_method attribute
  • node['nagios']['additional_contacts'] attribute has been removed. This was previously used for Pagerduty integration
  • Server setup is now handled in the nagios::default recipe vs. the nagios::server recipe. You will need to update roles / nodes referencing the old recipe

Bug

  • htpasswd file should be setup after Nagios has been installed to ensure the user has been created
  • Ensure that the Linux hostgroup still gets created even if the Nagios server is the first to come up in the environment

  • Properly set the path for the p1.pl file on RHEL platforms
  • Ensure that the hostgroups array doesn't include duplicates in the even that an environment and role have the same name
  • Only template nagios.cfg once
  • Fix ocsp-command typo in nagios.cfg
  • Fix bug that prevented Apache2 recipe from completing

Improvement

v5.3.0

Breaking changes

  • Directories for RHEL installations have been updated to use correct RHEL directories vs. Debian directories. You may need to override these directories with the existing directories to not break existing installations on RHEL. Proceed with caution.

Bug

  • Cookbook no longer fails the run if a node has no roles
  • Cookbook no longer fails if there are no users defined in the data bag
  • Cookbook no longer fails if a node has no hostname
  • Cookbook no longer fails if the node does not have a defined OS
  • Fix incorrect Pagerduty key usage

  • 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
  • COOK-2389 The logic used to determine what IP to identify the monitored host by has been moved into the default library to simplify the hosts.cfg.erb template
  • A Vagrantfile has been added to allow for testing on Ubuntu 10.04/12.04 and CentOS 5.9/6.4 in multi-node setups
  • Chef spec tests have been added for the server
  • Gemfile updated to use Rubocop 0.15 and TestKitchen 1.0

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-1553] - Nagios: check_nagios command does not work if Nagios is installed from source

  • [COOK-2150] - hostgroups data bag search doesn't respect the multi_environment_monitoring attribute
  • [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
