Nagios-for-Devstack Configuration Guide
|
|
=======================================
|
|
|
|
Overview
|
|
--------
|
|
|
|
This page describes how to manually install and configure Nagios on devstack.
|
|
After following the steps described here, Nagios will be installed via the OMD
|
|
package (http://omdistro.org/) and will have a basic set of tests for
|
|
monitoring the Devstack VM. It will then be possible to configure a Nagios
|
|
datasource for Vitrage.
|
|
|
|
The following guide is for Ubuntu. With slight modifications it should work for
|
|
other linux flavours. Links for this purpose are added below.
|
|
|
|
Installation
|
|
------------
|
|
|
|
1. Update your repo to include the OMD key:
|
|
::
|
|
|
|
wget -q "https://labs.consol.de/repo/stable/RPM-GPG-KEY" -O - | sudo apt-key add -
|
|
|
|
2. Update your repo with the OMD site. For example, for ubuntu trusty release:
|
|
::
|
|
|
|
sudo bash -c "echo 'deb https://labs.consol.de/repo/stable/ubuntu trusty main' >> /etc/apt/sources.list"
|
|
sudo apt-get update
|
|
|
|
For additional distros, see https://labs.consol.de/repo/stable/
|
|
|
|
3. Install OMD
|
|
::
|
|
|
|
sudo apt-get install omd
|
|
|
|
4. Create a site for nagios with a name of your choosing, for example
|
|
"my_site".
|
|
::
|
|
|
|
sudo omd create my_site
|
|
sudo omd config my_site set APACHE_TCP_PORT 54321
|
|
sudo omd config my_site set APACHE_TCP_ADDR 0.0.0.0
|
|
sudo omd start my_site
|
|
|
|
You can now access your Nagios site here: *http://<devstack_ip>:54321/my_site/omd*.
|
|
::
|
|
|
|
username: omdadmin
|
|
password: omd
|
|
|
|
*Notes:*
|
|
- The default port is OMD uses is 5000, which is also used by OpenStack
|
|
Keystone, and so it must be changed. Port 54321 used here is only an
|
|
example.
|
|
- *APACHE_TCP_ADDR* indicates the address to listen on. Use 0.0.0.0 to
|
|
listen for all traffic addressed to the specified port. Use a different
|
|
address to listen on a specific (public) address.
|
|
|
|
5. Install the Check_MK agent on devstack VM:
|
|
::
|
|
|
|
sudo apt-get install check-mk-agent
|
|
|
|
6. Activate the Check_MK agent, by editing */etc/xinetd.d/check_mk* and
|
|
**setting "disable" to "no"**, and then run
|
|
::
|
|
|
|
sudo service xinetd restart
|
|
|
|
7. In your browser, go to *http://<devstack_ip>:<selected port>/my_site/omd*
|
|
and follow the instructions at this link_ (**"Configuring the first host and
|
|
checks"** section) to configure the nagios host.

|
|
|
|
8. *Vitrage Support.* With Nagios installed, you can now configure a datasource
|
|
for it for Vitrage, by following the instructions here_.
