This article mainly shows you "Nagios how to integrate cacti deployment", the content is easy to understand, clear, hope to help you solve doubts, the following let the editor lead you to study and learn "Nagios how to integrate cacti deployment" this article.

The integration of cacti and nagios uses a plug-in of cacti, nagios for cacti (NPC). Its principle is to import the data of nagios into the mysql database (cacti's library) through ndo2db, and then cacti reads the database information to show the results of nagios.

Note: to install nagios, you can refer to the article to deploy the Nagios monitoring system, and to install cacti, you can refer to the article to build a cacti monitoring system. This article is installed on rhel6.0. Pay attention to the version of the system when you refer to it.

1. Install ndoutils:

First, you need to install ndoutils to import nagios data into the mysql database.

Make sure that the development package for mysql is installed to compile ndoutils

Release the ndoutils package for preconfiguration and compilation before compilation

Note: if the installed RHEL6 is a 64-bit system, copy / usr/lib64/mysql to the / usr/lib directory

Next install, not with makeinstall

2. Modify the nagios main configuration file so that NDoutils can be loaded in Nagios

[root@localhost /] # vi / usr/local/nagios/etc/nagios.cfg

Ensure that the following exist:

Check_external_commands=1

Command_check_interval=-1

Event_broker_options=-1

Process_performance_data=1

Add the following line of configuration items:

This completes the addition.

3. Modify the configuration file ndocmd.cfg. The contents of my configuration file are as follows:

4. Modify the configuration file ndo2db.cfg. My configuration file here is as follows:

Here is the user and password and database used by Cacti in mysql, because our npc plugin is used in cacti.

5. Then start NDoutils and Nagios respectively, and add NDoutils to the rc.lcoal file, as the system starts.

6. Install NPC plug-in and enable npc plug-in

Access the WEB management interface of cacti:

In the web console of the cacti system, click the "User Management" link under "Utilites" in the navigation bar, modify the properties of the admin user, select the "Plugin Management" item, and click "Save" to save.

Refresh the cacti console page, and there will be an extra "Plugin Management" link under "configuration" in the left navigation bar. Click this link to enter the plug-in management page, where the button in the "Actions" column loads the npc plug-in and enables the npc plug-in.

Then select "settings" in the right column and click on the label of npc

Check Remote Commands

Nagios Command File Path:/usr/local/nagios/var/rw/nagiosNaNd

IP/nagios/ of the Nagios URL: http://nagios server

Just save it. The configuration of this article is as follows:

At this point, the installation is complete

7. Restart mysql httpd ndo nagios and other services.

[root@localhost /] # service mysqld restart

[root@localhost /] # service httpd restart

[root@localhost /] # service nagios restart

[root@localhost /] # / usr/local/nagios/bin/ndo2db-3x-c / usr/local/nagios/etc/ndo2db.cfg

If ndo2db is already started, restart ndo2db as follows

Execute tail-20 / var/log/messages # # to see if there are any errors. If there is no error, please continue.

Visit http://yourserver/cacti/

Select the npc tab to see the host information detected by nagios. The only drawback is that I am a little slow to open this page.
