Hi, Can we have email notification and service check dependency? For example, if the ping and ssh check for a machine is DOWN, don't send email notification for other service check such as check cpu/memory/process? Since this machine is down, of course the other service check of cpu/memory/process w...

Hi, We figured it out. I will post our solution here, in case it may help other people. Problem: By default, the nagios server sorts the based on the hostgroup_name, which is a fixed value specified in database computers table "nagios_hostgroup". This does not supply enough flexibility for...

Hi, I am using Nagios Core open source 3.5.1 on Red Hat Linux 6.7. Now Nagios will send email notification. Also I can view the hosts and services status on Nagios gui. However, I also would like to have Nagios send the status of hosts and services to another application. Where can I insert my code ...

Hi, I am using Nagios® Core™ Version 3.5.1. Now when I log on to http://mynagiosserver/nagios, the hostgroup is listed in the alphabetical order of the hostgroup_name as definied in the /etc/nagios/objects/hostgroups.cfg file. I am wondering if there is a way to list the hostgroups in the alphabetic...

Hi, Thank you for the reply. I have hostgroups.cfg defined, but that's not my question.... I am thinking of how to automate Nagios setup and monitoring with Puppet (or other configuration management system?). On client side, I already have puppet to push NRPE addon to a machine, ensure nrpe.cfg is p...

Hi, I would like to find out what is the general practise for host definition cfg file creation and management. For example, I have about 300 Linux machines to manage. I need to define host.cfg for each machine, right? Then I will have 300 host.cfg files in /etc/nagios/conf.d. Should I use puppet or...

Yes, you can mark this issue as resolved. Thanks!

Hi, Thank you for the reply. It helps me understand more about Nagios... I figured it out. I added this line to /etc/nagios/apach2.conf: IdentityType samAccountName The samAccountName in my Centrify authentication displays just the username without EXAMPLE.COM. Now when I login to nagios, it shows m...

Hi, I figured it out myself :) In /etc/nagios/cgi.cfg, before I used lower case for DomainName. For example: authorized_for_system_information=nagiosadmin,userA@example.com When I check on the “Tactical Overview” page, I found it says "Logged in as userA@EXAMPLE.COM" After I modified all c...

Hi, I am setting up a Nagios server on Red Hat Linux 6.7 using nagios-3.5.1-1.el6.x86_64 rpm. I would like to use Centrify Active Directory for Nagios authentication and authorization. I found two articles about this: https://rravikumar.wordpress.com/2015/08/11/nagios-with-centrify-authentication/ h...
