Hello to everyone,

I can add host and services without any problem. Besides, I can delete too. The problem appears when I want to change any service characteristic as warning or critical values. I change them, save and apply the new configuration. The process finished without problems. I try using /usr/local/nagiosxi/scripts/reconfigure_nagios.sh and via web.

Have you got any idea where can be the problem?

I am using CentOS release 6.6.

Via web ...

Configuration applied successfully.
Success! Nagios Core was restarted with an updated configuration.

Via reconfigure_nagios.sh

So when you modify the warning or critical thresholds, and apply configuration (or run reconfigure_nagios.sh) , changes don't take effect, correct? What is the Nagios XI version that you are currently using? Run the following commands and show us the output:

Code: Select all

uname -a
cat /etc/*release

Also, run:

Code: Select all

su nagios
cd /usr/local/nagiosxi/scripts
./reconfigure_nagios.sh &> /tmp/reconfig.txt

and post the "reconfig.txt" file, that was created in the "/tmp/" directory by running the above command.

I don't see any errors in the output. Let's try a couple of things.

1. Go to: Configure->Core Config Manager->Services->select "localhost" from the "Filter by Config Name" drop-down menu and click on the "View Text Config" actions button (the diskette icon). Show us the "Current Users" service definition. The "default" config should look like this:

Code: Select all

define service {
	host_name			localhost
	service_description		Current Users
	use				local-service
	check_command			check_local_users!20!50
	register			1
	}

2. Go to Configure->Core Config Manager->Services->select "localhost" from the "Filter by Config Name" drop-down menu and click on the "Current Users". Change the warning and critical thresholds in the $ARG1$ and $ARG2$ fields to let's say 1 and 5. Click on "Save". Apply Configuration.

3. Go back to the CCM, click on the "View Text Config" actions button (the diskette icon), and show us the "Current Users" service definition once again. Did the thresholds change. Did they change in the actual config (flat file)?

Code: Select all

cat /usr/local/nagios/etc/services/localhost.cfg

BTW, did you try modifying the threshold via the CCM or by going to:

Code: Select all

Home->Service Detail-><your service>->Configure->Re-configure this service

and modifying the thresholds in the "Monitor the service with this command..." field?

Hello Imiltchev, thanks for your response.

I use all the tools that you told me. Thanks they were very usefull.

I saw that when I apply the changes they were saving on .cfg files. The problem seems to be something about the service status. It not change!
I force that a service from critical status to ok status. For example:

PROCS OK: 45 processes with STATE = RSZDT

I change the service to:

Code: Select all

define service {
	host_name			localhost
	service_description		Total Processes
	use					local-service
	check_command		check_local_procs!10!30!RSZDT!!!!!
	register				1
	}

On advance settings I have:
Performance Data: procs=45;250;400;0;

This service must be critical and I think that performance date range must be 10;30

NOTES:
I am using the lastest version of NCPA on clients.
The NagiosXI version is Nagios XI 2014R2.7

Are you changing the config files themselves (will not work), or are you altering the thresholds through the CCM (proper way)?

Posted: **Wed Jun 17, 2015 10:35 am**

Hello,

I was using the CCM. At last, I checked the database too and the service changes was write properly. The values of warning and critical changed properly but not take effects in web.

Let's stop/start/restart the services - run:

Code: Select all

service nagios stop
killall nagios
service ndo2db stop
service ndo2db start
service nagios start
service mysqld restart
service crond restart

If this didn't fix your issue, go to:

Admin->System Profile->Download Profile

save and PM me the "profile.zip".

Could you run the following to see if this fixes the issue?

Code: Select all

service mysqld stop
cd /var/lib/mysql/nagios
myisamchk -r -f *
service mysqld start
rm -f /usr/local/nagiosxi/var/dbmaint.lock
php /usr/local/nagiosxi/cron/dbmaint.php

Could you upload this file so we can review it?

Code: Select all

/etc/my.cnf

In addition to what tgrip said, I noticed that your php and system time is out of sync.

Code: Select all

===Date/Time====

PHP Timezone: UTC 
PHP Time: Thu, 18 Jun 2015 08:14:35 +0000
System Time: Thu, 18 Jun 2015 04:14:35 -0400

You will need to fix that as this can also be causing issues. Please, follow the steps outlined in the document below:
