Nagios Support Forum

Posted: **Sun Mar 10, 2019 4:49 pm**

Dear forum members,

I would appreciate please support me with the scaling configuration .. I have tried some configurations without success.

I have three areas: Infrastructure, security and support, in this case, what I intend is that Nagios notify me every 30 minutes to the security area when the host is inactive and every 60 escalating notifications to the other areas.

For the delivery of the notifications I have configured postfix with Exchange, in fact it worked fine before adding the escalation now with this configuration only notifies me every hour when the host is inactive and not every thirty minutes. in the notification I see that it indicates Yes: Incident Escalated but the mail does not arrive at the second and third contact of the escalation.

When I do the configuration check I do not have errors:

[root@localhost nagios]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Try changing your host escalations to this:

Code: Select all

define hostescalation{
    hostgroup_name		FW
    first_notification      2
    last_notification       0
    notification_interval   60
	escalation_period  24x7
	escalation_options d,r
    contact_groups          infraestructura,soporte
}

define hostescalation{
    hostgroup_name		FW
    first_notification      1
    last_notification       0
    notification_interval   30
	escalation_period  24x7
	escalation_options d,r
    contact_groups          seguridad
}

Dear ssax,

After the suggested changes I still have the problem that the escalated notification does not reach the support user (user3ctx). If I see that it already notifies me every thirty minutes (some cases in 15 minutes) when a host is off and also does the scaling, I still have doubts about the correct configuration, the support is appreciated.

Best regards.

Please zip up your entire nagios/etc directory with all your configuration files and PM it to me so that I can look through them to figure out what's going on.

Send your status.dat file as well, you can find it with this command:

Code: Select all

find / -name status.dat

Thank you

What does the notifications report look like for this? I want to see what each contact's notification command is listed as. Does it show user3ctx in there for it?

Please PM me your /usr/local/nagios/var/objects.cache file as well.

Please go to the Nagios Core web interface and then click on the link on the left hand side that says Notifications, send me an example of the output so that I can see if user3ctx is listed. Based on the config user3ctx should have received it.

Additionally, user3ctx looks to be using these notification commands"

Code: Select all

	service_notification_commands	notify-service-by-email-html
	host_notification_commands	notify-host-by-email-html

Are those the proper ones?

Dear ssax,

Attached screenshots ..

Greetings.

You Contact Notifications screenshot shows that user3ctx was notified:

That means that Nagios did what it was supposed to do and tried to fire off the notification.

So if user3ctx did not receive the email, that means that one of these things happened:
- Your notify-host-by-email-html command failed.
-- Please check your script that you are using to send it, there is something wrong with it for this user
- The script worked but whatever you submitted it to is having a problem (queue full, delayed, etc)

Please zip up and attach this entire directory so that we can see what is occurring:

Code: Select all

/usr/local/nagios/libexec/php-html-email

Thank you
