Do not receive alert email

[NagiosNewbis]

Hi;

I changed the "max_check_attempts" to 10 but I do not receive any alert email. I saw the alerts 3 times yesterday then it stopped, I want to continue send alert until the problem solved. So, what should I check here?

So currently this service will alert you when the following happens:

It reaches a hard Critical, Warning, or Unknown state, or it Recovers.

The service will be checked every 10 minutes, when a problem is detected it will check every 5 minutes instead, once it has re checked the service every 5 minutes, 10 times it will generate a notification.

When it sends a notification, it will send another every 60 minutes until the problem is resolved, or the state changes "at this point the notifications are stopped until it runs through the above again due to a state change."

This could be why you only saw it a handful of times you may want to change some of these settings around to lessen the time it takes to notify you.

Take a look at this page:

http://nagios.sourceforge.net/docs/3_0/ ... tions.html

Under the Directive Descriptions: section you will be able to see all the options available to you, and what they control.

I found that the attempts is 10/10, how can I reset it? i tried to do it under the webpage of Nagios but I got the error like like ...

Error: Could not open command file '/usr/local/nagios/var/rw/nagios.cmd' for update!

The permissions on the external command file and/or directory may be incorrect. Read the FAQs on how to setup proper permissions.

I disable the retention_status_information, then restart the service, looks like it recheck all service and reset all attempts.

Yes clearing retention.dat will remove all check information. 2 questions, was this original issue ever acknowledged or do you have any escalations set for that service?

after checking the /var/spool/mail/nagios log file, I found that the email was blocked by RBL due to the reply domain is [email protected], but after I changed the host name and the domain in hosts file, I still not able to see my email yet. Also, I cannot see my new nagios mail files in /var/spool/mail generated.

1. I tried to search it but no luck to find such file, where can I locate the nagios mail file again?
2. where can I modify the $CONTACTEMAIL$ variable to show my real email address.
3. Can I test nagios email thru command line.

[sreinhardt]

1) This should always be /var/spool/mail/nagios unless your local mta has changed this setting. can you run the following command:

Code: Select all

tail /var/spool/mail/nagios

2)This is the email address variable under each contact.
3) Yes look at the notify-[host\service]-by-email in the commands.cfg file. This will show exactly how nagios core sends email.
