Nagios is unable to send mails to mailbox & generate tickets

[hoegh]

Hi All,

We are not receiving tickets for the Nagios Critical Alerts.Some hosts are able to send alert and we receive tickets in ServiceNow for them but for the rest of the hosts/services we are only receiving alerts in Nagios and there is no mail in Nagios mailbox and hence no ticket in ServiceNow.
Suggest what can be done?

Thanks & Regards
Hoegh.

Hi @hoegh,

I've read through some of your previous posts and it looks like you've had a few issues with ServiceNow ticket creation. First of all, were you ever able to get it setup and working properly?

there is no mail in Nagios mailbox and hence no ticket in ServiceNow.

Did you assign the ServiceNow user to the host or service object ( see: https://support.nagios.com/kb/article.php?id=552 ).

Have you checked the nagios log file to see if the alerts were sent?

Go to end of /usr/local/nagios/var/nagios.log for the host or service, you should see a line like

Code: Select all

[1476416283] SERVICE NOTIFICATION: servicenow;localhost;Service Status - ntpd;UNKNOWN;notify-service-by-snt;ntpd is stopped

Please let me know.

Hi Benjaminsmith,

Service Now host has already been assigned to the host.
And we did not found any such line at the end of /usr/local/nagios/var/nagios.log for the host or service.
Let us know what can be done now?

Thanks & Regards
Hoegh.

Check your configuration file(s) to ensure that they contain valid
directives and data definitions. If you are upgrading from a previous
version of Nagios, you should be aware that some variables/definitions
may have been removed or modified in this version. Make sure to read
the HTML documentation regarding the config files, as well as the
'Whats New' section to find out what has changed.

Hello @hoegh,

There's an issue with your configuration as nothing is defined:

Error: There are no services defined!
Checked 0 services.
Error: There are no hosts defined!
Checked 0 hosts.

Are you able to roll back to a previous configuration snapshot that is working as intended (other than the ServiceNow issue)? Go to Configure > Quick Tools > Configuration Snapshots.

Aslso, it would be very helpful for us if you can upload or PM me your system profile. To send us your system profile. Login to the Nagios XI GUI using a web browser.
Click the "Admin" > "System Profile" Menu
Click the "Download Profile" button
Save the profile.zip file and upload it to a cloud storage of your choice. You can share a link with me in a personal message.
After you upload the profile please post something in this thread to bring it up in the support queue.

Thank you.

Hi,

It was found that Config files were corrupted after upgrading Nagios to 5.5.7.
So we reverted back the Nagios to its earlier Snapshot & waiting for next upgrade from Nagios.
For Now everything working as expected, So please close this thread.

Thanks & Regards
