Nagios is sending mails manually but alerts are not coming

[rnjie]

i noticed that i stopped getting email alerts from nagios even though when i look at reports i see that the notification dispatcher actually sent the email notification. Any help will be appreciated

Hello @rnjie,

Which MTA are you currently setup with - SMPT or the default MTA in Linux (typically Sendmail)?

Please verify the correct email settings. Go to Admin > System Config > Email Settings, and then click the Send a Test Email button. In some situations, there can be a firewall blocking outbound SMTP connections.

Often, if this is a connection issue, you can see this is the mail logs. Submit a custom notification and then tail the log file.

SMTP log (phpmailer)

Code: Select all

tail -f /usr/local/nagiosxi/tmp/phpmailer.log

Sendmail

Code: Select all

tail -f /var/log/maillog

thank you for your reply, i found the solution, our nagios was integrated into opsgenie and all email alerts was sent to opsgenie but we were not getting it all of a sudden, we later found out that the api key in nagios didnt match that for opsgenie, still dont know why the key changed. we corrected the key and could receive alerts again.
please close the case
