Here's an update: I found a seemingly unrelated problem. I had duplicated the notify-host-by-email command into the notify-service-by-email command. While this accounted for the inappropriate message content, fixing it seems to have also fixed the repeating notifications (haven't received any in a while). No idea why fixing the invalid message text would also fix the repeating notifications, but it seems OK now. I'm posting the answer here in case anybody else runs into this problem. The lines below are working nicely on a system that uses postfix as the mailer. This also takes care of postix's sendmail not respecting the -s (subject) command line option. The macros below add the subject to the message. ////////////////////////// from commands.cfg /////////////////////// # 'notify-host-by-email' command definition define command{ command_name notify-host-by-email command_line /usr/bin/printf "%b" "Subject: ** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **\n\n***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n\nService: $SERVICECHECKCOMMAND$Host Output: [$HOSTOUTPUT$]\n\nHost Output (Long): $LONGHOSTOUTPUT$\n\nPerformance Data: $HOSTPERFDATA$\n\n" | /usr/sbin/sendmail -f nag...@example.com $CONTACTEMAIL$ } # 'notify-service-by-email' command definition define command{ command_name notify-service-by-email command_line /usr/bin/printf "%b" "Subject: ** $NOTIFICATIONTYPE$ alert - $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **\n\n***** Nagios @VERSION@ *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nService Output: $SERVICEOUTPUT$\n\nLong Service Output: $LONGSERVICEOUTPUT$\n\nAdditional Info:\n\n$OUTPUT$" | /usr/sbin/sendmail -f nag...@example.com $CONTACTEMAIL$ } ------------------------------------------------------------------------------ Achieve unprecedented app performance and reliability What every C/C++ and Fortran developer should know.
