Nagios Email notifications
Hi experts,
I have set up Nagios 3 monitoring some machines and their services. I am now trying to set up email notifications. I have installed the following on the linux box: eSMTP- run procmail I can send emails with the following line: echo "test" | /usr/bin/esmtp - C ~/esmtprc me@outsideemailaddress - f me@internalemailaddress This sends me an email from our mail server. However when i try: mailx -s tacos myemail@email.com this just hangs. The commands.cfg files contains: # 'notify-host-by-email' command definition define command{ command_name notify-host-by-email command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotificatio$... | /usr/bin/mailx -s "** $NOTIFICATIONTYPE$ Host... } # 'notify-service-by-email' command definition define command{ command_name notify-service-by-email command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotificatio$... | /usr/bin/mailx -s "** $NOTIFICATIONTYPE$ Host } Can i make modifications to these commands to use esmtp and not mailx or any suggestions to getting mailx working with eSMTP. Also how can you force nagios to send email notifications for testing. Thanks for any advice |
Sure you can modify notify-host/service-by-email command_line entry.
Code:
command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotificatio$... | /usr/bin/esmtp -C /full/path/to/nagios/esmtprc_file - f nagios@yourdomain.com Don't forget to restart your nagios after that. |
Hello jackie001:
If you get this to work, please let me know. I am stuck in getting nagios to send notifications. Thanks. |
Thanks for the response.
For esmtp there is no sytax to use a subject line so i has to leave out -s and the following lines. I checked the syntax at the command line and it works! thanks so much. The file now reads: # 'notify-host-by-email' command definition define command{ command_name notify-host-by-email command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /usr/bin/esmtp -C /etc/esmtprc $CONTACTEMAIL$ -f nagios@dpd.ie -X /tmp/esmtp.log } # 'notify-service-by-email' command definition define command{ command_name notify-service-by-email command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /usr/bin/esmtp -C /etc/esmtprc $CONTACTEMAIL$ -f nagios@dpd.ie -X /tmp/esmtp.log } However i still dont recieve emails! The mistake must lie in the config files. Ive been over and over these files maybe you could have a quick look it might be a simple mistake. everything compiles correctly and the web interface is working perfectly. The windows.cfg contains the following, all of the host , hostgroup and service definitions are basically the same. Should i also add lines to the host definition like notifications_enabled 1 etc.Is it enough fro it to be in the services definition and the contacts.cfg file define host{ use windows-pcs ; Inherit default values from a template host_name invoicepc ; The name we're giving to this host alias invoicingpc ; A longer name associated with the host address x.x.x.x ; IP address of the host } define hostgroup{ hostgroup_name windows-pcs ; The name of the hostgroup alias Windows PCs ; Long name of the group members invoicepc } define service{ use generic-service hostgroup_name windows-pcs service_description Uptime check_command check_nt!UPTIME contact_groups admins check_period 24x7 max_check_attempts 3 normal_check_interval 5 retry_check_interval 1 contact_groups admins notification_options w,u,c,r notification_interval 1440 notification_period 24x7 } The contacts.cfg file reads: define contact{ contact_name nagiosadmin ; Short name of user use generic-contact ; Inherit default values from generic-contact template (defined above) alias Nagios Admin ; Full name of user host_notifications_enabled 1 service_notifications_enabled 1 host_notification_period 24x7 service_notification_period 24x7 service_notification_options w,u,c,r host_notification_options d,u,r service_notification_commands notify-service-by-email host_notification_commands notify-host-by-email email x@email.com ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS ****** } |
