Monitoring a mail server

[Jim Pye]

No probs

In the misccommands.cfg I added the following

# 'host-notify-by-sendEmail' send host email via PERL script
define command{
        command_name    host-notify-by-sendEmail
        command_line    /usr/local/bin/sendEmail -f nagios at pyenet.co.nz
-t $CONTACTEMAIL$ -u "Host $HOSTSTATE$ alert for $H
OSTNAME$!" -s mail.pyenet.co.nz -m "***** Nagios  *****\n\nNotification
Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState:
$HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time:
$LONGDATETIME$\n"
        }


This is based on the original send email on host notification default
command. I also created one for the service notification as well.

Email has munged this a bit so synopsis is:

define command{
       command_name   host-notify-by-sendEmail

These 2 are the command defining lines

The command_line below I have broken to make more readable but to work
this all has to be on one line ???

command_line  /usr/local/bin/sendEmail

This bit above will be dependant on where you copy/install the script.

-f is the email from field. This will need to changed to an email
account that the server will allow email to be sent from.

-t is the to email to field. This here uses the $CONTACTEMAILS$ macro.

-u is the subject line. "Host $HOSTSTATE$ alert for $HOSTNAME$!" is
directly from the original send email command.

-s is the server that the email is going to be sent to. Note that this
server must be configured to accept emails from both the -f email
account and the host that this script is running on to avoid relay
denied messages.

-m is the message content. Again taken from the original send email
command. Note that the \n's make the display a bit prettier. "*****
Nagios  *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME
$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n
nDate/Time: $LONGDATETIME$\n"

For other options like attachments etc. just run the sendEmail script
without any options. As the script requires a couple of mandatory
options it prints the help file.

I use this script for all sorts of purposes like emailing log files,
etc. Very handy.

And in the contacts.cfg change the
        service_notification_commands   notify-by-email
        host_notification_commands      host-notify-by-email

to

        service_notification_commands   notify-by-sendEmail
        host_notification_commands      host-notify-by-sendEmail

for each user you wish to use the sendEmail script instead of the built
in email client.
