COMMANDS.CFG - SAMPLE COMMAND DEFINITIONS FOR NAGIOS 3.0.3
Last Modified: 05-31-2007
NOTES: This config file provides you with some example command definitions
that you can reference in host, service, and contact definitions.
You don’t need to keep commands in a separate file from your other
object definitions. This has been done just to make things easier to
understand.
###############################################################################
################################################################################
SAMPLE NOTIFICATION COMMANDS
These are some example notification commands. They may or may not work on
your system without modification. As an example, some systems will require
you to use “/usr/bin/mailx” instead of “/usr/bin/mail” in the commands below.
################################################################################
‘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/mail -s " $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **” $CONTACTEMAIL$
}
‘notify-service-by-email’ command definition
define command{
command_name notify-service-by-email
command_line /usr/bin/printf “%b” “***** Nagios ***\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$" | /usr/bin/mail -s " $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **” $CONTACTEMAIL$
}
################################################################################
SAMPLE HOST CHECK COMMANDS
################################################################################
This command checks to see if a host is “alive” by pinging it
The check must result in a 100% packet loss or 5 second (5000ms) round trip
average time to produce a critical error.
Note: Five ICMP echo packets are sent (determined by the ‘-p 5’ argument)
‘check-host-alive’ command definition
define command{
command_name check-host-alive
command_line $USER1$/check_ping -H $HOSTADDRESS$ -w 3000.0,80% -c 5000.0,100% -p 5
}
################################################################################
SAMPLE SERVICE CHECK COMMANDS
These are some example service check commands. They may or may not work on
your system, as they must be modified for your plugins. See the HTML
documentation on the plugins for examples of how to configure command definitions.
NOTE: The following ‘check_local_…’ functions are designed to monitor
various metrics on the host that Nagios is running on (i.e. this one).
