9.2.2 Enable NRPE monitoring
Enabling NRPE allows you to execute plug-ins (such as check_tcp and check_ping) on the remote Console
server to monitor serial or network attached remote servers. This will offload CPU load from the upstream
Nagios monitoring machine which is especially valuable if you are monitoring hundreds or thousands of
hosts. To enable NRPE:
1.
Select
System > Nagios
and check
NRPE Enabled
2.
Enter the details the user connection to the upstream Nagios monitoring server and see the
sample Nagios configuration example below for details of configuring specific NRPE checks

server with SSL encryption, without SSL, or tunneled through SSH. The security for the connection is
configured at the Nagios server.
