Two. Configuring the Nagios Host File

~]# vi/etc/nagios/objects/nrpehost.cfgdefine service{        use                             generic-service                 HOST_NAME                       nrpehost        service_description             CHECK LOAD        check_command                   Check_nrpe!  Check_load        notifications_enabled            1        event_handler                    process_snapshot        }

" enable_event_handlers " /etc/nagios/nagios.cfg enable_event_handlers=1

Three. Configure the Nrpe node

~]# vi/etc/nrpe/Nrpe.cfgcommand[process_snapshot]1 | Tail-n +8 | Sort-rn-k9 | Head-n20 >/tmp/proc_snap.log# allow command with parameter Dont_blame_nrpe=1

Four. Test remote execution

# See if a file can be created

Five. Experiment Test adjustment

' Load ' /etc/nrpe/nrpe.cfgcommand[check_load]0.7,0.6,0.51,3 ,5~]# vi/etc/nagios/objects/templates.cfgnormal_check_interval           1
