TODO: nagiosgraph. NEEDS TESTING!!
A.- Looks like we need this in commands.cfg :
define command {
command_name process-service-perfdata-for-nagiosgraph
command_line /usr/local/nagiosgraph/bin/insert.pl
}
B.- And this in templates.cfg :
define service {
name graphed-service
action_url /nagiosgraph/cgi-bin/show.cgi?host=$HOSTNAME$&service=$SERVICEDESC$' onMouseOver='showGraphPopup(this)' onMouseOut='hideGraphPopup()' rel='/nagiosgraph/cgi-bin/showgraph.cgi?host=$HOSTNAME$&service=$SERVICEDESC$&period=week&rrdopts=-w+450+-j
register 0
}
C.- Then we need to add 'graphed-service' to services in localhost.cfg for example:
# Define a service to "ping" the local machine
define service {
use local-service,graphed-service; Name of service template to use
host_name localhost
service_description PING
check_command check_ping!100.0,20%!500.0,60%
}
D.- In these in /etc/nagios/nagios.cfg : - NEEDS TO BE VERIFIED
process_performance_data=1
service_perfdata_file=/tmp/perfdata.log
service_perfdata_file_template=$LASTSERVICECHECK$||$HOSTNAME$||$SERVICEDESC$||$SERVICEOUTPUT$||$SERVICEPERFDATA$
service_perfdata_file_mode=a
service_perfdata_file_processing_interval=30
service_perfdata_file_processing_command=process-service-perfdata-for-nagiosgraph
