Hi Nagi Kings,
I have a challenge with Nagios. My Nagios server is up,rrd tools and Apan is
also up. I am getting graph for the Ping service and not for anything else
(like Disk, Load ).
The error display is :
Status : Unknown
States information : No perf-definition for service.
The following are the config setting of the machine .
1. services.cfg is edited with the following setting
# Service definition
define service{
use generic-service ; Name of
service template to use
host_name matter
service_description diska
is_volatile 0
check_period 24x7
max_check_attempts 10
normal_check_interval 1
retry_check_interval 1
contact_groups linux-admins
notification_interval 120
notification_period 24x7
notification_options w,u,c,r
name disk
check_command apan!disk!85!95
}
2. RRD has been created with the following command.
rrdtool create /usr/local/nagios/rrd/matter_disk_usage.rrd -s 60
DS:root:GAUGE:300:0:U DS:home:GAUGE:300:0:U RRA:AVERAGE:0.5:1:50400
RRA:AVERAGE:0.5:60:43800
3. cgi.cfg has been edited with the following setting.
matter;disk_usage;/usr/local/nagios/rrd/matter_disk_usage.rrd;/|/export/home
;root:LINE2 home:LINE2;Disk usage;%;
4. serviceextinfo.cfg has been edited with the following setting.
define serviceextinfo{
host_name matter
service_description disk_usage
notes_url
/nagios/cgi-bin/apan.cgi?host=matter&service=disk_usage
icon_image graph.png
icon_image_alt View graphs
}
Note : If I replace the check_command of service.cfg with 'check_command
check_local_disk!20!10!/dev/hda3 ', it works normally with out any graph.
How to get the graph of disk utilization ?
Any help will be appreciated.
Thanks.
with warm regards,
Paraman Pachaimuthu
