Nagiosgraph - No “performance data” when increasing “normal_

Postby pankajsain » Tue May 07, 2013 5:25 am

When i increase "normal_check_interval" value from default(10min.) to 15min. or greater for any service, nagios stops receiving performance data in .rrd files.

I also checked it with increasing "perfdata_timeout" value but it didn't work.

Details are:
Code: Select all
Nagios version: Nagios Core 3.5.0 or 3.2.3
plugin version: nagios-plugins-1.4.16
Nagiosgraph version:    nagiosgraph-1.4.4
OS: Redhat 5.8 64bit


Service configuration:
Code: Select all
define service{
          use                 generic-service
          host_name           Server-10
          service_description Disk-Boot Partition Free Space
          check_command       check_nrpe!check_disk_boot_partition
          normal_check_interval 30
      }


PS: Services with default "normal_check_interval" value, giving perfdata continually.

Any help would be appreciated.

Thanks,
pankajsain

Can you show us a screenshot example of a graph on one of your services at a normal check interval, and then a comparative graph of that service with an increased interval no longer graphing RRD data? Thanks!

Thanks for your reply,

Please find the screen-shots of the same.

with default interval

with normal_check_interval 30


PS: One more thing i want to tell, whenever i reschedule the check manually, some data comes into the graph, please see below the screen-shot of it.

Upon creation, rrds are specified with a minimum necessary amount of actual data over a specified time frame. If the percentage of actual returned data is beneath the percentage threshold over the specified time, rrdtool considers this block of data as "bad". There is not a good solution to this problem as of yet, as any changes to the rrd creation template will be global.

Thank you abrist,

It means as of now we can't get graphs for services with hourly or non global check interval. :(

Can you please provide me some good reference links so that i can understand the things more closely.
