Problem Graphing Host with 4hr Check Interval

[mrochelle]

Actually they don't appear to be since the check interval is set for 240 mins and the updates in the rrd is every 6 hours?

I want to see your configuration snapshot tarball, lets move this request to the ticketing system as most tarballs include fairly sensitive information.

Could you open a ticket by sending an email to [email protected]
Reference this thread by link and attach your most recent working configuration snapshot tarball to the email.
See you there.

rrdtool dump /usr/local/nagios/share/perfdata/ET_50015/_HOST_.rrd
<!-- 2013-04-30 01:00:00 CDT / 1367301600 --> <row><v> NaN </v></row>

Actually running this command is only showing you the items in the 6 hour compression. What we really need to run is the following

Code: Select all

rrdtool fetch /usr/local/nagios/share/perfdata/ET_50015/_HOST_.rrd AVERAGE|grep -v nan

Following is the output of the last 10 lines:
1367372400: 1.0000000000e+00
1367372460: 1.0000000000e+00

This actually seems correct. The graph isn't going to fill in until the next check as it doesn't have data for the time period. When the next check is run (or if you manually execute the check) it should fill the empty area with an average.

[mrochelle]

No, the next period has passed and no data. As long as the check interval remains at 240 minutes, no graph will be generated. I ran the same command on several other hosts that have been at the 240 minutes interval for over several weeks. Following is the output.
rrdtool fetch /usr/local/nagios/share/perfdata/ET_77216/_HOST_.rrd AVERAGE|grep -v nan
1

rrdtool fetch /usr/local/nagios/share/perfdata/ET_77024/_HOST_.rrd AVERAGE|grep -v nan
1

rrdtool fetch /usr/local/nagios/share/perfdata/ET_862507/_HOST_.rrd AVERAGE|grep -v nan
1

None of the indicated Hosts show any data on the graph.

We received the snapshot you went and will continue communicating via email. I am locking this thread.
