Problem Graphing Host with 4hr Check Interval

Nagios XI Version : 2012R1.6
Nagios Server 2.6.32-279.11.1.el6.x86_64 x86_64
CentOS release 6.3 (Final)
Gnome is not installed
I'm having a problem getting the graphs to display for a host network device that we only need to monitor once every 4 hours. From the advanced tab the performance data is captured.
4Hr_Host_Perf_tab.PNG
Since all my graphing for a number of other hosts and services work fine, the only difference is the check_interval is 240, I'm guessing I may have exceeded some default limit or need to modify some graph configuration parameter?
Thanks, Marcus

What is the full command for your check? The performance data looks suspect . . .

/usr/local/nagios/libexec/check_device.pl --device $HOSTALIAS$ --hostaddr xxx.xxx.xxx.xxx
The performance data is correct. 1 means OK the check is good. 0 of course means the check failed.

How long has this check been collecting data\running for? Its less about the check interval that you have and more that graph explorer requires a certain amount of data before it creates meaningful graphs. This is also the same with capacity planning. At once every 4 hours, it may take a few days before it has sufficient data to create a graph.

I believe you may have a point. The performance data was just turned on two days ago. I've noticed that some of the hosts where I have generated several immediate checks have started graphing. I will monitor over the next few days to check results.

Great. Let us know how the graphs turn out.

Well, it has been over a week now and we are not generating reports. I believe there is probably some tweeking required. Suggestions?

Could you post the output of (replace <hostname> with the hostname or ip of the host in question):
Code: Select all
cat /usr/local/nagios/var/perfdata.log | grep <hostname>
tail -25 /usr/local/nagios/var/npcd.log

also, can you verify some permissions
Code: Select all
ls -ld /usr/local/nagios/share/perfdata
And the following replacing <HOSTNAME> with this hosts name
Code: Select all
ls -l /usr/local/nagios/share/perfdata/<HOSTNAME>
