Post by Box293 » Tue Jun 07, 2016 7:39 pm Just delete the .rrd files that are not working in /usr/local/nagios/share/perfdata/host_name/_HOST_.rrd This will lose any historical data, but is the simplest way to fix the issue. The screenshot provided explains that there are 4 datasources in the RRD f...

It took a lot of digging through the perfdata debugging logs, but I did find an error that seems to appear for each of the hosts in the one hostgroup that does not diplay perf graphs or state history. Here it is. error.PNG I see this error only on the hosts in the hostgroup that is having trouble wi...

Thanks for the reply Box293- I did follow the KB article to enable debugging on both perfdata and npcd. I was expecting to see recurring errors or timeouts or something. I didn't. Here is the screenshot of one of the hosts advanced tab. Mason,Host.PNG I ran the command you suggested. Here is the out...

I also did a tail on perfdata and npcd. I am not getting even close to threshold and I did not see any errors in the perfdata.

Thanks Imiltchev for the document. So I checked my other host groups that have performance data enabled and lo and behold all of their perf graphs are showing AND their state history shows up. Only the one host group has stopped showing this data. I did change the check_ping argument and check inter...

One more piece of information that might be useful. I did create a new server key to install a new security certificate so would could use the name and domain we wanted in the url over 443. These were configured and installed on the same day that the last perf graphs showed up. Not sure why that wou...

Also which backups should I try to restore? I have figured out which days the performance graphs were working and the state history was working, but which database do I restore and in what order? There are MySQL , Nagios , nagiosql , nagiosxi and test backups from which I could restore in /store/bac...

Here is the tail on the sql log since running the repair script.

I ran the database repair scripts successfully. Although the only errors in the MySQL logs are from 5-22-16. The performance graphs and the state history were working after that, but have since stopped working. I just noticed today that the state history reports only go up to a certain date and then...
