graphs disappeared after setting correct time

Post by t3hflame »

Hi all,
I'm currently evaluating NagiosXI and after updating the correct timezone/date the graphs disappeared.

What logs I can check to see what's going on?

Thanks. :)

Yeah, I think RRDtool gets confused when the time jumps around. Depending on which way it changed, I think either the graphs will come back on their own, or you'll have to manually delete the files in /usr/local/nagios/share/perfdata/* and then they'll regenerate.

Thanks for your help, mate.
I've deleted the files/folders under /usr/local/nagios/share/perfdata/ .

I'll wait the graphs to show up again.

EDIT:

Looks like it's not coming back.
Still the same issue.

Any ideas?

To clarify rrd uses GMT time, so adjusting the clock's time zone or for daylight savings in Linux will have no effect. Keep in mind that Windows will change the clock, keeping it correct for the current time zone and day of year.

rrd tool used to depend on receiving newer information. Adjusting physical time backwards will result in rrd tool dropping results until time once again starts moving forwards.

As for your problem there should have been no relation to the graphs and the currently configured time zone, please provide more information.

Performance graphs can be a bit finicky at times. I'd try the solutions listed here first.

Ok, it's working again.
Just did a reset to security credentials.

Thank you very much!
