Performance graphs

Question

Hi all,&nbsp;I am curious as to why I now have no data in my performance graphs irrespective of the period I select. Any ideas???&nbsp;I had an NTP issue a few days ago which set my clock back to 1st Jan 2003 but that has been corrected and shouldn't impact this data AFAIK.&nbsp;Is there a process I should verify is running via the console? Is there something I should restart?&nbsp;Thanks...

You've discovered a bug in the handling of a rewound clock by the thread that updates the graph data. &nbsp;If you don't reboot (or restart readynasd), you won't see any graphs for the next 14 years.&nbsp;:smileyhappy: &nbsp;The underlying issue here will be fixed in 6.7.5.

Just to add, these were the logs I see after the clock was set in the past by NTP.

Jan 01 00:02:37 DESPAIR readynasd[5804]: UpdateRRDVolume failed: ERROR: /run/readynasd/stats/volume_data_int.rrd: illegal attempt to update using time 1041379357 when last update time is 1496132602 (minimum one second step)

The time later corrected itself but maybe a process has stopped or some action needs to be taken.

I think that's just a side effect of the bad time. &nbsp;If you google, you'll see several other reports of this after NTP messes up.

I know but how do I get my graphs back... I'm thinking deleting the .rrd files will suffice but I'm keen to get feedback.&nbsp;

Thanks...&nbsp;How can I safely restart readynasd on a running system without impact? I have SSH access.&nbsp;Something else I've noticed too is that following each upgrade the historic data on the graphs is lost too, although this may be intentional.
