Graphs not saving on reboot

Running RB532A. When I reboot, the graphs are all empty, even, though the “save to disk” option is checked. And yes, I am using an NTP server and it is synchronized.

Anyone have any ideas? I’d really like to be able to keep my stats so I can monitor my usage, but this makes it really hard.

Thanks,

router is storing those data every 5 minutes. Maybe it rebooted to early - didn’t save it.

This router ran for 4 months. I did a few reboots in there and the graphs were fine. Then I did an upgrade of the ROS and rebooted and the graphs were gone.. I thought maybe they just didn’t save between reboots. Then it ran for another 3 months, in which time I had a few more reboots and the graphs were fine, but then I did another reboot last week and the graphs were gone again.

Any ideas?

Thanks,
Joe

What version is installed on the RouterBOARD now ?
Simple ‘system reboot’ should not cause such issue, graphs should be stored (if time is set correctly and data is being saved to hard drive).
If such old data about resource is vital for you, than you may try with external SNMP collector, that receives data from SNMP and stores on the independent location.

I have experienced the same as jcremin a couple of times on a 532 with 2.9.45. Several reboots and power outages over many weeks and the graphs are kept, then suddenly after a power outage they are gone.
I assume this should be well-known to you MT guys?
