Possible Traffic Manager Bug (and feature request)

[fwfreak]

Specs:
ASUS RT-68U
Merlin FW 376.45

My router had been up for approximately 56 days straight. I rebooted it to troubleshoot an ISP problem. before reboot for the month of Oct it showed 126GB of total usage. After reboot all the data usage for Oct had been wiped and most of September as well.

I have configured it to store this data on a usb drive mounted at /mnt/DATA and configured it to save the data hourly. I know in the past reboots have lost me a small bit of usage data, but not an entire month plus.

Which leads me to two questions:

1) Would it be possible to force this data to be committed to the external storage when the reboot button is pressed in the UI?

2) Can we get a smaller interval than an hour? like 5 - 15 min time range? Is there a manual way to commit this data?

Thanks!

The data does get committed to disk during router shutdown, in addition to every hour. What happened in your case is most likely that the router was unable to access the database for the past 6 weeks, so all the data was being written in RAM rather than to disk. Look your system log for any error message regarding accessing the database.

2) Can we get a smaller interval than an hour? like 5 - 15 min time range? Is there a manual way to commit this data?

No, as this is excessive, and would lead to other problems.

Unfortunately the log doesn't go back that far due to miniupnpd and dnsmasqd spam in the log. Is there a manual process we can login and execute to ensure this data in RAM isn't lost?

You could check the modification date of the data file itself on your USB disk.
