    @mcury Different issue. As I stated, Status -> Monitoring works fine for me. Also RRD Summary worked fine for years until I reinstalled pfSense. I wonder if there is a longer delay for showing these data.

      Hm, ok, so yours is working. Thought that this could be related.
      Somehow I didn't read your last sentence.. 😪

      dead on arrival, nowhere to be found.

        It wasn't that long ago that I logged in one morning and found many package updates. It was mentioned in the forum that they were all changes to the copyright date (to 2021). Maybe a bit got flipped in one of the files by accident.

          It looks like internally the package calls the following command:

          /usr/local/www: /usr/local/bin/rrdtool fetch /var/db/rrd/wan-traffic.rrd AVERAGE -r 86400 -s "-10y" -e "now"
          

          When I try this, rrdtool returns only NaN values. This is probably the reason why no data volume is computed, but I do not know why. Can anyone help please?

            In the hope that more information gets me help more easily, I executed

            /usr/local/bin/rrdtool fetch /var/db/rrd/wan-traffic.rrd AVERAGE
            

            and received output for which I quote the last lines

            1613774400: nan nan nan nan nan nan nan nan
            

            The first value is advancing and seems to be the time. I find that the entries with the most recent time tag are always NaN, and this seems to cause the issue. The values get filled in with the next time step, so this seems to be a synchronization issue. Any advice?

              I guess this is magic? I have no idea what I did.

                @provels Lucky duck! I am glad it's working for you.

                I am wondering if I do not have enough data yet. The NaN's rrdtool is returning for me indicate unknown data when averaged at the day level. I am inclined to just let it sit for a few days or even a month. rrdtool is clearly working and so was the package prior to reinstall.

                  I did reinstall the RRD package yesterday (no uninstall). Maybe that did it. But I'm sure the data had been missing for some time. I messed with the command line you posted yesterday (-1y, -1d, -1h, etc.) but I didn't understand the data returned. The 86400 is the number of minutes in 2 days, but I don't know the significance in the CL. Where did you find the command? Going to read up some here: man rrdtool
                  Have to admit, when it's working it's quite accurate. Stats from Comcast and pfSense below.

                    I tried re-installing yesterday as well as deleting the RRD data, neither helped. I really think I just need to give it more time to accumulate data.

                    The rrdtool call is in the php code for the web page. This is stored in /usr/local/www/status_rrd_summary.php. There are multiple calls because rrd tool is finicky about the phasing of the resolution wrt the start and end time. The command I listed is the first call which seems to just get an inventory of the data. The 86400 is the number of seconds in a day, so it is requesting daily averages. The are subsequent computations to set the boundaries correctly for the computation.

                    I too found that the calculations of the RRD Summary package match the numbers predicted by my internet provider within a few percent.

                      Only other thing I can think of is making sure you're on the right upgrade repository, but I don't think the package has been modified for years so probably doesn't matter.

                        PS - I guess even though it's started recording data again, all the data between when in broke on 2/4 and started again yesterday was not logged. I only show 95 GB for this month where my provider shows 440 GB. Post back again if you start getting data.

                          As suspected, 3 days later, the first data have shown up now. So it really just needed more data to start working. Nothing broken here.

                            Oddly, my RRD has reverted to the data ending 2/4 as before. Reinstalled, un/reinstalled, no better. Go figure. Probably should start another thread.

                              @provels New thread may be appropriate as I marked this one as solved.

                              Check if your Status -> Monitoring is working and showing current data. This runs off the same dataset.

                              Other than that you can use the rrdtool command above to check that the database is filling. There is a task associated with filling the database; make sure this is running. During debugging you can turn unix time into date/time format using "date -r" function.

                              If nothing works you can try deleting the database and start over. Maybe it is corrupted.

                              Good luck.
