Eric,

A quick question if you don't mind?  :graduate:

Are the average errors for FEC errors cumulative?

      Per second   Per minute   Per hour     Per day

CRC   Up   0      0.04      2.24      53.7   
   Down   0      0.01      0.56      13.4   

FEC   Up   0      0      0      0   
   Down   109896      6593761      395625632      9495014400   

HEC   Up   0      0      0      0   
   Down   0      0      0      0   

ES   Up   0      0.04      2.24      53.7   
   Down   0      0      0.19      4.47

Colin,

No, they're supposed to be the same as the other items on that page, i.e. the average rates over a period of up to 24 hours. The actual period which applies is shown above the table. The FEC per-minute values in the table should broadly correspond with the FEC per minute graph for the same period.

So the values you have are completely wrong, and it looks as though you've uncovered a bug. Can I ask that you press the button "Reset values" on that page, and see how the values develop when starting afresh?

Sure.  what would you like me to look out for?

FYI:
Since Link time = 22 hours 6 min 51 sec
FEC:      509819      189 <--- bad enough as it is!!  :) ;)
CRC:      185      63
ES:      3      61
SES:      0      0
UAS:      0      0
LOS:      0      0
LOF:      0      0     

[EDIT] Not sure which way around you are calculating it Eric, but atm after 15mins, it seems that day (number)/24=hour, hour/60=mins, mins/60=secs, so these are self-consistent, and, it seems that the day number is not (yet at least) accumulating, in that the figure for 1 min's day sample (2034704) can be less than the previous one (2095496).  ???
However, by the same token, the FEC graphs are currently showing minute-by-minute DS rates in the 300-10,000/min on the logarithmic scale. While the modem is reporting:
Since Link time = 22 hours 38 min 51 sec
FEC:      573967      194

I'd just like to see if it continues to report crazy values for average FECs, or if the values settle down to sensible levels. You'll need to run it for an hour or so after the reset to collect enough data to be meaningful.

Sorry for the delay Eric.  I was waiting to see if perhaps when the 24hr period rolled over the count wasn't reset properly or something.  The good news is that it looks OK, i.e. it doesn't have astronomical figures anymore, just big ones. So maybe they really were as high as that - I do have other output from BE's programs that showed that FEC rates reached something like 10^7/min for about 12hrs on 09/06, and at the point I posted the question, DSL stats had been running for 4-5 days over that time.
I do still have a bit of a niggle at the back of my mind though, as somehow (it may just be me again) I can't see to reconcile the FEC/min graphs & averages with what is recorded in the telnet stats for e.g. the 15 min periods. Is there some way we can snapshot those 3 things together for you to see if I'm just barking again or not?
Cheers,Colin

Thanks for the information, Colin. I'll have a think about ways of reconciling those different views of the data, although it will involve some head scratching. :)

I only meant - as a diagnostic - not as a facility, if I gave you the wrong impression.  I'm not sure yet that anything's wrong, it just doesn't seem right.  SoI thought if you could see your own telnetlog stats data, at the same time as snapshots of the FEC rate and averages, it might tell us if they are the same or not?

I'll see what I can do. I suppose that if I set the sampling period to 15 minutes, then the points plotted on the graph will correspond directly with 15-minute periods, and it may be possible to relate these values to the 15-minute periods reported in the telnet stats.

What a good idea - I'll try that myself!  ;D

Unfortunately you won't be able to with the version you've got, because the sampling period is limited to 10 minutes. This is a purely arbitrary limit, and I've set it higher for test purposes. I'll increase the limit in the next version.

I set my sampling period to 15 minutes, and by trial and error I roughly aligned the sample times with the 15 minute periods in the router stats. I read the downstream values on the FEC/minute graph and multiplied them 15, to compare with the values reported by the router in its 'Latest 15 minutes' section:

Code: [Select]
Downstream FEC rates
--------------------

      Graph                    Stats
      -----                    -----
   Per minute   Per 15 min      Latest 15 min
   ----------   ----------      -------------
Time

10:35   6.0      90         89
10:50   28.5      427         449
11:05   16.0      240         215
11:20   4.0      60         56
11:35   8.0      120         124
11:50   9.0      135         134
12:05   15.0      225         227
12:20   21.5      322         321

Allowing for the fact that the 15 minute periods weren't perfectly aligned, there's very good correlation, so I'm reasonably confident that the graph is reporting correct values.

I'm still thinking about how best to validate the averages.

(Sorry that the formatting isn't very good)

Thanks Eric, that's pretty conclusive. :thumbs:

I guess it was harder for me to see that properly when the numbers were so big and the periods not sufficiently aligned.  Apologies for doubting it, but this gives me more confidence to believe what I am seeing (but hoperfully nothing like 10^7/min again!)

Thanks Colin. I'd still like to validate the averages, and I think I can do that, but it will take 24 hours. :)
