Re: [hylafax-users] ratio DONE/FAILED

["Andrew Rinaldi" <andrew.rinaldi@xxxxxxxxxxxx>]

And here's the data from Lee's posting to the hylafax-users@xxxxxxxxxxx
mailing list in October 2006.

"
Realize that I calculate error rates based on errors per pages sent.  

There doesn't seem to be a perfectly fair way to calculate those statistics
so that a single repeated problem for a single destination on a one-page fax
doesn't count equal to a successful 200-page fax.

I have a suspicion that the slightly higher rates on the Mainpine
implementations is a result of V.34-Fax support... which is young,
comparatively speaking.  None of the customers complain, in any case.

It's an 8-port ISI5634PCI with firmware 4.28d (which may be old, but it
works for me).  I'm currently using Linux kernel 2.4.30 and HylaFAX+
4.3.0.11 on it.  It's receive-only, and in the last 78,829 pages of fax
there were only 313 session failures (0.4%) which is about normal for the
production servers that I maintain.  For comparision purposes here is a list
of receive statistics for some systems that I maintain with
multiport-modems... modem card, total pages, failures, and calculated
failure rate (per-page).  (Realize, too, that most of the receive failures
are going to be caused by a sender-initiated abortion... so
*some* level of errors must be expected since there is not a standardized
way for a sender-initiated abortion to occur.)

Kernel 2.4.20 Comtrol RocketModem II V2.300L-V90_2M_DLS_RAM: 38,178 pages -
60 failures (0.2%)
Kernel 2.4.20 Comtrol RocketModem (ISA) V2.200G-V34_ACF_DS1: 38,207 pages -
101 failures (0.3%)
Kernel 2.4.20 Comtrol RocketModem II V2.300L-V90_2M_DLS_RAM: 45,858 pages -
99 failures (0.2%)
Kernel 2.4.29 Comtrol RocketModem II V2.300L-V90_2M_DLS_RAM: 32,943 pages -
78 failures (0.2%)
Kernel 2.6.8 Mainpine RockForce OCTO+ I03.04.02 (0026SD): 34,095 pages - 319
failures (0.9%)
Kernel 2.4.28 Comtrol RocketModem II V2.300L-V90_2M_DLS_RAM: 50,534 pages -
98 failures (0.2%)
Kernel 2.4.28 Digi AccelePort RAS 4 V20040915-K56_DS (Patton driver): 27,257
pages - 97 failures (0.6%)
Kernel 2.4.31 Comtrol RocketModem II V2.300L-V90_2M_DLS_RAM: 33,376 pages -
70 failures (0.2%)
Kernel 2.4.30 Comtrol RocketModem II V2.300L-V90_2M_DLS_RAM: 44,560 pages -
75 failures (0.2%)
Kernel 2.6.10 Mainpine RockForce QUATRO+ I03.04.02 (0026SD): 9,890 pages -
57 failures (0.6%)
Kernel 2.4.30 Patton 2977 PT1 V20040915-K56_DS: 29,933 pages - 271 failures
(0.9%)

(So 0.4% is right in-there as far as statistics go.  However, one should not
use these figures too seriously... because it's fairly easy for one drunk
fax sender who keeps pressing the "stop" button to generate a dozen failures
all in a 30-minute span... and in those systems that run higher rates of
errors than the others, that's what I tend to see: one sender that
repeatedly fouls up the statistics on a few occassions.  And even at that,
1% error rate is historically a very good score - see the archives to see
people proclaiming 5% error rates as "good".)

we're running a sending only environment on Eicon Diva. Usage: Media 
releases, mainly financial content, average 2 pages a destination. 
Target groups: media, banks...

I took some quick stats from the DB:

OUT, faxes:    17'226 (different destinations: 2'215)
SENT:          14'537
FAIL:           2'682

FAIL includes all possibilities of errors (as defined by you), incl. 
BUSY (retry: 7 times).
