We're running analog on an NT server and it works great, with the sole problem
that execution times vary a great deal. It is particularly obvious with one
domain, which often will run for hours at a time. (Sometimes it seems never to
finish.) I started making a note of the times, and here's the last
week-and-a-bit:
Monday 6 Sept: 3 minutes 6 seconds
Tuesday 7 Sept: 528 minutes 33 seconds
Wednesday 8 Sept: 214 minutes 18 seconds
Thursday 9 Sept: 210 minutes 29 seconds
Friday 10 Sept: 0 minutes 19 seconds
Monday 13 Sept: 199 minutes 47 seconds
... some discrepancy ;-).
They're not huge logs: we don't log image requests, so the domain has had about
175,000 page requests over a 15-month period. (That does appear to be the
busiest domain though, so probably stands out; other domains seem to show
similarly erratic execution times.)
The problem is not that multiple copies of analog are running: a scheduled task
warns me if the lockfile exists. Analog is doing DNS lookups, although older
logfiles are translated by DNSTran on a neighbouring Linux box, so as not to do
lookups.
I've yet to see any real errors reported by Analog. The domain's .cfg file
includes these entries:
DEBUG dsc
WARNINGS on
I'm writing an ERRFILE; it has no interesting information, just a single warning
of possibly-overlapping logfiles, and a note every 10,000 entries. (It would be
nice if this note included a timestamp, BTW.)
What's doubly weird about these execution times is that just before the log is
run, an equivalent report is prepared for the Report Magic program... so I would
have thought the DNS lookups shouldn't affect things at all. (It's just been
done for the Report Magic data log.)
(Is it possible to have two different output files -- one as HTML, another as
computer -- from the same config file?)
Any suggestions as to the reason for slow execution would be very welcome! Using
v3.32 on Win NT (it's not a new problem; it's been like this since as least
v3.2).
Thanks,
Matt
