If you are running XP then try running the Performance monitor. Programs ->
Run -> perfmon. You can select which parameters to continuously monitor and
importantly, it allows scheduled logging to a file - this may help isolate
your problems. It may also show regular background operations you were not
aware off.

I tend to monitor %processor idle time and %logical disk idle time. Even
when recording data and running MSGDM to "catch-up" on the previous day, my
% logical disk idle time = 86% (so its not stressed) and my processor is
idle about 15% of the time (so it's not on a limit). I run a fairly high
performance single PC set-up and rarely suffer lost segments even when using
intensive programs like Photoshop.

Cheers
Roger

It's in the post. The evidence would be in trying to correlate the
segment loss with the house-keeping activity of the MSG Data
Manager. Unfortunately, that isn't logged, but happens at 238
minute intervals, I believe.

However using the computer for MSGAnimator, internet, mail and
odds and ends increases segment loss quite considerably, although
certain uses make losses much worse than others.

Anything that will help towards the understanding of what exactly is
required for low segment loss would very much be appreciated. High
CPU load is definitely one thing. High disk load (e.g. asking
Explorer to display a folder of 1000 files) is bad. Network I/O
seems to be OK, perhaps the network card throttles the total
activity to a reasonable level? Possibly, heavy use of the TCP/IP
stack causes some segment loss.

Unfortunately I have to continue using my computer for more than
MSG.

.. as do many people. Being able to run on a single PC would enable
more people to enjoy the hobby so is something we should work
towards. Right now, if you get a second PC, nothing fancy
500MHz/256MB, that's one solution using your existing PC for
everything except the DVB card and Tellique software. Making your
single main PC 2GHz/1GB is another possible solution. Others will
have their own "single PC" configurations, and it would be good to
hear from them.

David

David, I would very much like to try a beta copy. I have spent some of the
last 36 hours attempting to try and establish when and under what conditions
I am losing segments -- not easy. I have found however that there has been a
slow improvement since Xmas day ( computer off all day for MSG ) and if I
leave the computer running only for MSG segment loss is down to about an
average of less than 10 in about 13/14 hours. However using the computer for
MSGAnimator, internet, mail and odds and ends increases segment loss quite
considerably, although certain uses make losses much worse than others.
Unfortunately I have to continue using my computer for more than MSG.
The strange thing is that when I started out with MSG over 3 months ago,
this present scenario is what I expected using only one fairly low spec.
computer, but in fact the first 3 months were the complete opposite, with
totally trouble free running -- the fun of computers !!

I very much appreciate your continuing efforts to help/resolve the problem I
and others have re segment loss.

Regards

Ian.

Ian,

It does occur to me that sometimes disk-intensive operations may
interfere with the Tellique software, just as CPU-intensive
operations might. It also occurs to me that during a spell of
operation, over some weeks or months say, you will build up more
files, and may therefore be more susceptible to such problems. This
is on a system where you have both the Tellique and the MSG Data
Manager software running.

Since 17/12/03 I have not added/amended any program not even updated
Norton.
Strangely from about 8.30 to 17.00 I lost about 30 HRIT segments today but
from 17.00 to 21.15 only 1.

Thanks again.

Ian,

Did you install a new version of (for example) my software after the
17th?

Have you checked the Tellique log file in detail around the time of
a segment loss? Perhaps it is trying to tell you something? A few
of us run with the verbose logging set which does give quite a lot
of information (but may slightly increase the missing segment
rate). In recv.ini:

[logging]

log_file_size=1000000
log_file_number=30
log_level=verbose

I will certainlty have log files going back a day or two if you want
to check. Name a time period (say 1 minute either side of a loss)
and I could e-mail you my log file for the same period...

Cheers,
David

Thanks for the mail James and detailed suggestions. I have looked at a
number of things and all appear to be ok. My last day with no segment loss
problems was 17/12/03 and I did roll back using restore but to no avail. The
DVB card is on IRQ 11 and shared with NVIDIA. One thing I haven't tried
though is disabling Norton Internet Security and Norton AntiVirus, might be
worth a try.
CPU usage varies greatly between about 5% and 100 % and I know that using
one fairly low spec computer is pushing things to the limit, but
nevertheless it does not explain the sudden change ( Athlon 1200, 768mb ram,
40Gb 7200 drive and 32mb NVIDIA graphics )
It is really very difficult with so many variables, can only hope that the
problem disappears as quickly as it appeared but I am not holding my breath.

Thanks again for your help and a Happy Xmas to you and your family.

Regards

Ian.

Thanks again.
Ian I don't suppose there has been a loss of IRQ steering anywhere down the line? Does the DVB card have it's own? Any change in MB BIOS settings for the IRQ's?

Have you lost any RAM, installed any TV s/ware for the card?

No viruses, trojans, or firewalls checking files or virus scanners wanting to do the same?

Any s/ware updates you have performed - is it possible to roll back to a month when things were OK.

Using the system analysis tool how much CPU usage do you get, and what shows up in the networking.

It sure is annoying - and I'd love to help, but it looks like you are trying everything.

Cheers,

Re: Segment Loss

Ian S Deans <ian@...>
 

David, many thanks for your detailed reply to my missing segment problem.
My FSY files were all removed when I reloaded Tellique and I am fairly
certain that signal level etc is not a problem. I am using the new version
DVB card and actually had additional fan fitted about 4 weeks ago when the
chip fan packed up and had to be replaced.
I note that you also recommend the change in "rec ini" to allow buffered
writing of log data, but that change has caused me even more problems (
trebled the segment loss ) so I have reverted back to the old setting ---
strange.
I have now resigned myself to accepting that there is little more I can do.
For looking at individual images it is not a problem with the vast amount of
data we get, but unfortunately animations which in my opinion are an
important part of MSG are now mostly spoiled.

Many thanks again for your help and as others have mentioned for all your
superb support throughout the year.

Merry Xmas to you and Cecilia.

Ian

Thanks.
Ian,

First: are you sure it isn't signal level or QRM related.

Second: I would also recommend making the change. It should read:

[locations]
log_file=>>recv.log

I have made this change on both of my systems.

Third: In a Eumetsat install, they appear to reduce the size of the
FSY files, the database used by the program. I have been advised
that this should be 250MB. Check the total size of the files in:

C:&#92;Tellique&#92;receiving&#92;tmp

On one system I have 2 x 100MB files and 1 26MB file, on the other 2
x 100 MB and 1 x 18MB. Arne van Belle is a great believer in
deleteing these files when you restart the Tellique client. It is
possible that you can't defrag these files (as they may be held
open) so letting the program recreate them is a good idea! My own
files seem to have increased to this very high level at the start of
my recent complete outage due to snow.

I have been advised:

"If you see "File system full" messages in the log files, increase
the parameter: "file_database_size=" in the recv.ini file.

"If you can't find this parameter, the default value of 250 MB is
used. This value should be sufficient even if you receive all data
from Eumetcast."


Other suggestions: card cooling - is it the 2.3 or 2.6B version you
have? Tighten connections? Any better after restarting the PC from
a mains-off reboot? Search back over this forum?
Bit clutching at straws, I'm afraid.


Cheers,
David

Multiple data folders for the Tellique software

David J Taylor GM8ARV 🏴󠁧󠁒󠁳󠁣󠁴󠁿 πŸ‡ͺπŸ‡Ί
 

Folks,

There seems to be some information floating round from somewhere (I
am not sure from where, but it is in Bepi's configuration guide)
that the Tellique software should be configured with two separate
folders to receive the channel 2 (HRIT) and channel 3 (LRIT) data.
Something like this:

(1) N:&#92;Tellique&#92;received&#92;
(2) N:&#92;Tellique&#92;received&#92;Data Channel 2&#92;
(3) N:&#92;Tellique&#92;received&#92;Data Channel 3&#92;

As you will know, the current MSG Data Manager does not support this
configuration, although it could be made to support it if people
wanted to do so (in addition to the present single folder). As far
as I can check, the current Eumetsat installation CD provides
a "recv-channel.ini" file that puts all the data into one folder.
Perhaps someone could confirm this?

Apart from the one person who has asked me off-list, is there anyone
who feels that I should support scanning of all the directories
[i.e. (1) (2) and (3) above], if (1) is specified? I am quite happy
to do so, if you feel it is needed.

Thanks,
David


DVB-s card

I use a PC and Windows XP .

Is it possible to have access to MSG-1 datas with this card and if yes how can I do ?

Re APT - many years left

Lawrence <lawrence@...>
 

next decade. Cut your teeth on a.p.t. if you wish, though currently,
setting up an MSG-1 system could be cheaper.

best wishes and welcome

Lawrence Harris
Lawrence,

How could you?

Yes, APT from NOAA's will be with us till at least 2010 - all you need is a
RIG RX2, a sound card and WXSAT. Can't get much cheaper than that!

Hello John

In most cases I would expect a newcomer to want to buy a completed
receiver, rather than a kit. This alone makes it more expensive than the
MSG-1 option - assuming that the person already has a suitable spec
computer. Hopefully, a newcomer would read up on the options and devote
enough money to set up a proper system over a period of time.

If the person is ready to do construction, they are in a different
ball-park.

Lawrence
