logging SNR

I would like to log the SNR on a certain satellite channel. Does anyone here how to do that?
(without using the remote control and writing it down of course)

abu_ilya

I figured it out (even though it is not as elegant, it works)

wget -O - --user=root --password=dreambox http://192.168.1.3/xml/streaminfo |grep snr |cut -d '>' --fields 2 |cut -d '%' --fields 1

now I can use this command in a script to log the snr and make a nice graph of it

@ abu_ilya
It may seem like a stupid question
But is 192.168.1.3 the IP addr of you dreambox or PC.

Try something like this:

echo 'SNR, AGC, BER:' && wget -q -O - http://192.168.0.199/satFinder?|grep '<td align="center">'|sed -e 's/.*<td align="center">//' -e 's/<.*$//'

echo 'Time;SNR;AGC;BER'>ala2.csv
echo '' > ala0
echo '' > ala

while [ $i -le 20 ]
do
  uptime | sed '/ /s///g'|sed 's/up.*/;/' >> ala0 
  wget -q -O - http://192.168.0.199/satFinder?|grep '<td align="center">'|sed -e 's/.*<td align="center">//' -e 's/<.*$/;/' >> ala0

  cat ala0 | tr -d '\n' >> ala
  echo '' >> ala
  i=`expr $i + 1`
  echo ''> ala0
  sleep 5s
done

sed -e 's/%//g' -e 's/;$//g' ala >> ala2.csv
more ala2.csv

As the result you will get the Excel file "ala2.csv" with the following columns:
"Time ---- SNR ---- AGC ---- BER"

try this command from the shell:

code:
1:	root@dm600pvr:~> wget -q -O - http://root:dreambox@192.168.0.199/xml/streaminfo

or from your browser:

code:
1:	http://192.168.0.199/xml/streaminfo

and tell if it is working.
Of course type your Dream IP, and your password.

So, I see you don't have the "satFinder" part.

In this case, try command:

code:
1:	wget -q -O - http://root:root@192.168.0.199/satFinder?

If it is working, please attach the file "test_html.txt", after execution of this command:

code:
1:	wget -q -O - http://root:root@192.168.0.199/satFinder?>test_html.txt

Optionally, you can use a browser, open the link:

code:
1:	http://192.168.0.199/satFinder?

and then attach source code of this page.

The next version I am testing at the moment, will be more universal and much more precise.

Strange!
On the first glimpse, the source of your "satFinder" page, seems to be exactly the same like mine.

And now sorry, simple but brutal question Augenzwinkern

.
Have you changed lines 17, 18:

code:
1: 2: 3:	# write your user name & password here use_er=root pass_d=root

on, for instance:

code:
1: 2:	use_er=root pass_d=dreambox

Without MY Dreambox IP and password, it wouldn't have even logged anything. I think I'll wait for the next version.

Tried this one on DM500 and DM7000.
This time there was no .csv file at all.
Maybe because it's not DM600?

Impossible.
The first 45 lines are exactly the same, like in the previous script,
so you should have, at least, the some results like before.

Had you changed propeties of the scrip file:

code:
1:	chmod 775 snr_snoop.sh

Do not think so.

Well I tried several times but all in vain. Could not believe it myself. I sincerely hope that somebody else will try it and say OK. But on my DM7000 or DM500, it simply would not work. One last thing, if I put back your previous script, I get the same results as before. Strange but true.Tx.
