 Posted: Sat Jul 30, 2005 9:28 pm Post subject: Cablemodem template & perl script |
 |
|
This script reads the results of an http page grab and populates the data sources with the values.
The script is set to run on an RCA modem's status page which is located here: http://192.168.100.1/diagnostics_body.html . This is my page location. Yours may differ. You should look at http://192.168.100.1 and find the actual address of yours. This goes in line 7 of the perl script.
SNMP would have been useful but it is turned off aytime the modem gets a sync. I think the ISP uses snmp to configure the modems.
I have attached the script and xml template. Enjoy!
You will have to edit the perl script to match your page.
| Code: | #!/usr/bin/perl
use warnings;
use strict;
use LWP::Simple;
my $httpaddr = "http://192.168.100.1/diagnostics_body.html";
my %data;
my @keys = qw(DownFreq DownSNR DownPower UpFreq UpPower);
my $content = LWP::Simple::get($httpaddr) or die "Couldn't get it!";
$content =~ s/\ |\n//g;
# regex in html source order
if ($content =~ /Acquired at (\d+\.\d)\d+ MHz/) { $data{DownFreq} = $1; }
if ($content =~ /SNR: (.+?) dB/) { $data{DownSNR} = $1; }
if ($content =~ /Frequency: (.+?) MHz/) { $data{DownPower} = $1; }
if ($content =~ /Received Signal Strength: (.+?) dBmV/) { $data{UpFreq} = $1; }
if ($content =~ /Power Level: (.+?) dBmV/) { $data{UpPower} = $1; }
for (@keys) {
print "$_:" . $data{$_} . " ";
}
print "\n"; |

Just and FYI
QAM is the modems modulation profile.
Frequency very rarley changes.
Your downstream power level appears to be graphing improperly.
Oh, and BTW, if that is your cable modem, and your upstream is 61dbvm, you may want to call the cable company and see about getting a service call, chances are you are currrently or will be dropping offline.
Good; thoughtful; and well written script otherwise

Thanks Alives works well for me, although there are never any error stats - is that correct? Do they only actually appear when the modem is in an error state?

| well the script just does a straight html scrape to get the data... you should be able to edit the script and chane it to what your page looks like. standard regex pulls.

Was bored at work so I modified the script to work with my Surfboard SB5100 modem. Use the same template as the other surfboard modem above.

| Loki: Your problem is likely the same I experienced with Bug 816. There is not a fix for it yet, that I'm aware of.
