Re: Telnet Output

Here is what I would try first:

# Here be ***UNTESTED*** code
my %snr;
while ( my $line = shift @lines ) {
    chomp $line;
    if ( $line =~ m/SNR:\s+(\d+)\s+(\d+)/ ) {
        ( $snr{up}, $snr{down} ) = ( $1, $2 );
        last;
    }
}
print q{Upstream_SNR:}, $snr{up}, 
        q{ }, 
        q{Downstream_SNR:}, $snr{down},
        qq{\n};

(The print based on a quick glance at Chapter 11 of the Cacti manual.)

Hope that helps.

Fix typo in code (missing underscore in second field name).

Thanks for the reply. How would it work if I had multiple SNRs? For examples `SNR Margin 60 60 (US0,--) 0.1 dB SNR Margin 61 53 (US1,DS1) 0.1 dB SNR Margin 62 50 (US2,DS2) 0.1 dB SNR Margin 0 N/A (US3,DS3) 0.1 dB SNR Margin 0 N/A (US4,DS4) 0.1 dB` [download]	[reply] [d/l]

But I need some sort of checking as some of the SNRs will report 0 or N/A. Need it to report 0 instead of N/A.	[reply] [d/l]
