[smokeping-users] graphing traceroutes possible?

[Russell Dwarshuis]

Since someone asked and others may want it, here's (more or less) the 
script I cobbled together to run traceroute on a slave and mtr on the 
master, then email the results when a smokeping loss trigger happens.  It 
will need customization for your environment but should get you started.

                                 -Russell Dwarshuis

------------------------------------------------------------
#!/usr/bin/perl

# this script would be run when smokeping detects some loss.  The
# smokeping trigger could look like:
#
# +highLossTwice
# type = loss
# pattern = >70%,>70%
# to = |/usr/local/smokeping/contrib/mtr_email.pl
# comment = 10 minutes of high loss

# this runs mtr on master and traceroute on a slave and emails results
# to an address hardcoded below.  It was a throw-away so I didn't spend
# any time making it user or developer friendly.

use Net::SMTP;
use English;

my ($name_of_alert,$target,$loss_pattern,$rtt_pattern,$hostname) = @ARGV;

# change smokeping host name to dotted quad IP address if it isn't one already
if ($hostname !~ /^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/) {
   ($name,$aliases,$addrtype,$length, at addrs)=gethostbyname($hostname);
   ($a,$b,$c,$d)=unpack("C4",$addrs[0]);
   $hostname="$a.$b.$c.$d";
}

if ($hostname !~ /^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/) {
   print "invalid IP address $hostname\n";
   exit;
}

push @mtr_results, "To: someonewhocares\@yourcompany.com\n";
push @mtr_results, "Subject: smokeping detected loss to $hostname\n";
push @mtr_results, "smokeping detected loss to $target.\n\n";
push @mtr_results, "mtr was then run on the smokeping host and the results 
were:\n";

open MTR, ("/usr/local/sbin/mtr --report --report-cycles 10 --no-dns $hostname |");
push @mtr_results, (<MTR>);
close MTR;

push @mtr_results, "\n\ntraceroute was then run on smokeping slave and the 
results were:\n";

# Now trying traceroute on slave via ssh
open SSH, ("/usr/bin/ssh -o 'UserKnownHostsFile /usr/local/smokeping/.ssh/KnownHosts' -i /usr/local/smokeping/.ssh/id_rsa slaveuser\@slave.smokeping.yourcompany.com /usr/sbin/traceroute -w 3 -m 10 $hostname |");
push @mtr_results,(<SSH>);
close SSH;

# send the email.
$smtp = Net::SMTP->new('mail.yourcompany.com', Timeout => 5);
$smtp->mail('smokeping at master.smokeping.yourcompany.com');
$smtp->to('someonewhocares at yourcompany.com');
$smtp->data();
foreach (@mtr_results) { $smtp->datasend($_) }
$smtp->dataend();

$smtp->quit;
