Code:
#!/usr/bin/perl -w
while (<STDIN>) {
        if (/^([^\s]*)\s+([^\s]+ -> .*) (\d+)$/) { $first=$1;$second=$2;$third=$3;write }
}

format STDOUT =
@<<<<<<<<<<<< @<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< @##########
$first,$second,$third
.

More info on format
You can tweak the @<<<< bits to get things laid out as you want them.

Does this do what you want? (You may have to adjust the spacing.)

Code:
awk '{ x = $2 " " $3 " " $4; printf "%-10s %-30s %4d\n", $1, x, $5}'
