Store the lines in a hash of arrays (HoA) (see perldsc) and print them after all the lines have been scanned/counted

while ( my $line = <DATA> ) {
  next if $line =~ /Insufficent|CLEARED/;
  if ( $line =~ /SNMP/ ) {
    my @f = split /\|/, $line; 
    my $node_ip = $f[4] || 'N/A';
    my $message = $f[13];
    my (undef,$ne) = split /[ &]+/,$f[15];
    
     if ( $seen{$ne} ){
       ++$seen{$ne}[0];
     } else {
       $seen{$ne} = [ 1, $node_ip, $ne, $message ];
    }
  }
}

for my $ne ( sort keys %seen ){
  printf "%d | %-15s | %9s | %s \n", @{$seen{$ne}};
}

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
