Мониторинг сети

[Антоха Р.]

Доброго времени суток. Подскажите нормальную прогу для снятие трапов со свичей D-Link DGS-3420-26SС?

Можно стандартный net-snmp.

Мне же хватает этого:

#!/usr/bin/perl -w

use strict;
use threads;
use Net::SNMPTrapd;

use constant THREADS_COUNT => 4;
use constant DEBUG         => 0;

my $server_ip = "X.X.X.X";
my $log_filename = "/var/log/snmptraps.log";

open(STDIN,  "+>/dev/null") or die "Can't open STDIN: $!\n";
open(STDOUT, "+>/dev/null") or die "Can't open STDOUT: $!\n";
open(STDERR, "+>>$log_filename") or die "Can't open STDERR: $!\n";

my $obj = Net::SNMPTrapd->new(Family=>'ipv4', LocalAddr=>$server_ip, LocalPort=>162, timeout=>3) or die "Error: ", Net::SNMPTrapd->error;

for my $i (1..(THREADS_COUNT - 1)) { threads->create(\&request_loop, $obj); }
request_loop($obj);

sub request_loop {
 my $snmptrapd = shift;
 my $tid = threads->tid(); # thread ID
 logg($tid, 'START');
 my ($ip, $p, $trap);
 while (1) {
       $trap = $snmptrapd->get_trap();
       unless (defined($trap)) {
               logg($tid, Net::SNMPTrapd->error);
               next;
       }
       next if ($trap == 0);
       unless (defined($trap->process_trap())) { logg($tid, Net::SNMPTrapd->error); }
       else {
               $ip = $trap->remoteaddr;
               $p = "";
               for my $vals (@{$trap->varbinds}) {
                       for (keys(%{$vals})) {
                               $p .= sprintf "%s: %s; ", $_, $vals->{$_};
                       }
               }
               logg($tid, "[$ip] $p") if (DEBUG == 1);
       }
 }
}

sub logg {
 my ($tid, $msg) = @_;
 my $now =  POSIX::strftime("%d.%m.%Y %H:%M:%S", localtime);
 open hFile, ">>", $log_filename;
 print hFile "$now Thread ($tid): $msg\n";
 close hFile;
}
