Monitor Active Directory Replication

[Collier, Tirus]

Here's a script to check synchronization between DCs, more perl scripts are available at
http:/rallenhome.com
 
# This Perl code prints the up-to-dateness vector for the DCs defined in
# the  arrDCList for the naming context defined by $strNCDN

# ---------------------------------------------------------------
# Adapted from VBScript code contained in the book:
#      "Active Directory Cookbook" by Robbie Allen
# Publisher: O'Reilly and Associates
# ISBN: 0-596-00466-4
# Book web site: http://rallenhome.com/books/adcookbook/code.html
# ---------------------------------------------------------------

# ------ SCRIPT CONFIGURATION ------
# Set to the DN of the naming context you want to check the DCs against
my $strNCDN = "<NamingContextDN>";
# Enter 2 or more DCs to compare
my @arrDCList = ("<DC1Name>","<DC2Name>");
# ------ END CONFIGURATION ---------
use Win32::OLE 'in';
$Win32::OLE::Warn = 3;
my $objIadsTools = Win32::OLE->CreateObject("IADsTools.DCFunctions");

foreach my $strDC (@arrDCList) {
   print "Replication partner USNs for $strDC:\n";
   $intUSN = $objIadsTools->GetHighestCommittedUSN( $strDC,0);
   if ($intUSN == -1) {
      print "Error retrieving USN: ", $objIadsTools->LastErrorText,"\n";
      exit;
   }
   print "\t$strDC = $intUSN\n";

   my $intRes = $objIadsTools->GetReplicationUSNState( $strDC, $strNCDN,0,0);
   if ($intRes == -1) {
      print "Error retrieving USNs: ", $objIadsTools->LastErrorText,"\n";
      exit;
   }
   foreach my $count (1 .. $intRes) {
      print "\t", $objIadsTools->ReplPartnerName($count),
                " = ", $objIadsTools->ReplPartnerUSN($count),"\n";
   }
   print "\n";
}

get nagios eventlog agent here :
http://www.steveshipway.org/software/f_nagios.html

figure out the event source and eventID for the directory replication
success / failure , create a filter for nagios eventlog, create a new nagios
check-command and you're done.
Do read the manuals, though... (specially the nsca stuff)
