[Fedora-directory-users] How can you monitor replication?

[Ian Meyer]

Hello,

We have a decent sized env. (1 master, 16 slaves in different
datacenters across the world) and we're trying to find a way to
effectively monitor the status of replication. When was the last
update? How many changes were made? How long did it take from start to
finish? I know you can get most of this information from the gui, but
we need to tie it in to our monitoring application. Is this
information stored in a db anywhere? In ldap itself? Any insight would
be appreciated.

Thanks in advance!

I use a script like this:

#! /bin/bash
# Script para verificar el estado de la replicacion del directorio

MAILTO=[e-mail]
STATUSFILE=/var/log/DSLastUpdateStatus.log

ldapsearch -x -D "uid=replmon,ou=Special
Users,dc=sis,dc=personal,dc=net,dc=py" \
  -b 'cn=replica,cn="dc=sis,dc=personal,dc=net,dc=py",cn=mapping
tree,cn=config' \
  -w <password> objectClass=nsDS5ReplicationAgreement \
  nsds5replicaLastUpdateStatus nsds5replicaLastUpdateStart | grep -E \
  "^nsds5replicaLastUpdateStatus|^nsds5replicaLastUpdateStart" >
$STATUSFILE 2>&1

STATUS=`grep "^nsds5replicaLastUpdateStatus" $STATUSFILE |awk '{ print $2
}'`
DETAIL=`grep "^nsds5replicaLastUpdateStatus" $STATUSFILE | awk '{ for (i=3;
i<=NF; i++) printf "%s ", $i }'`
if [ $STATUS -ne 0 ]
then
 echo "ALERT!! Directory replication failed with status: $DETAIL" | mail \
  -s "Directory replication failed" $MAILTO
fi

All this code is EXACTLY what I was looking for. I took this code and
built it to work with nagios. It works great.

#!/usr/bin/perl
use strict;
# Edward Capriolo 2007
# Based on code by # Ivan Ferreira - Enero 2007
#usage perl check_ldap_replication ldapsomething.something.com
"cn=Directory Manager" "mypassword"
"cn=replica,cn=o=something.com,cn=mapping tree,cn=config"

#define command {
#        command_name    check_ldap_replication
#        command_line    $USER1$/check_ldap_replication $HOSTADDRESS$
"$ARG1$" "$ARG2$" "$ARG3$"
#}

my $host=$ARGV[0]; #ldapsomething.something.com
my $cn=$ARGV[1]; #cn=Directory Manager
my $pass=$ARGV[2]; #mypassword
my $base=$ARGV[3]; "cn=replica,cn=o=something.com,cn=mapping tree,cn=config"

my $r_cmd="/usr/bin/ldapsearch -h $host -x -D "$cn" -b "$base" -w
$pass objectClass=nsDS5ReplicationAgreement
nsds5replicaLastUpdateStatus nsds5replicaLastUpdateStart";
#print "$r_cmd\n";
my @list = split ( /\n/, `$r_cmd` );

my $res=-1;
my $line="";

for (my $j=0;$j<@list;$j++){
#       print "$list[$j]\n";
        if ($list[$j] =~ /^nsds5replicaLastUpdateStatus/){
#               print $list[$j];
                $line=$list[$j];
                my @tok = split ( /\s/, $list[$j] );
                $res=$tok[1];
        }
}

if ($res == 0 ){
        print ("Replication OK: $line\n");
        exit 0;
}

if ($res != 0 ) {
        print ("Replication FAILED: $line\n");
        exit 2;
}
