Kevin,

You're right, OpenLDAP doesn't communicate over SNMP (to my knowledge
anyway). But what you can do is in your snmpd.conf file is assign a
command line to an snmp oid (dont know the exact terminology i think
thats close).

Check out this page for more detailed howto
http://www.int-evry.fr/mci/user/procacci/Doc/monitor-snmp-ldap-rrd-en.html

Basically i just adapted this config to fit our environment, although
the monitor-jp.pl script talked about in here needed to be modified
slightly for OpenLDAP 2.2 and our setup.


check out http://www.int-evry.fr/mci/user/procacci/Files/monitor-jp-2.2.X.pl for monitoring openldap 2.2.X databases .
it is described in chapter 4.3 of the above doc .

MRTG sample from our setup is below:
Target[ldapOperations]:
.1.3.6.1.4.1.2021.8.1.101.41&.1.3.6.1.4.1.2021.8.1.101.47:public@localhost
Options[ldapOperations]: growright, nopercent, noinfo
Title[ldapOperations]: LDAP Operations - Total vs Search
PageTop[ldapOperations]: <H1>LDAP Operations - Total vs Search</H1>
MaxBytes[ldapOperations]: 1000000
YLegend[ldapOperations]: # ops
ShortLegend[ldapOperations]: ops
LegendI[ldapOperations]: Total &nbsp;
LegendO[ldapOperations]: Search
Legend1[ldapOperations]: Total &nbsp;
Legend2[ldapOperations]: Search

Hi James,
I am familiar with MRTG and currently use it to monitor various servers such
as printers and servers.  How do you configure the mrtg to be able to
communicate with the openldap server since the mrtg uses snmp?  I wasn't
under the impression that openldap communicates over snmp.  If you have any
sample mrtg files, it would be greatly appreciated.

Thanks,

Kevin

Hi,

We are using OpenLDAP 2.2.13 and successfully monitor the backend with
MRTG graphs.  There is much more you can do, we just havn't gotten
around to it.  If you need pointers.  Let me know!

Cheers,

James

Hello Everyone,



I am trying to find a good utility to generate statistics for a openldap
server. I have been doing some reading and found there is a built-in
monitor in openldap, however I have not been able to successfully search


it.


Is there configuration that needs to take place for the monitor or does


it


happen automatically?  In addition, how do I query it to generate stats?

If anyone is using another utility that gives them excellent results,


please


include that as well
