Look - The LDAP operational ORCA "k"ollector
What is Look?
Look is a utility written in Perl which gathers LDAP performance data
at periodic intervals and generates a file of summary results in a format
compatible with the open source ORCA web graphing product (available at http://www.orcaware.com).
Look is capable of retrieving information by parsing LDAP server logs in
either iPlanet Directory Server 4.x format or Sun Java System Directory Server
5.2 default format, as well as querying the LDAP directory directly to retrieve
Version 1.10 includes contributed code from the University of Oregon which
allows parsing of log files in the Sun Java System Directory Server 5.2 default
NOTE: Direct LDAP server querying requires the installation of either PerLDAP
or Net::LDAP. Net::LDAP is recommended.
Development of this software was supported with funding from the University
of Notre Dame, Internet2, and the NSF Middleware Initiative (Cooperative Agreement
Why should I use Look?
If you run an LDAP server and need to answer basic performance questions,
then Look may be just what you need. Couple Look with Orca and
you can collect all kinds of LDAP performance statistics real-time and generate
web graphs that show how your service is performing.
How much does Look cost?
Developed with funding from the NSF Middleware Initiative, Look is
freely available for all institutions of higher learning. All others should
contact the Look author at bbellina
The latest version is Look v1.1:
Where can I see Look in action?
Look is used at the University of Notre Dame to monitor the campus
enterprise directory service. An example graph produced by Orca using data
collected by Look is shown below. To see current performance graphs
