Directory Service Operational Issues
  • Transaction Performance Monitoring at the
    University of Notre Dame

Presentation Overview
  • Why Monitor Performance Metrics
  • What Performance Metrics To Monitor
  • How To Monitor Performance Metrics
  • Notre Dame EDS Performance Monitoring

3
Why Monitor Performance Metrics
  • Availability
  • Its up isnt it?
  • Responsiveness
  • Its fast enough maybe.
  • Scalability
  • We can handle that I think.

4
What Performance Metrics To Monitor
Bind response time Search response time Current
connections Avg connection length Current
binds Current searches Peaks
  • Response time
  • Connection requests
  • Bind requests
  • Bind errors
  • Search requests
  • Search errors
  • Avg count size of search results

5
How To Monitor Performance Metrics
  • Directory internal query (iPlanet, OpenLDAP?)
  • base search on cnmonitor
  • base search on cnmonitor,cnldbm
  • Log File Analysis
  • Perl (PerLDAP)

6
How To Monitor Performance Metrics
  • NMS (Network Management System)
  • HP OpenView
  • CA/UniCenter TNG
  • IBM NetView
  • others
  • Operating System Tools
  • Win NT Event Viewer
  • Sun Solaris SE Toolkit

7
Notre Dame EDS Performance Monitoring
  • Directory Probing via HP/OpenView (Jrodent)
  • ORCA
  • Operating System Performance via Orcallator
  • Log File Analysis trending troubleshooting

8
Directory Probing
  • Ping
  • Query to directory service
  • Bind to directory service
  • Automatic alert to operations center
  • Cycle every 5 minutes

9
ORCA (http//www.orcaware.com)
  • About ORCA
  • Generates web friendly performance graphs based
    on collected statistical data.
  • Free (will take donations)
  • Open Source
  • Perl
  • Used by Yahoo!/Geocities
  • Used at Notre Dame on 100 servers
  • Hourly, Daily, Weekly, Monthly, Quarterly,
    Yearly, All
  • Did I say free?

10
ORCA _at_ Notre Dame
  • CRON job runs every 15 minutes to regen graphs
  • Orcallator (SymbEL script included with ORCA)
  • Written to monitor web servers and Solaris
    stats
  • Requires Sun Solaris SE Toolkit (free from
    http//www.setoolkit.com)
  • Runs on each directory server to collect
    statistics 5 minute averages, 30 second peaks
  • Data is consolidated on one server for ORCA
    processing
  • Modifications by ND to read iPlanet Dir Server
    4.16 log

11
ORCA _at_ Notre Dame
  • ND Modifications by Jeremy McCarty
  • LDAP connection rate
  • LDAP Bind rate
  • LDAP Bind error rate
  • LDAP search rate
  • LDAP search error rate
  • LDAP search results returned rate
  • Picture is worth 1000 words

12
ORCA _at_ Notre Dame
  • Planned enhancements
  • Stats for search response, bind response
  • Split LDAP log processing into separate Perl
    script
  • - Portability
  • - Maintainability
  • - Removes requirement for SE Toolkit
