Outline

• Why a new monitoring system?
• Goals
• Implementation in MOM 2005
• Conclusions
• QA

3
Why a new monitoring system?

• Old monitoring system
• Dedicated server for web server monitoring
  (WEBALARM01)
• Different rules for each server based on text
  configuration file
• Not everything was monitored (e.g. PHP)
• VB6 code which cannot be easily maintained

4
Goals

• Integrate web server monitoring with existing MOM
  system (rules and scripts running on MOM server)
• Improve monitoring rules
• Record web server response time using performance
  counters
• Remove need for dedicated monitoring server
• More flexibility (must be easy to
  add/change/remove monitoring rules)
• Stable and error-proof system (24/7 working
  system with no impact on MOM server)

5
Implementation in MOM 2005

• Creation of a management pack that consists of
• Scripts written in VBscript, performing the URL
  monitoring
• A Rule Group containing all the rules necessary
  for the monitoring, error handling, notification,
  etc
• A Computer Group containing the computer where
  the rules will run WEBSVC02

Conclusions

• MOM 2005 based web server monitoring system is
  capable of
• Monitoring a set of URLs and reporting their
  status back to MOM 2005
• Providing server performance statistics, through
  the use of performance counters
• In case of alert, notifying web.services or CC
  operators according with the alert severity
• Detecting when the monitoring system itself is
  not working

9
Conclusions

• Improvements in web server monitoring
• Certificates expiration check added
• WebAdminServices monitoring added
• General improvements
• MOM 2005 is a recent Microsoft product. Very poor
  and/or erroneous documentation exists (1 book
  internet) thus the work weve been carrying has
  been a lot of trialerror. Internal documentation
  will help everyone prevent mistakes already made.

10
Conclusions

• Further work
• Write an ASP.NET control to provide users a
  graphical view of the web servers state in a web
  page (much like the windows/mail services status
  page)
• Update MOM 2005 documentation webpage
  https//websvc02.cern.ch/winservices-new/Internals
  /Documentation/MOMConf.aspxWebService
• Import data from web server usage analysis into
  MOM and display it together with web server status
