OID Structure

The OID used to poll the Watson Explorer Engine SNMP agent has the following structure:

  .1.3.6.1.4.1.33459.{install-dir-code}.{status-path}.{extra}

• install-dir-code - This variable depends on the installation directory of your local installation of Watson Explorer Engine. If you have multiple installations of Watson Explorer Engine, the install-dir-code will be different for each installation directory.
• status-path - This variable denotes the type of status for which you want more information. The available types are:
  1. Search Collection status
  2. Dictionary status
  3. Services status (Scheduler, Alerts, Reporting, Source Test, Query Service)
  4. Misc (Repository, Users)
• extra - This string refers to the numerical representation of the search collection or dictionary name and is derived from the length of the name of the collection/dictionary and the ASCII decimal value of each character.

To determine the OID structure for your Watson Explorer Engine installation, you can run the snmp-config application in the repository to generate the OID for you. The snmp-config app can be accessed through a browser by going to a URL of the form http://HOST/vivisimo/cgi-bin/velocity?v.app=snmp-config. The snmp-config app has two function:

• snmp-mib-create - produces a MIB
• snmp-config - produces a configuration that can be used with your network monitoring tool, such as Nagios or MRTG, to monitor Watson Explorer Engine.
