Tools - Observation Factory

Menu options: Observation Factory

This option opens the LEX Observation Factory. This is a place where you can monitor replicated objects and their attribute values on different servers in realtime. The Observation Factory gives you a single view where data changes and replication processes can easily monitored:

  • One object can be monitored on several LDAP servers
  • Several objects can be monitored on any LDAP server
  • You can choose if you want to monitor only certain attributes or all attributes of the object.

The observation factory is also accessible in the dropdown menu of entries in the attribute list panel, the regarding option in the context menus is called Use in ObservationFactory.. .Or you just press the CTRL-B key, no matter if you are in the treeview, object list panel or attribute list panel. If you activate the Observation Factory when you are in the treeview or object list, the observation is activated for the entire object with all its attributes. If you activate the Observation Factory in the attribute list, then only the currently marked attributes will be monitored.

Before the Observation can be started, you will be asked on which additional servers you want to monitor the choosen object / attributes. Basically, the monitoring will start at the server which was used in the current LDAP connection - but you could add some more servers for the monitoring process. In AD environments, LEX tries to show you all the AD domain controllers which could be replication partners for the monitoring, so that you just have to choose them from the list in "Choose one or several domain controllers as additional servers:"

The Observation Factory server selector dialog

The Observation Factory is shown with the selected servers in the following window:
