Configuring relationship processing

Use this procedure to configure Resource Manager and Service Impact to use lazy or eager relationship processing.

• Lazy mode is the default setting for release 5.5.x, and it is the appropriate choice when all of the ZenPacks that you use to monitor devices have been updated for optimal relationship processing.

• Eager mode ensures high-accuracy models at the potentially unacceptable cost of low remodeling performance. In large or complex environments, long remodeling times can generate inaccuracies in the model as changes to the underlying devices are processed. Eager mode is appropriate for customers with smaller and less complex models and a low rate of model changes.

Perform these steps:

1. Log in to the Control Center browser interface.

2. Navigate to the Applications > Zenoss.resmgr page.

   

3. On the application title line, click Edit Variables.

   

4. In the Edit Variables dialog box, add the following variable:

   global.conf.corroborating-relationship-provider True
   

   • To configure lazy relationship processing, set the value to True.

   • To configure eager relationship processing, set the value to False.

     If you switch the processing mode from lazy to eager (change the value from True to False), you must rebuild the graph.

5. At the bottom of the Edit Variables dialog box, click Save.

6. On the application title line, click Restart.
