Modifying threshold values for the Server Health Monitor

The Index Thresholds view in the Health Monitoring database (DOMMON.NSF) displays the threshold values for each platform. To modify the sensitivity to a particular component, change the threshold value. For example, if you want to run your networks with higher utilization for servers running on a specific platform, increase the threshold for the Network Utilization component for the platform.

About this task

Keep these considerations in mind if you decide to modify threshold values. First, have a strategy in mind before you change the them. Your strategy should address your system performance needs and reflect your philosophy toward managing servers. Second, if you change threshold values remember that you have done so. Changing any system configuration parameters or adjusting user workload behavior might also have a future impact on these settings. And finally, remember that changing threshold values inappropriately may result in health values that do not accurately reflect server capacity and availability. If you get results that seem inaccurate, restore the default threshold values.


  1. From the Domino® Administrator, click the Server > Monitoring tab.
  2. From the menu, choose Monitoring > Switch to Health Reports.
  3. In theConfiguration folder, click Index Thresholds.
  4. Click the name of the operating system and component for which you want to set the threshold, and then click Edit Threshold Document.
  5. Specify values for the Warning Threshold and Critical Threshold.
  6. Click OK.

What to do next

If you later decide to restore the default threshold values for a component, open the Threshold Document as described in the preceding steps and then click Restore Defaults.
