Always make global threshold changes from the TrueSight console for the following reasons:
The changes made at the TrueSight console are propagated to all TrueSight Infrastructure Management Server instances in your tenant.
Global threshold changes done at the TrueSight Infrastructure Management Server-level are only applied locally and are not propagated to other Infrastructure Management servers.
Restarting a TrueSight Infrastructure Management Server after making the global threshold changes locally causes global thresholds from the TrueSight Presentation Server to be reapplied to the Infrastructure Management Server local changes done at the TrueSight Infrastructure Management Server before a restart are overridden.
In addition, before configuring the global thresholds settings, ensure that the monitor type exists in the TrueSight Infrastructure Manager. Suppose if it does not exist at the time of configuring global thresholds and you added the monitor type later, then either restart the TrueSight Infrastructure Management Server or edit and save the global threshold settings for the monitor type again from the TrueSight console for the settings to be applied.
Note
BMC recommends that you use the TrueSight console to manage and view these threshold configurations, as described in Managing-global-thresholds-on-the-TrueSight-console. Do not use the operator console to set thresholds.
