Diagnosis
You are creating your own monitor definition. The system displays astatic inventory of the systems that can be included in your monitor. Itdoes not make sense to delete these nodes, they are for presentationonly. You can only delete virtual nodes and rule nodes.

Procedure
From the list of selectable MTEs, choose the monitoring objects andattributes that you want to include in your monitor. These MTEs arestatic, that is, your monitor will not be automatically updated with anynew MTEs that are entered in this inventory.
If you no longer want to create a monitor, return to the initial screenof the alert monitor without saving your monitor definition.
