Adding an Until modifier

Add an Until modifier to control when a true situation closes: after a period of time or when another situation is true or, if you select both, whichever occurs first.

Before you begin

When the Until modifier is for a sampled situation, the event is closed and will not reopen until the monitored condition turns false and turns true again. However, using a persistent count of 2 or more causes the event to close. But if the condition remains true for the number of intervals equal to the persistent count, the event will reopen for the same condition for which it originally fired. (See step 4 in the procedure for defining the condition to read about persistence and how to set it.)

About this task

This procedure assumes that you are creating or editing a situation in the Situation editor (see Opening the Situation editor. Take these steps to add an Until modifier to the situation.

1. Click the Until tab.

   If it is not open already, open the Situation editor and select the situation to which you want to specify the Until modifier.

2. Specify when you want the situation to close:
   • Check Another Situation is TRUE to close the event when the situation is true and select a situation from the list.

     The situations available are for the same type of monitoring agent that this situation uses or that use the Cloud Pak System Monitoring Server common attributes.

   • Check Reset Interval Expires to close the event after the specified interval, 15 minutes by default.

     To change the interval, click inside dd (day), hh (hour), mm (minute) or ss (second) and click the arrows to adjust up or down, or type the number.

   See Until for more information on choosing an option.
3. Select other tabs in the Situation editor to:
   • Distribute the situation to the managed systems on which you want it to run. See Distributing the situation.
   • Add expert advice to the situation. See Writing expert advice.
   • Specify an action to take or a message to send to the Universal Message Console when the situation is true. See Specifying an action
   • Forward events that open for this situation to an Event Integration Facility receiver such as the Netcool/OMNIbus Probe for Tivoli EIF. See Forwarding the event to an EIF receiver.
4. When you are finished composing the situation, save your changes and start the situation by clicking Apply to keep the editor open; or by clicking OK to close the Situation editor.

   The Situation editor performs syntax checking on each expression you enter. If you entered an improper value for an attribute, such as “abc” for Disk Size, the cell turns red and the situation will not be saved until you correct the error.

   If you opened the Situation editor from the toolbar, the situation you just created will not be associated with any Navigator items and no event indicator is displayed when the situation becomes true. You must associate a situation with a Navigator item or change its state and click Apply.

   Situations are stored at the hub monitoring server. In the unlikely event that two users attempt to save a situation with the same name simultaneously, an error will occur, ensuring that one situation does not overwrite another.

5. If the Distribution Change window is displayed, click OK to add the managed systems shown in the Required Managed Systems list to the distribution for this situation.
