Removing unwanted alarms from Spectrum OneClick

Issue/Introduction

In a scenario for where for example you had created a custom event code and set in the events alarm options "Generate a Unique Alarm for Each Event " you may see over time a number of alarms being generated that are not required if there is no clear event created to also remove these alarms.

When setting the "Generate a Unique Alarm for Each Event" option instead of just seeing the occurrence count increase on the first alarm raised you will have a new separate alarm raised in OneClick every time the event that generates this alarm is created.

Resolution

To remove the unwanted accumulated alarms do the following:

1. If there has been no clear event defined then you can add a temporary one, via Event Configuration (you can also do so if you already have one but want to mark this as special clearing, then just use a temporary event code to do it) to clear the alarms.
   
   
2. As per the "Configure Events to Clear Alarms" section of the documentation: 
   
   
   1. Select the event in the Navigation panel, and then click the Alarms tab in the Details panel.
      
      
   2. Under Cleared Alarm(s), click (Adds an alarm to the list).
      
      The Add Cleared Alarm dialog opens displaying the alarm cause codes for all alarms currently loaded into Event Configuration.
      
      
   3. Click Browse, and in the Select Alarm Cause Code dialog, select the alarm cause code of the alarm to clear.
      
      To help you identify the desired alarm, you can enter a text string in the Filter text box to filter the list to include only the alarms with displayed properties that contain the text string.
      
      
   4. Click OK.
      
      
   5. If the alarm you want to clear was generated based on event variable discriminators, select Clear Options, and then specify how the alarm should be cleared. You can select one of the following options:
      
      All Alarms
      
      Select this option if the event should clear all existing instances of the alarm regardless of whether the values in the alarm-clearing event match the values stored in the alarm instances.
      
      Event Variable Discriminators
      
      Select this option if the event should clear existing instances of the alarm based on the values of the alarm's variables (which are copied from the alarm-generating event to the alarm when the alarm is generated). Then enter a comma-separated list of event variable IDs (for example: 1,3,5). You must enter each ID; ranges of IDs are not supported.
      
      The alarm is cleared by the alarm-clearing event if the values in event match the values stored in the alarm.
      
      For examples of using event discriminators to clear alarms, see Clearing Alarms (see page 124).
      
      
   6. Click OK.
      
      
   7. (Optional) Repeat the preceding steps to add additional alarms to be cleared.
      
      
3. Once you have created the clear event next you just need to send that clearing event to every model
   which has had this alarm generated on it via CLI (you need to have the models handle):
   
   cd $SPECROOT/vnmsh
   ./connect.exe
   ./create event type=< clearing event code> text= mh=< model handle of alarmed device/model >
   
   
4. This will then clear every instance of that alarm on the model. Of course they will start fresh but ongoing it should not be getting new alarms generated anyway.
   
   
5. Ongoing the original event generating the event can be modified to uncheck "Generate a Unique Alarm for Each Event" so that unwanted alarms are not created.
