== Event storm properties ==
A storm rule is opened by clicking on its name on the [https://ap1.veloopti.com.au/storm-rules Storm rules] web page which is found under the Events main menu item of Events. These pages are protected using permissions meaning not everyone is able to see them.
When a change is made that does not abide by the logic of the storm rules engine then the text is marked in red indicating that it needs to be changed.
=== Overview ===
The overview tab contains the properties of the storm rule that are common to every severity setting.
:'''Name''': The name of the storm rule. This is used in the short description of the event that will appear in the event view and also in the email subject line.
:'''Description''': This is used to describe the storm rule to other people who are editing it.
:'''Enabled''': This enables or disables the storm rule. A disabled storm rule will not detect or notify of any threshold breaches. It also will not collect any metrics for displaying in a dashboard.

:'''Breach Count''': This is the minimum number of events or duplicates per '''''breach duration''''' that must be exceeded in order to create a storm event with the status of information. As long as a storm event is open and this condition is met, the storm rule will continue to be in breach with an information severity level. When this condition is not being met then the reset conditions are checked to see whether the open event can be closed.
