| | | Configuring Event Filters |
Filters are used to filter in or out different events based upon some fields in the event types. By default all events that have had their "Show in Event Viewer?" option ticked are shown which is set in the Event Types table. They are also used for Tools to determine which tools are visible in the expanded view.
Unlike SLAs, Filters do not use RPN logic but are written in a standard fashion. To access the filters, select the Administration menu item Triggers & Filters => Event Filters. You will get the table of currently defined filters.
Filters are only a container that has a Description and is used to hold Filter Conditions. The Description column is what appears in the Event Viewer. To see the the Filter Conditions, click on the View button for the required Filter.
As previously mentioned, a Filter is made up of one or more Filter Conditions. The filter conditions can be joined together with AND or OR operators and the conditions can be based upon different attributes of an event. Table * describes what each column in the Filter Conditions table does.
|
Field | Description |
| Position | Each condition within a filter is ordered. The conditions are evaluated from the lowest position value to the highest. |
| Field | The field that will be evaluated in the event against the value column. |
| Operator | How the Field and Value columns are compared. The operators are: equal; not equal; less than; more than. |
| Value | The value that is compared to the Field, using the Operator. |
To join multiple rows, use the AND and OR rows. These rows have the relevant Field set to AND and OR.
So to make a filter that will show all events of type Configuration or Logins you would make a table like
|
Position | Field | Operator | Value |
| 1 | Event Type | = | Configuration |
| 2 | OR | ||
| 3 | Event Type | = | Logins |
The Filter Fields table is used to create new Fields you can compare things to in the Filter Conditions Table. For most uses of JFFNMS, this table is left alone as it depends on the internal structure of the databases.
