## Summary of Use event input information

The Event Input pane in the Event Rule designer is a key feature for ServiceNow customers to reference and utilize event data when configuring event rules.
It provides structured event information that can be dragged into alert fields to customize alert content effectively.
This pane appears in all Event Rule designer sections except the Event Rule Info section, serving mostly as a read-only reference except in the Transform and compose alert output section where it is editable.

## Key Features

* **Event Input Pane Sections:** The pane includes four sections---Event Additional Info, Expressions, Event Raw Info, and the ability to define custom alert tags for specific customization needs.
* **Edit Modes:**
  * **Standard Edit Mode:** Allows marking and transforming text by selecting field names but does not allow text editing or undo.
  * **Regex Edit Mode:** Enables direct text editing in the work area with regular expression syntax for flexible field creation and transformation, though undo is not available. Reset returns the field to its original value.
* **Event Additional Info:** Displays default and custom fields used in alerts; these fields can be dragged into the alert configuration work area.
* **Expressions:** Allows creation of new fields by transforming event raw or additional info data, facilitating more granular customization of alert content.
* **Event Raw Info:** Contains all fields from the Event form and supports creating new expressions by selecting text to define new field values.
* **Field Control:** Customers can manage field visibility using the exclusion list (\[emeventruleblacklist\] table) and order fields using the emeventruleorder form to tailor the Event Input pane's appearance.

## Practical Use for ServiceNow Customers

This functionality empowers customers to customize alerts precisely by using event data fields and expressions. By dragging and transforming event input information, customers can create meaningful alerts that suit their operational needs. The regex edit mode supports advanced text manipulation, enabling complex field definitions.

Managing field visibility and order allows customers to streamline their configuration experience by focusing only on relevant data fields.

## Additional Considerations

* Ensure variables in regex expressions are created and used in sequential order to maintain proper input processing.
* The Event Input pane is read-only in most sections except where alert output is composed and transformed.
* Accessibility settings may limit editing modes available.  
The Event Input pane that is included in the steps to create an event rule provides a reference to the information that you can use when configuring an event rule. {#event-input-information__ph_MIDWebServerShortDesc}

In the Transform and compose alert output pane, you can also drag the
information into the required fields to customize alert content. The fields in the right-hand
pane appear as a reference to which fields, expressions, and their values are available when
working in the Event Rule designer. The fields that display in the Transform and compose alert
output left-hand workarea become the fields in the generated alert form. In addition, you can
define alert tags that are specific for customization.

## General components and navigation

The Event Input pane consists of these sections:

* Event Additional Info
* Expressions
* Event Raw Info
{#event-input-information__ul_x2d_3y3_wy} The Event Input pane displays in all Event Rule designer sections,
except for the Event Rule Info section. The fields in the right-pane
can be modified only in the Transform and compose alert output section.
In all the other sections, the Event Input pane is read-only and
available for reference purposes.  
Note:  
If Accessibility enabled ![Accessibility enabled]() is selected in System Settings, standard edit mode is not available ![Standard edit mode icon]().

## Edit modes

{#event-input-information__table_d5z_gym_xy__entry__2}

| Mode | Description |
|-|-|
| Standard edit mode ![Event Management icon]() | Text selected in the left-hand workarea cannot be edited. Undo is not available. In this mode, you can only mark the text or values and transform it by selecting a field name. |
| Regex edit mode![Event Management icon]() | Edit text in the left-hand workarea by selecting it, as required. After you have edited the text, you cannot go back to the standard mode. Undo is not available. However, Reset is available, returning the field to its original value. You can compose text using regular expression (regex) format conventions, for example, type (.\*) to create a field name. You cannot use field values like: type "$" to include the value of a field and specify the name of the field in parentheses {}. You can include special characters in a field by "escaping" them, that is, by prefixing the character with a "\\". For example, to include a "\\" in your text, enter "\\\\". |

## Event additional info

The Event additional info section displays
default event form fields, plus fields that were created to display in alerts and that are
added to the Additional information section of the alert.
When configuring text in the fields in the left-hand workarea, you can drag field names and/or their value from this section into the fields.

## Expressions

The Expressions section is available only if an additional information field was created.
You can create expressions from event raw data or from additional information data.

1. Click in a field in the Event Input pane to perform transformation actions.
2. Create an expression by transforming information and associating it with a field name. Either select a field name from the suggested list, or create a field name, as required.

3. Click in a field in the Event Input pane. In the left-hand workarea, select the required information.

{#event-input-information__ol_yt3_j3h_1z}

Create expressions by transforming information and associating it with a field name. Select
a field name from the suggested list, or you can create a field name, as required.

## Event raw info

The Event raw info section is always available. Its
contents are the fields from the Event form.
To transform text, click a field in the right-panel to open it in the work area on the left-panel, in the Mark Expressions section. You can select text in the Mark Expressions section where the selected text becomes the value of a newly created field. Name the new field. This new field is added to the Expressions section.  
Note:  
When creating regex expression for input, ensure that you create input with the variables in sequential order. While variables can be skipped for inclusion, the selected order must be maintained.  
Controlling how fields appear:

* Use the exclusion list \[em_event_rule_black_list\] table to hide fields from the right-pane.
* Use the em_event_rule_order form to order the position of each field.
* Fields that are not in the exclusion list and also not part of the em_event_rule_order table, still appear in the event rule designer, in the right-panel and in the Transform and Compose Alert Output tab.

* [Create or edit an event rule](https://servicenow-prod.fluidtopics.net/S0ulPjfvh7Pz7phgkfVYFw "You can create event rules to generate alerts for tracking and remediation. Use team-based integrations in event rules to make sure that connector ownership and execution of rules give precedence to general rules. Teams can maintain consistency and hierarchy while offering flexibility and customization options.")
* [Configure an event rule to customize alert content](https://servicenow-prod.fluidtopics.net/y3wetDYMwXph7QgT~DFEhg "You can configure an event rule to customize alert content. You can customize the order of the fields and select which fields display. The fields in the left-hand work area of the Transform and Compose Alert Output section of an event rule are the fields that appear in the generated alert.")
* [Filter the events that an event rule applies to](https://servicenow-prod.fluidtopics.net/ieu8q5TI7rJv10SQ5gdxgw "Define a filter to restrict to which events the event rule must apply. Configure the filter by providing a set of conditions that each event must match to be either excluded or included from applying to the event rule.")
* [Set a threshold to suppress alert generation](https://servicenow-prod.fluidtopics.net/hz5gPG5ZhuIhZeKZaBd7gA "The event threshold is the rate upon which Event Management generates an alert. Receiving multiple events for a device over a short interval may warrant creating an alert, as the condition may be serious. However, receiving events over a longer interval may indicate a less serious situation which would not warrant creating an alert.")
