Sends a notification to a specified FME Server. The notification may be used for a variety of actions, such as triggering a downstream workspace, or sending an email message to subscribed clients.
Dependencies
This transformer requires an FME Server connection.
Output Ports
Output
Features are output through this port for every notification that was successfully sent. Each feature will have the following attributes exposed:
- _notifier_topic: Topic to be notified
- _notifier_content: The contents of the notification
<Rejected>
Features are output through this port when a notification fails to be sent. Each feature will have the following attributes exposed:
- _notifier_topic: Topic to be notified
- _notifier_content: The contents of the notification
- _failure_reason: If failed to send a notification, the failure reason
- _http_status_code: If failed to send a notification, the HTTP status code
Failure to successfully send a notification will not halt the translation.
Performance Considerations
Windows systems may experience slow performance in situations where a high volume of notifications are sent. Performance may improve by disabling automatic proxy detection:
- Click the Start menu,
- In the 'Search programs and files' textbox, type 'proxy' and select 'Configure proxy server'.
- In the Internet Properties dialog, Connections tab, click LAN settings.
- Uncheck Automatically detect settings.
- Click OK.
Connection
You can connect to an FME Server in one of the following ways:
Connection
Specify a web connection to an FME Server. Web connections can be reused in multiple workspaces, and connection parameters are hidden in the workspace. For more information, see Using Web Connections.
Embed Connection Parameters
When checked, you must specify the connection parameters to the FME Server manually. The connection parameters are visible in the workspace. To connect, specify:
FME Server URL
Enter a URL to access FME Server. You may need to contact your System Administrator for the URL.
Username and Password
Provide your FME Server credentials.
Note: You can click the Status hyperlink to ensure that the FME Server connection has been successfully established.
Parameters
Topic
This parameter is the notification topic. Different FME Server notification subscriptions respond to different topics, so this topic eventually determines which actions are triggered.
Content
This parameter specifies the notification content.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click 
beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
Defining Values
There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.
How to Set Parameter Values
Using the Text Editor
The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.
Using the Arithmetic Editor
The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.
Conditional Values
Set values depending on one or more test conditions that either pass or fail.
Parameter Condition Definition Dialog
Content
Expressions and strings can include a number of functions, characters, parameters, and more.
When setting values - whether entered directly in a parameter or constructed using one of the editors - strings and expressions containing String, Math, Date/Time or FME Feature Functions will have those functions evaluated. Therefore, the names of these functions (in the form @<function_name>) should not be used as literal string values.
Content Types
| These functions manipulate and format strings. | |
|
Special Characters |
A set of control characters is available in the Text Editor. |
| Math functions are available in both editors. | |
| Date/Time Functions | Date and time functions are available in the Text Editor. |
| These operators are available in the Arithmetic Editor. | |
| These return primarily feature-specific values. | |
| FME and workspace-specific parameters may be used. | |
| Creating and Modifying User Parameters | Create your own editable parameters. |
Dialog Options - Tables
Transformers with table-style parameters have additional tools for populating and manipulating values.
Table Tools
|
Row Reordering
|
Enabled once you have clicked on a row item. Choices include:
|
|
Cut, Copy, and Paste
|
Enabled once you have clicked on a row item. Choices include:
Cut, copy, and paste may be used within a transformer, or between transformers. |
|
Filter
|
Start typing a string, and the matrix will only display rows matching those characters. Searches all columns. This only affects the display of attributes within the transformer - it does not alter which attributes are output. |
|
Import
|
Import populates the table with a set of new attributes read from a dataset. Specific application varies between transformers. |
|
Reset/Refresh
|
Generally resets the table to its initial state, and may provide additional options to remove invalid entries. Behavior varies between transformers. |
Note: Not all tools are available in all transformers.
