The HTTP sender publisher sends each point update (or change, as appropriate) to a given destination URL.
The Method selection determines which HTTP method type will be used to deliver the data. The data sent is either case is identical; the difference is a matter of message structure. The URL defines the resource to which to send the data. Valid schemes include "http" and "https". The server can be a domain name or an IP address. Paths and query strings are also valid.
A list of Static headers and Static parameters can also be added. These data are included with every
request sent to the URL. As such, this is an appropriate place to include authorization credentials or other
identifying artifacts. To add a static headers and parameter, enter its key and value, and click the
icon. To delete any existing static header or parameter, click the
icon associated with the entry.
The Date format selection determines how the publisher will format timestamps associated with point values. The "basic" format is of the form "yyyyMMddHHmmss". "Time zone" is similar, but includes more information regarding the locale of the timestamp. It is of the form "yyyy-MM-dd'T'HH:mm:ss'Z'". "UTC" uses a numeric value that represents the number of milliseconds elapsed since midnight on Jan 1, 1970.
Any other response code than a "200 OK" is considered an error, and an alarm will be raised. In addition, any response content included with an OK response is considered to be warning information. The Raise result warning setting controls whether the existence of any response content causes an information alarm to be raised including the content in the event message.
A test request can be sent—using the given configuration but including only static parameters—by clicking the "Send static parameters" button. The result of the send attempt will be displayed below the buttons. To cancel a test before it times out on its own, click the "Cancel" button.
The Points section lists the points to be published. Point publishing can be enabled
() or disabled (
). Disabling a point allows it to
not be used without having to explicitly delete it. The Parameter name is the key that will be used for the
point in the request parameters. The value will be the present value of the point. Select Include timestamp to
include a parameter in the request that contains the update time for the value. The key for the time will be "__time",
and the date will be encoded according to the date format value. (See the "Date/time formats" documentation for
more information.)
To add a point to the point list, select it in the points list and click the
icon. To delete an existing point, click its associated
icon.
