Schema - LOG.BASIC - XPLProject


LOG.BASIC Message Specification

  • Class = LOG
  • Type = BASIC

This schema provides the ability for a device to transmit information relating to it's operation.

XPL-CMND Structure

Not applicable.

XPL-TRIG Structure

type=inf | wrn | err
text=<text to be logged>
[code=<event-specific code>]

XPL-STAT Structure

Not applicable.

Schema Specific Notes

This schema should be used when a device wishes to transmit information relating to it's operation. Messages using the log.basic schema can be monitored centrally and optionally logged to a database to provide a complete operational activity log of an entire xPL network.

The type element should be used to broadly specify the type of information, and can be one of the following values: inf - The message is for informational purposes only. wrn - A warning message to indicate possible problems with a device that may require the attention of the user. err - An error has occurred, causing a device to fail or become partially inoperative.

The text element should be used to specify the information that is being logged. Device vendors should take note of the 128-character limit that applies to any value within a name/value pair.

The code element can be used to specify a numeric representation of the event. Vendors are free to define their own event codes that are specific to their devices. A complete listing of all possible event messages (and their associated event codes, if implemented) should be included as part of the documentation that accompanies any xPL-enabled device making use of the log.basic schema.

Devices should not generate excessive log.basic messages, particularly of an informational variety, as this could lead to congestion of the xPL network.
