Description of the event. This text can be re-read from the event observer by displaying the details of the event.

Type of event that will be written into the Windows log:

elError	Error event. Signals an error while running a service. Services do not have the mean to display information: therefore, this is the main method for reporting an error.
elInformation (default value)	Information event. Indicates the status of service. For example: change of activity mode, startup, ...
elWarning	Warning event. Indicates that a non fatal error occurred while running the service. For example: an operation was successfully performed but no notification message was sent.

Event identifier (found between 1 and 100).
Tip: Use a different value for each event of the service in order to easily differentiate among them.
This value can be retrieved by the applications that read the event log in order to trigger actions.
