Hi,
I used this snippet in an ad hoc data source to generate information events.
public void DebugInfo(string debugInfo)
{
var request = new GenerateAlarmMessage();
request.DataMinerID=-1;
request.ParameterID=-1;
request.ElementID=-1;
request.Comment = "";
request.Severity = AlarmSeverity.Information;
request.Status = AlarmStatus.Cleared;
request.Value = "DEBUG:" + debugInfo;
_dms.SendMessages(request);
}

note: This is an internal call and we do not recommend using this, as it is not officially supported and we cannot guarantee that it will still work in the future. As a rule, you should avoid using SLNet calls, as these are subject to change without notice.
