We have just started using Service Fabric and the only pain point so far has been ETW with WAD, which always seems to log out with missing data (message, eventmessage.)
Our experience so far has that it always works in visual studio (sometimes you have to add the provider name) and that it rarely works when deployed to a cluster in Azure. When it does work in Azure - versioning & updating a function on the event source or adding another will then log out with empty data points.
This is the section we have in our ARM script for ETW/WAD which we are deploying using the Azure CLI.

}
}
]
}
}
},

},

}
This is our EventSource, though we have tried a ton of variations.
using Microsoft.Diagnostics.Tracing;
namespace Project.API
[EventSource(Name = "Company-Project-API")]
public sealed class ApiEventSource : EventSource
{
public static ApiEventSource Current = new ApiEventSource();
[Event(1, Level = EventLevel.Informational, Message = "{0}", Version = 1)]
public void Log(string message)
{
this.WriteEvent(1, message);
}
}
This is what we get in WAD every time.
Running .NET 4.5.2 / .net core.
Please assist.
EDIT - Okay, we've had some success moving up to .NET 4.6 - it looks as if the message payload is being logged out. All we're missing now is the eventmessage field. It also seems that the "message" field is always null now in VS.
EDIT2 - It seems that the message field is missing when using EventSourceSettings.EtwSelfDescribingEventFormat as a constructor argument to your event source like below. This seems to be the case in VS & in WAD.
public sealed class ApiEventSource : EventSource
{
public ApiEventSource() : base(EventSourceSettings.EtwSelfDescribingEventFormat) {}
}
At the moment I can either choose between no eventmessage (Self Describing) or not being able to version the methods (even with incrementing the attribute, empty lines are still dumped into WAD when using manifest style.
