Hello,

I have been reviewing the gateway logs for my project and noticed many of the log entries have a series of characters at the end that seem to be related to the error location. i.e. "@D$0:1"  
Here are some examples of what the log messages look like:

Does anyone know what the syntax is for these messages?

Thank you!

The C or D means 'client' or 'designer'. The sequence of integers after that represent component indices.

Okay thank you, to follow up I was wondering:

What the L represents in my first screenshot?

Given my view has the following structure what component would D$0:1 represent? (is the first index the root container? or does it start a level below that)

It starts from the root container; so it'd be `0` (root container) then `1` (PowerChart) in your screenshot.

I'm actually not really sure what the `L` means... 😅
