Question

See more:

We are logging custom events from application to ETW. Now need to find the best compression technique as lots of data will be written to the file and the etl file is to be send with error report to the server.

How to specify the details? In System.Diagnostics.Tracing.EventSource itself, when setting it up?

What I have tried:

Not seeing what is the option/setting to specify compression details. So waiting for some guidance

Why don't you ask the people making that software ?
We are not their support service.

You mean Microsoft? Seems you don't know ETW - have a look https://docs.microsoft.com/en-us/windows/desktop/etw/event-tracing-portal

Depend's how you use it, but Maybe this helps: ETW Trace Compression (and xperf syntax refresher) | Random ASCII[^]

Thanks @johannesnestler. But I am not allowed to use any third party tool. And the purpose is the messages written from our application, creates a new session and when a crash occurs, the reporting tool of ours acts to end current session, which writes the logs from memory to file. Instead of later compressing the file data, (before sending it to customer support), checking if any option to compress before the data goes to the file.

xperf is part of the Windows SDK - so not really 3rd Party. if you have both sides in your Hands you can do the compression/decompression manually - but I think this is what you want to avoid.
