Can't write to ULS

Question

I have done some minor fixes to a timerjob, which writes to ULS after every step and error, but, for some reason after last deployment, it fails and is most confusing to me - doesn't write to ULS (even though from progress it is clearly seen that it should)

Answer 1

The problem is that the farm was on few machines, so the one on which the project was deployed, wasn't the one on which it worked

Answer 2

Try these lines to write on the Log file:

SPDiagnosticsService.Local.WriteTrace(0, new SPDiagnosticsCategory("Your Category", TraceSeverity.High, EventSeverity.Information), TraceSeverity.High, "My log text");
