I think this looks good. I added serviceability-dev to the mailing list.

Good point. I have changed Develop to DevelopInfo. I think it's better to maintain the same levels of levels on the develop side so that the logging can just shift laterally to non-product, as it were.

And yes, they are specified as -Xlog:=developdebug Updated webrev: http://cr.openjdk.java.net/~rprotacio/8142366.01/ I re-tested with logging jtreg tests and ExecuteInternalVMTests test, and for anyone who was curious (namely Max who had the good idea for me to check), the debug levels do correctly "nest" with more verbose ones printing out the less verbose and product mode logging as well.

Hi Rachel, I sort of thought DevelopDebug would replace plain Develop, and DevelopTrace would be additional lower level. Maybe plain Develop should be DevelopInfo then? Another question - how do you specify these levels? Is it -Xlog:itables=developdebug ? Thanks, Coleen On 11/9/15 5:55 PM, Rachel Protacio wrote: Hello,

Please see my small changeset to add two develop levels to UL. Summary: This adds develop (that is, non-product) logging levels to the Unified Logging framework in order to support performance, footprint, and usefulness-of-output considerations while maintaining the ability for the user to specify levels of verbosity, i.e. default, "debug," and "trace" levels. Open webrev: http://cr.openjdk.java.net/~rprotacio/8142366/ Bug: https://bugs.openjdk.java.net/browse/JDK-8142366 I tested the added levels locally with sample log messages to ensure proper functioning. When I convert future tags to logging with these levels, those tags will have their own tests and inherently exercise the added levels. Thank you, Rachel
