Hi Ralf, I'd suggest for the option format something like this: -gz[=level]
where level is an int. The part [=level] is optional. The level is 0 by default (if it is not set). Thanks, Serguei On 2/11/20 7:35 AM, Schmelter, Ralf wrote:
Hi Yasumasa, I think I've tried too much by using the -gz flag as a boolean plus a int value. I've decided to use two options instead: -gz as a boolean option to turn compression on and -gz-level to specify the compression level. E.g. GC.heap_dump -gz -gz-level=3 test.hprof.gz Best regards, Ralf
