Alberto Bustamante Reyes commented on GEODE-8065:
-------------------------------------------------
There is a distributed test case verifying the export to csv (
ShowMetricsDUnitTest.testShowMetricsMemberWithFileOutput() ) and it passes on
develop branch. Anyway I tried the process manually, and the export works fine:
the file is created and it has content inside.
> show metrics --file option not exporting data to csv
