The Diagnostics Collector supports various options that
can be set in a properties file.
Diagnostics Collector can be configured by using options that are
set in a properties file. By default, the properties file is
jre/lib/dc.properties.
If you do not have access to edit this file, or if you are working
on a shared system, you can specify an alternative filename using:
-Xdiagnosticscollector:settings=<filename>
Using a settings file is optional. By default, Diagnostics Collector
gathers all the main types of Java™ diagnostics
files.
