Explanation:
-Xverbosegclog[: <file> [,<X>,<Y>]]
Causes -verbose:gc output to be written to the specified file.
If it cannot create the file (for example, if an invalid filename is passed into the command),
it will redirect the output to stderr.
If you specify <X> and <Y> the -verbose:gc output is redirected to <X> files, each
containing <Y> GC cycles.
The dump agent tokens can be used in the filename. See Dump agent tokens for more
information. If you do not specify <file>, verbosegc.%Y%m%d.%H%M%S.%pid.txt is used.
example: -Xverbosegclog:newgclogname.log,7,10000
