HeapDumper Pluging
This plugin adds the /heapdump command to your server, it requires the permission heapdump which is given
to OP players by default.
The command takes a memory heap dump and saves it as a file in the server’s directory. The file name uses the
current system time by default, but you can customize it by command argument.
Be aware that the heap dump files are usually very big since it will dump the entire application memory in use in a single
file, this means that if your server is using 4GB of RAM when the command is executed, the file will also take 4GB
in the disk space.
Also be aware that heap dump files may contains sensitive information, like database connection information and
unencrypted passwords, so never leave the dumps there.
