/*
 * Compilation Notes:
 * To build the above code, it needs to be linked with ExtAPIs lib exposed by Resource Tuner,
 * and built as a shared lib:
 * => Create the shared lib:
 *    "g++ -fPIC -shared -o libplugin.so Plugin.cpp -lExtAPIs"
 *    This creates a shared lib, libplugin.so
 * => Copy this lib to "/etc/resource-tuner/Custom", the location where Resource Tuner expects
 *    the custom Extensions lib to be placed.
 * => Make sure the lib file has appropriate permissions:
 *    "sudo chmod o+r /etc/resource-tuner/Custom/libplugin.so"
