/**
 * @file monitoring.C
 * @brief Sample macro for the a monitoring component;
 *
 * Usage:
 * <pre>
 *   aliroot -b -q monitoring.C | tee monitoring.log
 * </pre>
 *
 * This macro illustrates the creation of an HLT monitoring component.
 * The \b Sample-MonitoringComponent component ignores all input data
 * and just fakes some histograms. The histograms can be sent out via
 * different ways. A real component has to have input data and a parent
 * component providing the data in the chain.
 *
 * The ROOTFileWriter component (AliHLTRootFileWriterComponent) provides
 * a simple means to write ROOT objects to a ROOT file.
 *
 * See AliHLTSampleMonitoringComponent for detailed description.
