23 | * @class AliHLTMonitoringRelay | |
24 | * A relay component for monitoring data objects. | |
25 | * It keeps a copy of the last block of every parent and forwards all | |
26 | * the blocks together. By that, the output of histograms (rarely to | |
27 | * be published but for every event filled. | |
28 | * | |
29 | * Input data blocks must be uniquely identified by the combination of | |
30 | * - data type (id and origin) | |
31 | * - block specification | |
32 | * - object name | |
33 | * - object title | |
34 | * | |
35 | * <h2>General properties:</h2> | |
36 | * | |
37 | * Component ID: \b MonitoringRelay <br> | |
38 | * Library: \b libAliHLTUtil.so <br> | |
39 | * Input Data Types: kAliHLTAnyDataType <br> | |
40 | * Output Data Types: according to input blocks <br> | |
41 | * | |
42 | * <h2>Mandatory arguments:</h2> | |
43 | * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting --> | |
44 | * | |
45 | * <h2>Optional arguments:</h2> | |
46 | * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting --> | |
47 | * \li -verbose <br> | |
48 | * print out some more info messages, mainly for the sake of tutorials | |
49 | * | |
50 | * <h2>Configuration:</h2> | |
51 | * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting --> | |
52 | * Configuration by component arguments. | |
53 | * | |
54 | * <h2>Default CDB entries:</h2> | |
55 | * The component loads no CDB entries. | |
56 | * | |
57 | * <h2>Performance:</h2> | |
58 | * Low profile: input objects are unpacked and binary copied, no streaming | |
59 | * of obejcts. | |
60 | * | |
61 | * <h2>Memory consnumption:</h2> | |
62 | * The component allocates memory of the maximum size for every input | |
63 | * object. | |
64 | * | |
65 | * <h2>Output size:</h2> | |
