| 21 | Implementation of the metrics package that writes the metrics to a file. |
---|
| 22 | Programmers should not normally need to use this package directly. Instead |
---|
| 23 | they should use org.hadoop.metrics. |
---|
| 24 | |
---|
| 25 | <p/> |
---|
| 26 | These are the implementation specific factory attributes |
---|
| 27 | (See ContextFactory.getFactory()): |
---|
| 28 | |
---|
| 29 | <dl> |
---|
| 30 | <dt><i>contextName</i>.fileName</dt> |
---|
| 31 | <dd>The path of the file to which metrics in context <i>contextName</i> |
---|
| 32 | are to be appended. If this attribute is not specified, the metrics |
---|
| 33 | are written to standard output by default.</dd> |
---|
| 34 | |
---|
| 35 | <dt><i>contextName</i>.period</dt> |
---|
| 36 | <dd>The period in seconds on which the metric data is written to the |
---|
| 37 | file.</dd> |
