Name | Type | Unit | Description |
numBytesOut | Counter | Bytes | The total number of output bytes since the source started |
numBytesOutPerSec | Meter | Bytes/Sec | The output bytes per second |
numRecordsOut | Counter | Records | The total number of output records since the source started |
numRecordsOutPerSec | Meter | Records/Sec | The output records per second |
| numRecordsOutErrors | Counter | Record | The total number of records failed to send |
recordSize | Histogram | Bytes | The size of a record |
sendTime | Histogram | ms | The time it takes to send a record |
Note:
- A connector implementation does not have report all the following metrics. But the connectors that do report these metrics should conform to this convention.
- The histogram metrics are usually very expensive, so it is strongly recommended that the connectors do not report them by default. But give the options to the users to enable them on demand.
Scope
The metric group for each source and sink would be the same as ordinary operator scope, i.e. default to <host>.taskmanager.<tm_id>.<job_name>.<operator_name>.<subtask_index>
