UDP Multithreaded Source

The UDP Multithreaded Source origin reads messages from one or more UDP ports. The origin can create multiple worker threads to enable parallel processing in a multithreaded . For information about supported versions, see Supported Systems and VersionsSupported Systems and Versions in the Data Collector documentation.

UDP Multithreaded Source generates a record for every message. UDP Multithreaded Source can process collectd messages, NetFlow 5 and NetFlow 9 messages, and the following types of syslog messages:
  • RFC 5424
  • RFC 3164
  • Non-standard common messages, such as RFC 3339 dates with no version digit

When processing NetFlow messages, the stage generates different records based on the NetFlow version. When processing NetFlow 9, the records are generated based on the NetFlow 9 configuration properties. For more information, see NetFlow Data Processing.

The origin can also read binary or character-based raw data.

When you configure UDP Multithreaded Source, you specify the ports to use and the batch size and wait time. You specify the number of worker threads to use in multithreaded processing and you can specify the packet queue size. When epoll is available on the Data Collector machine, you can also specify the number of receiver threads to use to increase the throughput of packets to the .

You specify the data format for the data, then configure any related properties.

When a stops, the origin notes where it stops reading. When the starts again, the origin continues processing from where it stopped by default. You can reset the originreset the originreset the origin to process all requested data.
