Version 4.1.0 of the File input plugin brings new internals and new features!
In pull request #171, Guy Boertje massively improved the file input code structure, reduced external dependencies and brought in new features, of which we'd like to highlight:
- New 'reading' mode: as opposed to 'tailing', this mode assumes files have ends and are not appended to;
- Support for gzip compressed files (only in reading mode);
- Support expiration of sincedb entries by configuring the `sincedb_clean_after` option
For more information, see the documentation for version 4.1.0.
HTTP Input version 3.1.0: goodbye Puma, hello Netty!
A large rewrite of this plugin's internals (#73) has brought more control over TLS/SSL settings, better handling of backpressure by limiting the number of inflight events over all connections and a modest 10% performance increase and lower memory usage. By building the HTTP layer on top of the Netty Java library this rewrite enables further improvements, as demonstrated in this currently open pull request that brings an extra 15 to 20% gain in performance.
Beta stage implementation of SNMP input is complete!
After a lot of demand for SNMP polling, this initial pull request by Colin Surprenant creates a snmp input plugin that can perform get/walk operations on multiple hosts and use mib files to translate OID to field names. Currently it only supports SNMPv2c over UDP but more is planned, see the plugin's roadmap for more information.
New filter: logstash-filter-bytes
Our own Shaunak has contributed a very useful filter that converts human descriptions of storage size to the canonical number of bytes they represent (e.g. "10 KB" is translated to 10240). See the documentation for more examples and uses.
