Highlights

  • mongodb(): add workers() support (multi-threaded connection pooling)

    The MongoDB driver now supports the workers() option, which specifies the number of parallel workers to be used. Workers are based on the connection pooling feature of the MongoDB C library.

    This increases the throughput of the MongoDB destination driver.

    Example:

    destination {
  mongodb(
    uri("mongodb://hostA,hostB/syslog?replicaSet=my_rs&wtimeoutMS=10000&socketTimeoutMS=10000&connectTimeoutMS=10000&serverSelectionTimeoutMS=5000")
    collection("messages")
    workers(8)
  );
};

    (#3621)

  • mongodb(): template support for the collection() option

    The collection() option of the MongoDB destination driver now accepts templates, for example:

    destination {
  mongodb(
    uri("mongodb://host/syslog")
    collection("${HOST}_messages")
  );
};

    (#3621)

Features

  • time-reopen: Support the time-reopen() option on the driver level for the following drivers:
    • sources: example-diskq-source, python-fetcher
    • destinations: amqp, example-destination, file, http, mongodb, network, pipe, program, pseudofile, python, redis, riemann, smtp, sql, stomp, syslog, tcp, tcp6, udp, udp6, unix-dgram, unix-stream, usertty (#3585)
  • csv-parser(): add drop-invalid() option along with the already existing flag with the same name. This is to improve the consistency of the configuration language. (#3547)
  • usertty() destination: Support changing the terminal disable timeout with the time-reopen() option. Default timeout change to 60 from 600. If you wish to use the old 600 timeout, add time-reopen(600) to your config in the usertty() driver. (#3585)
  • syslog-parser(): add a new drop-invalid() option that allows the use of syslog-parser() in if statements. Normally a syslog-parser() injects an error message instead of failing. (#3565)

Bugfixes

  • date-parser: if the timestamp pattern did not covered a field (for example seconds) that field had undefined value

    The missing fields are initialized according to the following rules:

    1. missing all fields -> use current date
    2. only miss year -> guess year based on current year and month (current year, last year or next year)
    3. the rest of the cases don't make much sense, so zero initialization of the missing field makes sense. And the year is initialized to the current one. (#3615)

  • Fix compilation issues on OpenBSD

    syslog-ng can now be compiled on OpenBSD. (#3661)

  • loggen: debug message printed wrong plugin name (ssl-plugin instead of socket_plugin) (#3624)

  • tls: fixup EOF detection issue in tls (before 3.0 version)

    syslog-ng error message: "I/O error occurred while reading; fd='13', error='Success (0)'" (#3618)

  • kafka: the config() block couldn't contain option that is already a keyword in syslog-ng (example: retries) (#3658)

  • templates: fixed error reporting when invalid templates were specified

    The amqp(), file() destination, sql(), stomp(), pdbtool, and graphite() plugins had template options that did not report errors at startup when invalid values were specified. (#3660)

Packaging

  • bison: minimum version of bison is bumped to 3.7.6 (#3547)
  • java-modules: the minimum version of gradle changed from 2.2 to 3.4 (#3645)
  • light: add to the release tarball (#3613)
