Project Description

This library is provided to allow standard python logging to output log data as json objects ready to be shipped out to logstash.

Installing

Pip (PyPI):

pip install logstash_formatter

Manual:

python setup.py install

Usage

Json outputs are provided by the LogstashFormatter logging formatter.

import logging
from logstash_formatter import LogstashFormatterV1

logger = logging.getLogger()
handler = logging.StreamHandler()
formatter = LogstashFormatterV1()

handler.setFormatter(formatter)
logger.addHandler(handler)

The LogstashFormatter may take the following named parameters:

  • fmt: Config as a JSON string that supports:
    • extra: provide extra fields always present in logs.
    • source_host: override source host name.
  • json_cls: JSON encoder to forward to json.dump.
  • json_default: Default JSON representation for unknown types, by default coerce everything to a string.

LogstashFormatterV1 adheres to the more 1.2.0 schema and will not update fields, apart from a special handling of msg which will be updated to message when applicable.

You can also add extra fields to your json output by specifying a dict in place of message, or by specifying the named argument extra as a dictionary. When supplying the exc_info named argument with a truthy value, and if an exception is found on the stack, its traceback will be attached to the payload as well.

logger.info({"account": 123, "ip": "172.20.19.18"})
logger.info("classic message for account: {account}", extra={"account": account})

try:
  h = {}
  h['key']
except:
  logger.info("something unexpected happened", exc_info=True)

Sample output for LogstashFormatter

The following keys will be found in the output JSON:

  • @source_host: source hostname for the log
  • @timestamp: ISO 8601 timestamp
  • @message: short message for this log
  • @fields: all extra fields
