A tail for JSON logs.

Project Description

A tail for JSON logs.


  • TODO


0.5.1 (2017-11-17)

  • Argument --fields was added. You can use it to specify which fields should be printed to stdout. By default, all fields are printed.
  • Fixed error with parsing entries where fields contains time key with non string value.

0.5.0 (2017-11-14)

  • Now jsail searches fields dict not only in key @fields, but also in fields.
  • Fixed precendence of fields searched for item’s timestamp. Previously, item found in @timestamp can be overwritten by value from time. Now these fields are searched in this order and first found value is used:
    • @timestamp
    • timestamp
    • time
    • (@fields | fields).timestamp
    • (@fields | fields).time

0.4.0 (2017-05-18)

  • Unbuffered stdin usage was fixed and now program exists correctly if it encounter EOF.

0.3.0 (2016-10-03)

  • Now jsail recognizes as timestamp keys timestamp, time, @fields.timestamp, @fields.time. And similarly, for message these keys are checked: message, msg, @fields.message, @fields.msg.
  • Now jsail quietly skips lines which can’t be parsed as single JSON document.

0.2.1 (2016-03-13)

  • Fixed issue with STDIN bufering. Previously, input given from STDIN was buffered and sometimes jsail didn’t show content until buffer fills up. Now this behaviour is fixed.

0.2.0 (2015-07-06)

  • ‘anyjson’ was added into the requrements list.
  • Now jsail will process STDIN if filename wasn’t given as a command line argument. This makes possible to use it in unix pipelines.

0.1.0 (2015-04-16)

  • First release on PyPI.
