@Kami Kami released this 29 Jan 14:18
v2.1.18
0f0b72a

Improvements:

  • Add new tcp_request_parser and tcp_message_delimiter config option to the syslog_monitor. Valid values for tcp_request_parser include default and batch. New TCP recv batch oriented request parser is much more efficient than the default one and should be a preferred choice in most situations. For backward compatibility reasons, the default parser hasn't been changed yet.
  • Update agent to emit a warning if k8s_logs config option is defined, but Kubernetes monitor is not enabled / configured.
  • Update Kubernetes and Docker monitor to not propagate and show some non-fatal errors.
  • Field values in log lines for monitor metrics which contain extra fields are now sorted in alphabetic order. This should have no impact on the end user since server side parsers already support arbitrary ordering, but it's done to ensure consistent ordering and output for for monitor log lines.
  • Update agent to throw more user-friendly exceptions on Windows when the agent doesn't have access to the agent config file and Windows registry.
  • Update code which periodically prints out useful configuration settings to also include actual value of the json library used in case the config option is set to "auto".

Bug fixes:

  • Fix a race condition in docker_monitor which could cause the monitor to throw exception on start up.
  • Fix a config deprecated options bug when they are set to false.
  • Fix agent so it doesn't throw an exception on Windows when trying to escalate permissions on agent start.
  • Make sure we only print the value of win32_max_open_fds config option on Windows if it has changed.
  • Fix a bug which could result in docker, journald and windows event log checkpoint files to be deleted when restarting the agent. This would only affect docker monitor configurations which are setup to ingest logs via Docker API and not json log files on disk (aka docker_raw_logs: false docker monitor option is set).
  • Fix a small bug which might skip first lines of the worker session log file.

Other:

  • Pre-built frozen Windows binaries now bundle and utilize Python 3 (3.8.7). In the past releases, they utilized Python 2.7, but due to the Python 2.7 being EOL for a year now, new release will utilize Python 3. This change should be opaque to the end user and everything should continue to work as it did in the previous releases.
