Collector Release Notes

  • TLS 1.0 DeprecationTLS 1.2 requirement reminder for Collectors. To keep up with industry standard best practices and ensure the security of our customer data, we are planning to only support TLS version 1.2. Please ensure all your Sumo collector agents are upgraded to version 19.155-X or higher while running JRE 7+ by May 31, 2018.

May 16, 2018 (19.216-38)

  • Bundled JRE version upgraded to 8u172.
  • Bug fix: Misconfigurations in data forwarding could lead to high CPU usage.
  • Bug fix: Extremely large Windows event log entries in an event channel could cause collection to stop for that channel.

May 1, 2018 (19.216-33)

  • Enhanced metadata allowing you to customize sourceCategory and sourceHost with environment variables, labels, and tags. Docker tags welcome, for more information see Collect Logs and Stats from Docker.
  • Metrics support for Carbon 2.0 format has arrived with a new Source, Streaming Metrics. This will support Graphite format as well so our Graphite Source has been renamed. For more information, see Streaming Metrics Source.
  • Data Forwarding is now more reliable for HTTP and Syslog destinations. Data is queued on disk when in-memory fills instead of causing your system to run out of memory. To configure your data forwarding queue limits see Forward Data from an Installed Collector.
  • SystemD is now the default init system on Linux distributions that support SystemD.
  • Simplified installation for the Linux binary package as a result of an updated Tanuki wrapper. For more information, see Install a Collector on Linux.

Known Issues

  • Downgrading from version 19.216 to 19.209 is not supported due to 19.216 having a new Tanuki wrapper.
  • When upgrading from version 19.209 to 19.216 on Ubuntu 16 and above using a shell executable file (.sh), Debian, or the Web UI you will need to manually restart the collector service after upgrading.
