Collector Release Notes

October 31, 2018 (19.227-15)

Local and Remote File Sources on Linux systems now ignore /var/log/(lastlog|btmp|wtmp) binary files instead of ingesting them.
Bug fix: Collecting metrics with a Docker Stats Source could cause high CPU usage.
Bug fix: Added a missing dependency that was causing the Remote Windows Performance Monitor Log Source to not collect logs as expected.

Updated the Collector's cookie management policy to prepare for a receiver change.
Bundled JRE version upgraded to 8u181.

Bug fix: When configuring Docker Sources without environment variables or labels null pointer exceptions were not handled appropriately.
Bug fix: Remote File Sources were scanning from the current directory instead of the root directory when using leading wildcards in paths.

Docker Stats Source can now be configured to ingest metrics time series instead of JSON log messages. See Docker Sources for details.
Bug fix: Local and Remote Log File Sources were not immediately detecting new or modified files in certain nested directory structures when a wildcard was used in the path expression.
Redundancy file added for Source configurations to prevent possible re-ingestion of data.

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.

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.
Upgrading Collectors without administrator privileges on Windows to 19.216 or higher will require a manual upgrade installation.

Changes to upgrade codepaths in preparation for upcoming release.
Bug fix: Collector unable to start after an upgrade when using a custom installation path on Windows 32-bit.
