New feature | Local Event Tracing (ETW) Support with Windows Event Channels.

April 25, 2015 (i19.115)

JRE 7 Support. We’ve upgraded to JRE 7, which fixes a potential security vulnerability in JRE 6 (

JRE 7 is now included in the Collector package and is installed automatically during the installation process. This applies to new installations on all platforms except UNIX. For UNIX platforms, you need to install JRE before installing the Collector. The Collector still works with JRE 6, but due to the security vulnerability, we encourage you to use JRE 7 and upgrade to the latest Collector.

Performance improvements for Local Windows Event Collection. Local Windows event logs have been optimized and are now collected faster.

Assigning a custom directory for installation. During installation, the Collector installer automatically creates the needed Collector directories in the default location. If you want to specify a different location than the default top level directory, create your own top level directory before you start the installer, and then select it during the installation process.

Changelog | When collecting Windows Events, if event record IDs were greater than four billion, the Collector could hang on a record ID, causing it to re-collect that record in a loop, causing ingestion delays of more recent events.This issue was due to a 32bit limitation that affected 64bit Collectors. This version of Collector software addresses this limitation, so events with record numbers greater than four billion are properly collected.

New feature | UTF-16 encoding is now supported for Local File Sources.

February 4, 2015 (i19.108)

New Feature | Support for Local Configuration Management. With Local Configuration Management, you can set up and manage all Sources that you’ve set up on a Local Collector using a file that describes each Source’s parameters. The config file then remains on the Collector, and is checked nearly constantly for any changes, making updating Sources a quick process.

New Feature | Support for CPU usage Target.You can now choose to set a CPU Target to limit the amount of CPU processing a Collector uses. This option is applied only to for Local and Remote file Sources.
