Goat Willow

2.0.0 "Goat willow" is the third major release of Willow. The major version was updated because this release now requires Java 8 and the end user and deployer connectivity ports were separated and that will require configuration changes for all users.

Java 8 is now mandatory because Jetty, our http server requires it. Java 7 has been without public updates since April and Java 8 is widely available.

User interface and deployer connection ports were separated to enable setups where each are protected through different network level solutions.

Other notable features are:

• Custom radiator configurations can now be downloaded
• HostInfoSender can now be configured to send the IP of a named interface. Enables reliable resolving of a nodes IP address for SSH connectivity
• Several UI tweaks and bugfixes

Coyote Willow

1.2.0 "Coyote Willow" is the second major release of Willow with lots of fixes and improvements. A lot of effort was put into making the build better and provide code coverage from all tests (unit- as well as integration tests). We now use four major static code analysis tools (Sonar, Findbugs, CPD and Coverity on demand). We now have a framework for measuring what gets tested and running relatively comprehensive integration testing and in future versions we'll work on getting this coverage to an acceptable level.

Feature highlights in 1.2.0:

• Initial java 9 support
• Event handling framework (will be refactored for the next version)
  • Includes sending emails from any configured event including exceeding thresholds
• Host specific graphs update in realtime
• PTQL statistics sender sends data from any process seletable with PTQL
• Flame graph component draws live stack visualization
• Child statistics pollers now poll all children by default
• Implement private key authentication in addition to the existing ssh-agent
• Script to do T3 model visualization from the source
• Date format for long timescales now shows when the day changes
• Titles for host detail graphs
• Refactored elasticsearch to connect to an external cluster when clusterName is defined
• Close button to all graphs
