0.5.0 Release Notes

Bosun

This is our first non-preview release in 9 months and includes significant changes since 0.4.0. Future releases should be at a quicker pace since this release involved a complete refactor of Bosun's internal storage.

  • We have moved Bosun's internal storage from purely in-memory (that was seralized to bolt) to redis/ledis and refactored the code to be more incident based. In 0.4.0 the dashboard could take 10-30 seconds to load at times. It now should not take more than a second under normal conditions, and should be even faster in a future release. This also results in faster startup times for Bosun and other performance improvements
  • Deprecated the logstash queries and replaced them with more generic elastic functions. This supports different time formats, index naming schemes, and adds more search possibilities
  • Added support for basic series operations. Before wit

Previewing Puppet ERB Files with JSON Datasource from Commandline
Based on the idea in this SO answer: http://stackoverflow.com/a/30037886/107156
1) Create a ruby file to contain the variables
2) when running erb, important that file as a library
Notes:
- The .rb file must have all variables that you call methods on (i.e. `any?`) or you will get a nilClass error.
- The switch to -r doesn't have the .rb extension on it, but the file does
