Today we’re glad to announce that we’re releasing Buckler as open source software. Buckler is free alternative to Shield, a light-weight proxy for Kibana, written in Python (Django). It allows you to restrict access in Kibana by adding password authentication. When logged in, a user is only allowed to access indices specified for that user in Buckler’s configuration file.

Yesterday, Logstash 1.4.0 was released containing many improvements, one of which was contributed by us. We’ve implemented signature verification and packet decryption in the collectd input plugin. This blogpost will give an overview of how encryption and signing is used in the collectd binary protocol. If you want to implement your own collectd receiver, this is pretty interesting.
