To start this year’s series of contribution to the open source community, we’re proud to announce the release of yet another tool that we use to monitor our production setup, namely a Prometheus metrics exporter for the Dovecot POP/IMAP mail server. If your email setup is also based on Dovecot and use Prometheus for monitoring, we’d like to invite you to give this exporter a try.

Kumina can look back on a successful year. A lot happened at Kumina these past 12 months. We carried out challenging new projects and started new collaborations with amazing organisations. Behind the scenes, we worked hard on optimising and extending our services. We also welcomed new colleagues at our team. Read everything about the latest developments at Kumina in 2016 and about our future plans.

Today we’re happy to announce that Birdwatcher is now available on ​our company’s GitHub page. Birdwatcher accesses Calico/BIRD metrics through Prometheus. If you’re a user of both Calico and Prometheus, be sure to give it a try. Enjoy!

Kumina is sponsoring CloudABI: CloudABI is a UNIX-like programming environment for Linux and the BSDs that allows you to easily design sandboxed applications. It accomplishes this by making strong use of capability-based security, inspired by the University of Cambridge’s Capsicum. Compared to traditional UNIX applications, CloudABI applications are better resistent against security vulnerabilities, easier to test and easier to maintain. CloudABI is available as Open Source Software, free of charge.

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.
