It is no secret that we use Mattermost at Faelix — after all, it is a product we already support to be able to offer it to our customers. And like many network operators we use Oxidized to track and log changes to our routers and switches, even when those changes are made by automation tools.

As part of our move to using more ChatOps within the business I wanted to get visibility of network changes within our network operations channel in Mattermost. A quick and dirty script achieved this.

Open source, well Integrated, welcoming community, plethora of features, intuitive design, cross platform nature and easy extensibility make this one of the best collaboration tools out there. No distractions, god sent features like Makdown, streams, topics, bots, integrations... the complete package.
