Cees-Jan Kiewiet has continued his series covering the use of RecoilPHP and ReactPHP with the second tutorial focusing on the creation of a Munin Node client.

In the previous post we've covered the basics of coroutines. In this post we're going to build a munin-node client specifically to fetch switch port traffic counters. During this post we not just write an munin-node client, we also deal with some domain logic. All code examples contain comments about what is going on and why. There is a lot of knowledge in those as well so be sure to read the comments.

He starts off by talking about his own use of the Munin system to consolidate and manage data from network switches. He then gets to the code, showing the installation of the required packages and some initial Promise setup. He then creates the basic skeleton of the Munin class and adds in the functionality to connect to the node, gather the details and fetching the list of open ports and values. Finally he puts it all together and includes a screencast of the resulting execution.
