Sebastian has written a prototype gRPC plugin which allows to interact with collectd in a manner similar to the UnixSock plugin. Looks like Sebastian is hoping for C++ experts to jump on the project, so reach out to him if you're interested in cleaning up / extending this plugin!
 
gRPC plugin for collectd

So, the inevitable has happened: I hacked a gRPC plugin for collectd, currently allowing to dispatch and query (list) values. I think it nicely demonstrates how things work and is easy to extend to support more features. Anyway, I'm sure there are a few things that could be cleaned up on the C++ side (I'm not very good friends with that language). I'm hoping that someone else will pick it up from here ;-)

As a nice side-effect, the change introduces support for C++ and protocol buffers to collectd and the build system. Also, it provides a more complete example of an asynchronous gRPC server than the examples shipped along with the upstream project.

Gone amongst the Gophers? Check this out!
 
I've spend some time implementing the binary network protocol in the collectd Go API last week. The implementation provides support for both, client and server, and also implements the encryption / signing of metrics.

The different parts are designed so that they "fit together" well, making it very easy to write proxy servers and the like. Take a look at the examples for the "ListenAndDispatch()" function …

The project is currently still very much a work in progress – beware of stuff moving around. In this early stage, I'd especially welcome feedback since it's still easy to make changes.

Package network implements collectd's binary network protocol.

Awesome, logstash 1.3 comes with support for consuming +collectd metrics!

The Hackathon was a huge success, and this is one of the outcomes. Enjoy :)
 
Put some +collectd hackers into a room, supply them with coffee and internet and they may start being creative. And then +Pierre-Yves Ritschard ends up embedding Riemann into collectd. How I love free software!

We're proud to announce that collectd 5.5.0 has been released. This version comes packed with new features. Here's merely a short summary, for the full list see https://collectd.org/wiki/index.php/Version_5.5 – you can download the tarballs from https://collectd.org/download.shtml

New plugins allow collectd to read metrics form #Ceph and #DRBD (both distributed file systems), #OpenLDAP and Apache #Zookeeper . On the hardware side, there are new plugins for reading barometers, #SMART data from hard drives and C-states (idle states) from Intel CPUs. From the operating system we now get information on file handles and shared memory.

Integration with other systems has also been improved, there are new plugins to write collectd metrics to Apache #Kafka , a distributed message queue, #Sensu , a popular monitoring solution, and #OpenTSDB , a distributed timeseries database.

Of course, many existing plugins have been extended, too. For example, CPU usage can finally be reported as a percentage, rather than jiffies. This was one of our most-requested features.

Huge thanks to all of our contributors – you are awesome!
Version 5.5 has been released on Wednesday, May 27th 2015. This version is currently supported. Changes. Release 5.5.0. Changes since 5.4.0 up to 68923fc (NB: doesn't include bugfixes which are already in the release branches). Build system: Ability to make out-of-tree builds has been fixed.

FYI, collectd-tg (collectd traffic generator) can be used to stress test collectd server setups. It's part of the standard source tarball.
 
Interesting blog post by +Aaron Mildenstein about the new #collectd codec in #Logstash 1.4.1. It works with the (also new) UDP input which is multi-threaded. The result is a >10x performance improvement.
With the advent of Logstash 1.4.1, I wanted to make sure everyone knows about the new collectd codec. In Logstash 1.3.x, we introduced the collectd input plugin. It was awesome! We could process metrics in Logstash, store them in Elasticsearch and view them with Kibana.
