Podcast.__init__: Gnocchi, a Time Series Database for your Metrics

A few weeks ago, Tobias Macey contacted me as he wanted to talk about Gnocchi, the time series database I've been working on for the last few years. It was a great opportunity to talk about the project, so I jumped on it! We talk about how Gnocchi came to

Gnocchi engine optimization

Software speed is relative. After all, it is the result of a set of trade-offs made between the ease of programming and the speed of hardware. The comfort of the developer and its use of multiple abstraction layers has a direct impact on decreasing the cost in time (and therefore

The time of the release arrived. A little more than three months have passed since the latest minor version, 4.1, has been released. There are tons of improvement and a few nice significant features in this release! Most of the principal changes are recorded in the 4.2 release

Gnocchi 4.1 is out

We did it again. A bit more of our usual four months were needed to do it, but Gnocchi 4.1 has been released. This is a great news and another big milestone for the project! As usual, we enhanced Gnocchi and added a bunch of new things that can

Interview

My interview with Cool Python Codes

A few days ago, I've recently been contacted by Godson Rapture from Cool Python codes [http://coolpythoncodes.com/] to answer a few questions about what I work on in open source. Godson regularly interview developers and I invite you to check out his website! Here's a copy of my original

Gnocchi 4 performance

It has been a long time since I have tested Gnocchi [http://gnocchi.xyz] performances. Last time was two years ago, on version 2 [https://julien.danjou.info/blog/2015/gnocchi-benchmarks]. The current version for Gnocchi is 4.0, released a couple of months ago [https://julien.danjou.info/blog/

Gnocchi or Prometheus?

The realm of time series database keeps expanding those last years. Now and then a new contender appears from the fog. People keep asking me about the difference between Gnocchi [http://gnocchi.xyz] and Prometheus [http://prometheus.io]. It's time to content them. Gnocchi and Prometheus are two open source

Using Gnocchi with Docker

I've recently started to look into Docker to build images ready to be used with Gnocchi [http://gnocchi.xyz] in it. I found it would be a great way to distribute a working instance of Gnocchi. To this end, we created the gnocchi-docker [https://github.com/gnocchixyz/gnocchi-docker] repository on

Gnocchi 4 is out

Finally! Four months ago we pushed the Gnocchi 3.1 release and here we are now, release the 4th major version of that timeseries database. A lot happened in the last 4 months.First, as I already wrote about, we moved to GitHub for hosting our project [https://julien.danjou.

OpenStack Summit Boston 2017 recap

The first OpenStack Summit of 2017 [https://www.openstack.org/summit/boston-2017/] was last week, in Boston, MA, USA. I was able to attend as I've been selected to give 3 talks, to help for a hands-on and to animate an on-boarding session. This made sure I was a bit

Gnocchi independence

Three years have passed since I started working on Gnocchi [http://gnocchi.xyz]. It's amazing to gaze at the path we wandered on. During all this time, Gnocchi has been "incubated" inside OpenStack. It has been created there and it grew with the rest of the ecosystem. But Gnocchi (developers)

Scalable metrics storage: Gnocchi on Amazon Web Services

As I wrote a few weeks ago in my post about Gnocchi 3.1 being released [https://julien.danjou.info/blog/2017/gnocchi-3.1-release], one of the new feature available in this version it the S3 [https://aws.amazon.com/s3/] driver. Today I would like to show you how

Sending your collectd metrics to Gnocchi

Knowing that collectd [http://collectd.org/] is a daemon that collects system and applications metrics and that Gnocchi [http://gnocchi.xyz] is a scalable timeseries database, it sounds like a good idea to combine them together. Cherry on the cake: you can easily draw charts using Grafana [http://grafana.org]

FOSDEM 2017, recap

Last week-end, I was in Brussels, Belgium for the 2017 edition of the FOSDEM [http://fosdem.org], one of the greatest open source developer conference. This year, I decided to propose a talk about Gnocchi [http://gnocchi.xyz] which was accepted in the Python devroom [https://fosdem.org/2017/schedule/

Gnocchi 3.1 unleashed

It's always difficult to know when to release, and we really wanted to do it earlier. But it seems that each week more awesome work was being done in Gnocchi [http://gnocchi.xyz], so we kept delaying it while having no pressure to push it out. > A photo posted by

For the last time in 2016, I flew out to the OpenStack Summit in Barcelona [https://www.openstack.org/summit/barcelona-2016/], where I had the chance to meet (again) a lot of my fellow OpenStack contributors there. How To Work Upstream with OpenStack My week started by giving a talk

A retrospective of the OpenStack Telemetry project Newton cycle

A few weeks ago, I recorded an interview with Krishnan Raghuram about what was discussed for this development cycle for OpenStack Telemetry at the Austin summit. It's interesting to look back at this video more than 3 months after recording it, and see what actually happened to Telemetry. It turns

It's again that time of the year, where we all fly out to a different country to chat about OpenStack and what we'll do during the next 6 months. This time, it was in Austin, TX [https://en.wikipedia.org/wiki/Austin,_Texas] and we chatted about the new Newton

Timeseries storage and data compression

The first major version of the scalable timeserie database I work on, Gnocchi [http://gnocchi.xyz] was a released a few months ago. In this first iteration, it took a rather naive approach to data storage. We had little ideas about if and how our distributed back-ends were going to

Profiling Python using cProfile: a concrete case

Writing programs is fun, but making them fast can be a pain. Python programs are no exception to that, but the basic profiling toolchain is actually not that complicated to use. Here, I would like to show you how you can quickly profile and analyze your Python code to find
