Kamailio Exporter For Prometheus In Golang

Via social media media, I noticed a nice article about a Kamailio exporter for Prometheus written in Golang:
So I thought sharing it further via Kamailio’s website. Lately I noticed an increase of interest on using Prometheus, hopefully this exporter tool will help others inside our community.
As a matter of fact, one of the submissions for the next Kamailio World Conference (May 608, 2019, in Berlin) is about using Prometheus with Kamailio for visualising statistics and other metrics via Grafana dashboards (to avoid any confusions, it is not from the author of the linked article in this text). The schedule of the event is expected to be published in the near future, meanwhile you can view a selection of accepted speakers. Early bird registration is still open, if you want to benefit of the discounted access, hurry up to register!

Kamailio World 2019 – First Group Of Speakers

With slightly more than two months and a half before the start of Kamailio World 2019, we are glad to announce the first group of speakers. Their details are available at:
The selection procedure is ongoing, therefore expect the details for other speakers to be published in the near future.
The two interactive sessions present at all the past editions return in 2019, respectively VUC Visions and Dangerous Demos. In addition, we will have at least two other similar sessions to allow better interaction between Kamailio developers and the participants. As usual, expect presentations that go beyond Kamailio, covering Asterisk, FreeSwitch, VoLTE/IMS, WebRTC or IoT and technologies such as blockchain, containerisation and artificial intelligence.
To facilitate more networking between attendees, the 2019 edition is adding a new social event in the evening of the 6th of May, a boat trip on the channels of the city center.
The registration is open, you can do it now to benefit of the early registration price:
Looking forward to meeting many of you at Kamailio World Conference, May 6-8, 2019, in Berlin, Germany!

Kamailio – Open Source Excellence Award At SimCon 2019

We are delighted to announce that Kamailio project was awarded the “Open Source Excellence” prize at SimCon 2019, ceremony hosted by Rachel Riley (twitter – wikipedia) and Simon Woodhead (twitter).
Kamailio were awarded ‘Open Source Excellence’, a key reason being the superb management of the project. Kamailio is used within huge networks and really is the secret weapon of many modern telcos. It is open source and, in the judges’ opinion, one of the best run projects around.
This recognizes the enormous effort made over more than 15 years by the development team and the community to keep Kamailio at the top of open source SIP/VoIP server applications, with a well defined development process and project organizing procedures.
With key targets such as flexibility, robustness, security and scalability, Kamailio continued to bring constantly a consistent set of new features with each major release (19 of them, from SER 0.8.x to Kamailio 5.2.x) and consolidated the trust in being a reliable application that can be used from start-ups to large established telcos and mobile operators.
It is actually a double celebration, because Fred Posner (twitter), one of our most prominent community members and advocate, was also awarded — citing: a genuine ‘Pre-Posthumous Legend’, a selfless, long standing contributor and supporter of the open-source community who has never sought the limelight.
Thank you SimCon for the award and Simwood for supporting the project for so many years!
We look forward to Kamailio World Conference 2019 and hoping to meet many of you there!
Thanks for flying Kamailio!

Fosdem 2019 Remarks

Fact that open source development is huge nowadays couldn’t be felt better than at Fosdem 2019, practically during the first day was almost impossible to move around even on the corridors. It is irrelevant to say that I gave up quickly in the morning trying to attend any session, after failing to find seats in two of the rooms I wanted to get in.
Therefore the first day resumed to hallways, expo areas and cafeterias, meeting and chatting mainly with fellow Kamailians and VoIP/RTC folks. I got also the chance to see again and catch up with couple of other projects and organizations, among them: FSFE, OSI, SFC, the main Linux distros, Fossasia or GSoC.
Back to real time communications, being again being again part of organizing team for the DevRoom and the lounge…
The lounge was available during the both days, as usual filled with many XMPP projects and devs, joined by the Matrix.org team. The SIP/VoIP folks were never attracted by the lounge during all these years, but we always had a stronger presence in the DevRoom.
The RTC DevRoom took place in building H, with a fair large space accommodating about 150 seats, allowing us to run smooth during the day. I haven’t done much on Sunday apart of helping around and chatting with folks just outside.
Henning gave a presentation on what’s new lately on Kamailio project. Asterisk, Matrix, Homer SIP Capture, reSIProcate and CGRateS had their usual presentations as well and WebRTC was also a relevant stake of the day. A new comer this year was the sip3.io project, another SIP capture and troubleshooting tool. Of course, some presentations were about XMPP, open source devs doing a lot of cool stuff with that protocol as well.
On Saturday, we had our informal developers meeting about Kamailio, among participants, besides myself (Daniel-Constantin Mierla), there were Henning Westerholt, Federico Cabiddu, Alexandr Dubovikov and Dragos Oancea. Four were also at the developers meetup in Dusseldorf and we agreed that was something very productive and we should do it again. Couple of ideas were discussed about short term development, more to be announced via mailing lists.
The top of the event was as usual the dinner, done by Kamailio project every Fosdem edition since 2009 (see who was there 10 years ago). Like in the past few years, we were joined by other VoIP devs participating in the DevRoom, being nearly 40 participants (to give few more names: James Body, Tim Panton, Dan Jenkins, Daniel Pocock, Joachim Vanheuverzwijn). Lot of fun and interesting discussions!
Big thanks to Voxbone.com for sponsoring it and to Torrey Searle for helping to organize the dinner!
And to attract more of you to contribute to open source (and Kamailio), I have to mention that I got one of the most amazing gifts in more than 17 years of OSS development: home made Belgian chocolate truffles, amazing taste (thanks Joachim/Zoiper)!
Till the next Fosdem, I am looking forward to meeting many of you at the next Kamailio World Conference, May 6-8, 2019, in Berlin, Germany! Registration is open!
Thanks for flying Kamailio!
