#monitoringlove hackfest

The age of #monitoringsucks is over, we're now transitioning into a #monitoringlove period.

That however doesn't mean al the work is done, we still need to do a lot of work and a lot of people are working on a lot of stuff.

Therefore like last year we are opening up our offices again right after Fosdem for a #monitoringlove hackfest

That's right on february 4 and 5 a bunch of people interrested to fix the problem will be meeting , discussing and hacking stuff together in Antwerp. In short a #monitoringlove hackathon

Inuits is opening up their offices for everybody who wants to join the effort Please let us (@KrisBuytaert) know if you want to join us in Antwerp. We'll provide caffeine, wireless, chairs and some snacks.

Please register upfront at :

Obviously if you can't make it to Antwerp you can join the effort on ##monitoringsucks on Freenode or on Twitter.

The location will be Duboistraat 50 , Antwerp
It is about 10 minutes walk from the Antwerp Central Trainstation
Depending on Traffic Antwerp is about half an hour north of Brussels and there are hotels at walking distance from the venue.

Plenty of parking space is available on the other side of the Park

Read last years report to get an idea of what will happen...

PS. Yes I`m trying to get another event of the ground the days before Fosdem but I`m still awaiting confirmation of the venue ..

Linuxcon Europe, Barcelona

I`m in Barcelona this week for LinuxCon Europe ..
I`ll be hosting 3 sessions this week.

Today I`ll be helping Sebastien Goasguen with his session Building Foss Clouds, I`ll be talking about how to use tools such as Puppet, Graphite and Icinga to monitor your clouds. Sebastian inherited the Building FOSS Clouds tutorial last week and asked me to help out.

Tomorrow I`ll be giving my 11 Open Source Tools for your Devops Stack talking.

And on thursday I will be giving a more general "What's this #devops thing anyhow" talk during the Cloudstack event following LinuxCon.

Gentwerpen Devops Meetup & Conference Season Update

A couple of us have been taking about it a lot already .. we wanted to host a one day #devops event in .be already last year.. then talks about starting a meetup group started again with @wonko_be but it was @fs111 pushing the final button and calling the rest of the .be community to order, we've set a date
and the first session will take place (agenda still needs to be detirmined)

So all you Belgian devops enthousiasts, maark October 11th in your calendar and go register here

We already have 2 other venues (Gent, Boom) lined up .. but let's get this first one started :)

Next to that here's an update for the rest of my upcoming Conference Season :

  • Later this month I`ll be heading to San Francisco for a talk at PuppetConf 2012. I'll probably be around in the valley a bit earlier so if you anyone wants to meet up I`m open for suggestions.
    (Yes I asked Nick Stielau of Pantheon to host a #monitoringsucks / #devops meetup about Sensu but I should have predicted it was about to clash with the PuppetConf speakers dinner :((
  • I was thinking to swing by the MySQL- Connect conference but given the pricetag I don't think I`ll bother ... I am however thinking about crashing the hallway track , or tricking the Foreman Meetup to be colocated with a MySQL event again just like at Fosdem earlier this year
  • I will be attending the Jenkins User conference in San Francisco however before flying back to Europe
  • If you haven't noticed yet , Devopsdays is going to be in Rome this year on october 5 and 6. Registration
    is still open !
  • During the last weekend of october it's time for again. No news on the program yet.
  • And one week later I`ll be heading to Barcelona to speak at LinuxCon Europe I`m really looking forward to that last one again as it looks like the good old LinuxKongresses in Germany .. deep technical topics !

Vagrant and Drupal, a winning team

While heading back home from DrupalCon Munich after 4 days of good interaction with lots of Drupal folks.
I realized to my big suprise that there are a lot of people using Vagrant to make sure that developers are not working on platforms they invented their own. Lots of people have realized that "It works on my computer" is not something they want to hear from a developer and are reaching out to give them viable solutions to work on shared and reproducible solutions.

There were 2 talks proposing solutions to the problem,

the first one was ..Fearless development with Drush, Vagrant and Aegir by Christopher Gervais He talked about Drush VAgrant Integraion and how extentions to Drush allow for easy vagrant integration , bridging this gap allows rupal developers to use a tool they are already familiar with

The second one was Jochen Lillich who explained how he us using Vagrant an Chef for this purpose his talk titled Use datacenter tools to make your dev life easier has been posted already.

During the Vagrant BOF , I briefly ran over @patrickdebois old slides on Vagrant after which people started discussing their use cases.. 2 other projects came up

First is Project Oscar which aims at providing developers with a default Drupal development environment in a Jiffy. they do this by providing a bunch of puppetmanifests that sets up a working environment.

And the second one is Ariadne which is a standardized virtual machine development evironment for easily developing Drupal sites in a local sandbox that is essentially identical to a fully-configured hosted solution. It attempts to emulate a dedicated Acquia/Pantheon server as closely as possible, with added development tools. Project Ariadne is just like the examples from Jochen Lillich based on Chef

With all of these tools and examples around , there should be no excuses anymore for Drupal developers to hack on their own machine and tell the systems people "It works on my machine" (let alone to hack in production).

Open Source Certification , Friend or Foe

With 2 of the bigger Open Source projects I care about talking about certifications programs questions pop up again ...

Should we certify ourselves ?

So let me tell you about my experiences in getting Open Source related Certifications ..

Over a decade ago, (2001) when RedHat was still Redhat and not yet Fedora the company I was working for was about to partner with RedHat and needed to get a number of people certified for that.

So I took the challenge, I bored myselve to death during a 4 day RedHat fast track training and set out to do the exam the next day. Obviosly I scored pretty well given my yearlong experience in the subject. Back then I was told that I scored the one but European Record on the exam which was actually held by another collegue (hey Ico) , our CTO however was not amused when I told that I could have scored better but I didn't bother running a chkconfig smb  on since I didn't see the use in using windows fileshares in a unix environment (Yes I was young , we're all allowd to make stupid mistakes :))

So I was certified, we were expecting the requests to flow in en masse ... nothing happened... not a single customer request... If I recall correctly we got 2 requests for certified engineers over the course of the following years. One was from a customer that wanted to have us do some junior level sysadmin work on their systems which we didn't care about, we proposed a more junior profile, but they insisted on having someone who was certified, The other one was from a Large institution that wanted certified people for their RedHat support, only to quickly learn that the budget they had planned for this project was about half the rate we usually charged ..

When RedHat introduced their certified Architect program my answer was, sure .. if you bring us the customer that will make the investment worthwhile , guess what..

My second experience with Open Source certification came a couple of years later with MySQL, same story partnering etc, . only this time our trainer had put some focus on a couple of slides during the training (Hi Tobias) and during the exam indeed one of those questions popped up, The correct answer to "What are the core values of MySQL AB" was "We reply to email" , I stood up and left the exam ...
I ranted about this to a number of people including Roland Bouman who back then was just starting on the MySQL (NDBD) Cluster certifciation track and I assisted him in making the book to study for that exam better.
Once again .. pretty much no one asked for MySQL certification in Europe back in those days (2007 ?)

I won't go deeper into discussing the Xen certification I got from Citrix, but it involved correcting slides from the presenters at the first European training.

Based on my experience with these certifications in Belgium/Europe you can see that I`m not a big fan of certifications I have not seen a reason for me to certify yet

I actually think that noone within the Open Source community should be looking for certification, we should be looking for people that are active in the community and that are contributing to projects.
Unlike in the proprietary world where you have to cough up tons of money in order to get a license to play with a tool and learn itl In the open source world with projects such as both Drupal and Puppet, there are absolutely no excuses for Junior people not to engage and prove themselves. they have full access to anything they need, the only thing they need to do is want to get involved.

Sadly this world however is still full of incompetent recruiters, middlemarket agencies that will never understand this and will ask for cerftifications of some kind. My fear is indeed that there will be a group of mediocre but certified developers swarming these growing markets at dumping rates and that the people with the real experience that have been involved in the communities for ages already will be the ones pulling the short straw.

Anyhow ... in just a short couple of years everything will be fine again .. as by then my RHCE will be current again and the incompetent recruiters that need people that are RedHat 7 certified will start calling me by the dozen.

Our #monitoringsucks rpm is repository available

Not only our Rubygems Builds have changed, but also my internal #monitoringsucks repository.

You might have noticed a variety of vagrant- projects on my github acount,
Being the #monitoringsucks part of them. All of those Vagrant projects are basically my test setups to play with those new tools.

They contain a bunch of puppet modules that install and configure these tools. (Note that they mostly consist of
of git submodules to other puppet module repositories.

Given the fact that I also like to have my software cleanly installed from a package, that means that some of these tools had to be packaged, or I had to create a personal / internal repository which had packages from upstream that were hiding on the internet available.

I've forked of this repository off the internal Inuits epository so you all can also benefit from these efforts.
(You gotta love pulp :))

That means you can now install all of the above mentionned #monitoringsucks tool from our public repo on

  1. yumrepo { 'monitoringsucks':
  2. baseurl => '',
  3. descr => 'MonitoringSuck at Inuits',
  4. gpgcheck => '0',
  5. }

Patches to both the Vagrant projects and the puppet modules are welcome ...

Ruby Gems Yum Repo

For those of you that are looking for my old build-gems Github repo, given that lots of other Inuits collegues are using it too I've transferred ownership of that repo to the Inuits group.

It can now be found on (Yes directory indexes are disabled on purpose..)

The build result has also been moved. We've replaced our static with a Pulp powered yum repo.

The new location of the rubygems rpm repo now is at

Which can be used as

  1. [rubygems]
  2. name=RubyGems at Inuits
  3. baseurl=
  4. gpgcheck=0

or even

  1. yumrepo { 'rubygems':
  2. baseurl => '',
  3. descr => 'RubyGems at Inuits',
  4. gpgcheck => '0',
  5. }

More repos are moving .. I`ll be updating Vagrant trees as I go ..

Breaking the Silence.

3+ months is probably the biggest timeout I've taken from blogging in a while..
Not that I didn't have anything to write ..but more that I was prioritizing writing different content over
over writing blogposts.

Blogging tech snippets and contributing documentation used to be one now all of that has evolved.
Anyhow ..

So to get things going here's my preliminary Conference schedule for the next couple of months.

  • First up, in about one week (august 20-24) I`ll be chairing the #devops track at DrupalCon Munich
    Next to talking there myselve explaining the Drupal Crowd what devops is
    Plenty of interresting content there ranging from culture over to tooling and back. I`m really looking forward to this one.

    There's also talk of the local Devops meetup group hosting an additional meetup !

  • About a month later I`ll be heading to San Francisco for a talk at PuppetConf 2012. I'll probably be around in the valley a bit earlier
    so if you anyone wants to meet up I`m open for suggestions.
  • I've taken over a bit of Patricks workload this year , thus I`m trying to guide the local crew in Rome into organising yet another awesome Devopsdays Europe,
    If you haven't noticed yet , Devopsdays is going to be in Rome this year on october 5 and 6. Both registration and the call for participation are still open !

Next up .. content ... on how monitoring tools still suck .. and I`m still not sure wether a certification program is relevant for open source consultants ..

Devops in Munich

Devopsdays Mountainview sold out in a short 3 hours .. but there's other events that will breath devops this summer.
DrupalCon in Munich will be one of them ..

Some of you might have noticed that I`m cochairing the devops track for DrupalCon Munich,
The CFP is open till the 11th of this month and we are still actively looking for speakers.

We're trying to bridge the gap between drupal developers and the people that put their code to production, at scale.
But also enhancing the knowledge of infrastructure components Drupal developers depend on.

We're looking for talks both on culture (both success stories and failure) , automation,
specifically looking for people talking about drupal deployments , eg using tools like Capistrano, Chef, Puppet,
We want to hear where Continuous Integration fits in your deployment , do you do Continuous Delivery of a drupal environment.
And how do you test ... yes we like to hear a lot about testing , performance tests, security tests, application tests and so on.
... Or have you solved the content vs code vs config deployment problem yet ?

How are you measuring and monitoring these deployments and adding metrics to them so you can get good visibility on both
system and user actions of your platform. Have you build fancy dashboards showing your whole organisation the current state of your deployment ?

We're also looking for people talking about introducing different data backends, nosql, scaling different search backends , building your own cdn using smart filesystem setups.
Or making smart use of existing backends, such as tuning and scaling MySQL, memcached and others.

So lets make it clear to the community that drupal people do care about their code after they committed it in source control !

Please submit your talks here
