Naemon/Nagios: LXC check resources

2 September 2014 in Debian, Developement, Hi-Tech, Linux, LXC, Nagios

You may know that I really like LXC and the major problem when you want to use that solution in production is: how do you monitor memory and CPU? Regarding the CPU side, I do not have an easy answer for the moment :-(. However regarding the memory, I’ve made a Nagios/Naemon check which will check the memory (RAM) and SWAP of a container. Here is how to use it:

Nagios/Naemon: Free Mobile SMS notification

27 August 2014 in Debian, Hi-Tech, Linux, Nagios, Web

Thanks to Free Mobile (French mobile provider) to provides an SMS API. I enabled it for my own monitoring escalation, just in case I have problem receiving emails. I’ve made a short documentation on how to setup SMS notification through Free Mobile for Nagios or Naemon (in french). Enjoy :-)

Monitoring: switching from Nagios to Naemon (not Shinken or Sensu)

25 August 2014 in Debian, Hi-Tech, Linux, Nagios

I am using Nagios for about 8 years now for personal and professional usage. What I can say is, this is a super product, old and stable but not as scalable as I would like. We’re in the age of Cloud computing and in my opinion we shouldn’t have to take care about backup and monitoring in now days, this should be automatic. I was searching a solution for my personal usages, that’s why I first wanted a lightweight solution but with enough maturity to auto discover my newly created LXC containers.

OMG, Nagios OpenSource project is almost dead !

31 October 2013 in Hi-Tech, Nagios

This is not a really good news. An announcement at OSMC (Open Source Monitoring Conference) as been made by Andreas Ericsson ( Nagios 4 core dev) about the future of Nagios. Nagios 4 is the latest Core version of the project ! Only the enterprise version will remain (strategic choice of Ethan, the creator). A Nagios 4 fork will appear called Naemon and developed by Andreas Ericsson. I remind as well that the Shinken is a real good alternative and is able to work with your current Nagios configuration.

How to install and configure a monitoring machine for a supervision screen

20 August 2013 in Debian, Hi-Tech, Linux, Nagios

The goal of this documentation is how to quickly setup a monitoring screen machine for Nagios/Shinken. Several times in several company I had to do that kind of thing. On Mac OS and Linux. I finished to create a documentation for the next times I’ll have to deploy such things. The idea is to have a machine that nobody never touch once installed. It’s always boring to plug a keyboard and a mouse when somethings goes wrong on this kind of machine that you normally never have to touch.

Linux Magazine sur Shinken

28 January 2013 in Debian, Hi-Tech, Linux, Nagios, Puppet

Je suis un fidèle lecteur de Linux Magazine et me suis récemment abonné à leurs journaux en PDF (enfin ! Marre des piles de Linux mag qui traînent chez moi). Même si j’aime beaucoup ce que ces magazines proposent, tout ne m’intéresse pas et je dirais que c’est normal. Cependant ils font de temps en temps des hors série sur un sujet bien particulier qui permet de découvrir de nouveaux horizons.
