OpenNebula is a great enterprise cloud solution and one of its major advantages compared to others on the market is its simplicity. You can start your cloud in minutes and OpenNebula takes care of your compute, storage and network resources. But things can get more complicated running in production. OpenNebula needs an available infrastructure with good-performance to serve all requests in the expected quality. Icinga is great choice to fill this gap by taking advantage of the tremendous number of supported hard- and software. It delivers an easily scalable solution, with clustering, load balancing, automated replication, and even business process monitoring out-of-the-box. Based on a new configuration format with advanced language features – like conditional processing and complex type support – monitoring agile environments works like a breeze. The talk will give a short overview over Icinga followed by a detailed explanation into availability and performance monitoring of favourite cloud compute- and storage-backends. It will provide best practices and precise production examples to keep an eye on your cloud and your 24×7 availability. Author Biography Bernd Erk, is co-founder and project organiser of the Icinga project that has been busy improving the forked Nagios code base since 2009. In his day job as Managing Director of NETWAYS he overseas success and smooth operation of all customer projects and business processes.
