Kumina presentatie over het monitoringsysteem Prometheus bij de voorjaarsconferentie van NLUUG

April 18th, 2017

Dinsdag 16 mei geeft één van onze medewerkers, Ed Schouten, een presentatie over het monitoringsysteem Prometheus op de voorjaarsconferentie van NLUUG. Kumina past Prometheus toe als monitoring systeem voor haar klanten en heeft diverse exporters (plugins) voor Prometheus ontwikkeld. In de presentatie vertellen we je meer over dit schaalbare en moderne monitoringsysteem. We beantwoorden de volgende vragen: Wat is het datamodel van Prometheus? Hoe komt Prometheus aan zijn data? Hoe raadpleeg ik de data en hoe werkt de querytaal? Hoe genereert Prometheus alerts? En natuurlijk uitleg over hoe wij binnen Kumina Prometheus gebruiken. De speker, Ed Schouten, focust zich bij Kumina op het uitrollen van Kubernetes en Prometheus als vervanging voor de bestaande infrastructuur in Linux-clusters. Hiervoor werkte hij tussen 2012 en 2014 voor Google als Site Reliability Engineer, hier deed hij uitgebreide ervaring op met Borg en Borgmon, waar Kubernetes en Prometheus op gebaseerd zijn.
