Introduction Quick intro OpenMetrics Outro Problem statement Before Prometheus Only thing approaching a standard: SNMP Who has heard of SNMP? Who likes SNMP? XKCD 927 applies Richard Hartmann, RichiH@{freenode Quick intro OpenMetrics Outro Problem statement After Prometheus Prometheus has become a de-facto standard in cloud-native metric monitoring Ease of exposing data has lead to an explosion in compatible format into its own standard Neutral brand Umbrella for wider cooperation in FLOSS and industry Broadening designer base ensures covering of many/all use cases Official standard (work in progress) IETF

highly dynamic environments in mind It’s the second project to ever join CNCF and the de facto standard in cloud-native monitoring Kubelets, sidecars, microservices, ALL the cloud-native But it’s a member project, IETF RFC, test suite, etc We are writing code in Prometheus and the Python client library https://github.com/OpenObservability/OpenMetrics Prometheus 2.5 has experimental OpenMetrics support There will be an observability sidetrack Long-term goal is one common, modular, well-engineered standard under a new name Richard Hartmann & Frederic Branczyk @TwitchiH & @fredbrancz Prometheus Deep
