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 metrics endpoints Introduction Quick intro OpenMetrics Outro Problem statement Goldrush So about fragmentation... Cloud native is in the buzz phase Explosive growth always equals goldrush and stake claiming, aka fragmentation Quick intro OpenMetrics Outro Plans Beyond cloud OpenMetrics is intended to go beyond ”just” cloud-native fields Want to get more traditional projects and vendors on board Arista already on board Vertiv

Prometheus is a pull-based system Black-box monitoring: Looking at a service from the outside (Does the server answer to HTTP requests?) White-box monitoring: Instrumention code from the inside (How much time Supports dozens of data sources Modern UI Allows for complex data manipulation and visualization Native Prometheus support New feature: Interactive exploration of Prometheus data Richard Hartmann & Frederic

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 monolithic application ...why? Richard Hartmann & issues Some bugs and some human mistakes in the release process Always running latest is the cloud-native approach, but this is still not acceptable ..especially if every single version has its issues

 … ⻩黄⾦金金指标 业务指标 少量量事件

mysql_slave_status_slave_sql_running == 0 and ON (instance) mysql_slave_status_master_server_id > 0 这个promql想表达的意思是如果这个mysql实例是个slave（master_server_id>0），则检查其 slave_sql_running的值，如果slave_sql_running==0表示slave sql线程没有在运行。 sql线程没有在运行。 但是mysql_slave_status_slave_sql_running和mysql_slave_status_master_server_id这两个 metric的标签可能并非完全一致，不过好在二者都有个instance标签，且相同instance标签的数 据从语义上来看就表示一个实例的多个指标数据，那就可以用on关键字，指定只使用instance 标签做匹配，忽略其他标签。
