Daemonset is a new resource object in the kubernetes1.2 version that manages only one copy of the pod on each node in the cluster. This usage applies to scenarios where a glusterfs storage or ceph storage daemon process is run on each node. Run a log capture program on each node: Fluentd or Logstach. Run a health program on each node to capture performance data for the node, such as Prometheus Node exportor, COLLECTD, New Relic agent, or ganglia gmo

conditions is almost impossible, and in the second scenario, where the raw data is stored. If you're still using a relational database, then how do you want to index the table? This series of questions leads us to the idea of "creating customized storage, field computing, and the engine that provides query services," which is Prometheus (see Figure 6). Figure 6 The storage structure of the prom As you can see from Figure 6, we have chosen HBase as th

It is best to do grayscale switching and release verification, let some users first use the new application, verify OK after the full amount of switching, such as the new United States in accordance with the Office network and external network to divide user groups. 6. The summary of the new American service Overall, the new United States service is

Currently Grafana supports data sources –es –influxdb –prometheus –graphite –opentsdb –clo

together. The most common nginx (SLB) We use is Tengine 2.1.1, which is deployed on Docker. Q: Since it is the package, the bottom with Mesos than kubernets is not much flexibility, right? A: For the PAAs platform, we want only the resources to dispatch this function, other functions we still want to be able to implement, and Mesos is focused on scheduling resources, and has experienced a lot of levels of testing. And Kubernetes currently provides a lot of services, we do not need,

Rich in functionality, while supporting the external process and container data collection, up to 55 kinds of data source plug-in, there is no need for cloth cadvisor, personal comparison recommended. Students who need to be alerted may consider changing the influxdb to Prometheus. It contains alertmanager to implement email, pagerduty and other message notifications. The data backend can choose
