Remote Storage of the Prometheus
Objective
Prometheus in the realm of container clouds, there is no doubt that more and more cloud-native components directly provide Prometheus metrics interfaces without additional exporter. Therefore, the use of Prometheus as the whole cluster monitoring program is appropriate. But me
Exporter is an important part of the monitoring system based on the Prometheus implementation, taking on the data collection work, the official exporter list already contains most of the common system indicator monitoring, such as for machine performance monitoring Node_exporter, For network equipment monitoring snmp_exporter and so on. These existing exporter for monitoring, only need very little configuration work can provide perfect data indicator
based on HTTP
Sequential column data push (pushing) via an intermediary gateway
The target server can be implemented through a discovery service or a static configuration
Multiple Visualization and dashboard support
ComponentsThe Prometheus ecosystem consists of several components, many of which are optional:
The main Prometheus server which scrapes and stores time series data
Objective
Prometheus to Kubernetes (monitoring field), such as kubernetes to container orchestration.With the Heapster no longer developing and maintaining and the Influxdb cluster scheme no longer open source, Heapster+influxdb's monitoring scheme is only suitable for some smaller k8s clusters. And Prometheus the entire community is very active, in addition to the official community to provide a series of
