- 是一个时序数据库,主动取拉取数据. 这与influxDB不通(需要别人主动push数据给他)
- prometheus决定取哪些数据,以及取数据的频率
- Grafana或Kibana来实现数据可视化
Prometheus在收集数据时采用的’Pull’模型(服务端主动去客户端拉取数据). 而Zabbix等传统监控采用的’Push’模型(客户端发送数据给服务端)
Pull模型在云原生环境中有比较大的优势,原因是分布式系统中,一定是有中心节点知道整个集群信息的,那么通过中心节点就可以完成所有要监控节点的服务发现,去拉取数据就好了!
Push模型倒是省去了服务发现的步骤,但每个被监控的服务都需要内置客户端,还需要配置监控服务端的信息,这加大了部署的难度,Push模型在OpenStack和Kubernetes等环境中用的不多.
