官网文档说的很清楚了,而且有架构图,拜托动动脑子:

agent(可能是categraf、telegraf、Grafana-agent、datadog-agent)往LB写,LB后面是多个n9e-server,这多个n9e-server使用相同的ClusterName,组成一个集群,如果某个 n9e-server 挂了,LB会自动踢掉。

假设一个机房500台服务器,需要多少个n9e server呀?

没啥前提条件,让人怎么回答,,,n9e-server部署在1c1g的机器上,跟部署在128c256g的机器上性能能一样么?!千兆网卡、万兆网卡能一样么?!

这个问题完全可以测出来,先部署100台agent看看n9e-server的机器的各项性能指标,如果很宽松,继续部署不就完事了,每个环境不同,自己的环境的测试结果显然是最靠谱可信的!
