记录使用项目 clash-exporter 搭建ShellCrash流量监控平台的流程，部署时博主的shellcrash使用的clash meta核v1.18.5

安装clash-exporter

项目release中下载对应平台版本的可执行文件，解压至/opt/clash_exporter

cd /opt/clash_exporter
chmod 777 clash-exporter
./clash-exporter #试运行

报错

failed to dial: failed to WebSocket dial: expected handshake response status code 101 but got 404

原因是监听默认127.0.0.1:9090地址，但是ShellCrash运行端口为9999

vim /etc/profile
export CLASH_HOST="127.0.0.1:9999" # /etc/profile结尾追加

source /etc/profile

再试运行就没报错了

守护进程

设置守护进程需要的环境变量

浏览器打开 http://IP:2112/metrics 确保有输出

安装prometheus

浏览器访问 http://IP:9090 打开 status->Targets 确保clash状态为up

安装Grafana

1

apt install grafana
systemctl start grafana-server

修改Grafana默认端口号

因为Grafana默认端口号为3000，已经被我本机的AdGuardHome占用掉了，所以需要修改一下Grafana端口号为4000

vim /etc/grafana/grafana.ini

[http_server]
http_port = 4000

systemctl restart grafana-server

浏览器打开 http://IP:4000

添加数据源

连接->数据源

添加数据源->prometheus

其他地方不用改，Save &test

添加仪表盘

首页->仪表盘->新建->导入

id 18530 加载

Name随便起

数据源选择刚才添加的prometheus

最终效果

存在的问题是DNS和tracing数据为空，这个没办法，非premium核不支持
