Metrics
更直接（希望更好）的统计导出方式。
相关配置
可以在 inbounds 配置中增加一个 metrics 的 inbound
"inbounds": [
{
"listen": "127.0.0.1",
"port": 11111,
"protocol": "dokodemo-door",
"settings": {
"address": "127.0.0.1"
},
"tag": "metrics_in"
}
]
在路由配置中增加针对 metrics inbound 的路由规则
"routing": {
"rules": [
{
"type": "field",
"inboundTag": [
"metrics_in"
],
"outboundTag": "metrics_out"
}
]
}
在基础配置中增加 metrics
"metrics": {
"tag": "metrics_out"
}
使用方法
pprof
Access http://127.0.0.1:11111/debug/pprof/ or use go tool pprof to start profiling or inspect running goroutines.
expvars
Access http://127.0.0.1:11111/debug/vars
Variables exported include:
statsincludes statistics about inbounds, outbounds and usersobservatoryincludes observatory results
for example with luci-app-xray you are likely to get a result like this (standard expvar things like cmdline and memstats are omitted)

To get a better view of these numbers, Netdata (with python.d plugin) is a great option:
- Edit related configuration file (
sudo /etc/netdata/edit-config python.d/go_expvar.conf) - Take the following configuration file as an example:

Maybe reusing the empty object stats in config file is better than adding metrics here?
Edit: removed prometheus related things and added usage about expvars
