Usage of WebUI behind reverse proxy (subtree / baseurl)

[falkheiland]

I am using snmp_exporter in a docker container behind traefik. where, in prometheus and alertmanager, i can specifiy

--web.external-url=https://<baseurl>/<subtree>

this parameter does not exist in snmp_exporter.
In the compose file i can have traefik labels like:

- "traefik.http.routers.snmp-exporter-secure.rule=Host(`<baseurl>`) && PathPrefix(`/<subtree>/`)"
- "traefik.http.middlewares.snmp-exporter-secure.chain.middlewares=secHeaders@file,default-auth@file,strip-prefix"
- "traefik.http.middlewares.strip-prefix.stripprefix.prefixes=/snmp-exporter"

which allow me to access https://<baseurl>/<subtree>/config + https://<baseurl>/<subtree>/snmp but in the WebUI the links are still the same: https://<baseurl>/config.

i would like to have the web.external-url parameter in place or another viable soulution for that scenario.

This seems reasonable to me.

Hello,
Like blackbox exporter, can you add --web.external-url ?
This would allow you to use snmp exporter behind a reverse prox?

Thanks.
