Grafana 8 Unified Alerts Error Unsupported Path

[arnoldyahad]

Hey guys,
We are using VMDB 1.62.0, and recently we updated our grafana to 8.0.6
we opted-in the new unified alerts system: link here and here

Now we see that in the alerts menu in grafana there is this message:

To Reproduce
Use VMDB as a prometheus datasource in Grafana(version 8.0.6), enable the new unified alerting system:
here through your grafana configuration(usually /etc/grafana/grafana.ini)

Expected behavior
Fixing the endpoint to be valid for Grafana 8.

Logs
Logs from our kibana show that this query is being performed multiple times in a second:

It fills up the warning logs, and its also an unnecesary load on vmselect.

It seems that there is no rule-related interface implemented in VictoriaMetric

just placeholder

thanks for replying @jinlongwang

when using the endpoint you provided - it works, but its not the endpoint that grafana is querying:

# This is what grafana tries to query: 
curl https://my-vmselect/select/0/prometheus/rules
remoteAddr: "xx.xx.xx.xx:54348", X-Forwarded-For: "xx.xx.xx.xx"; unsupported path requested: "/select/0/prometheus/rules"

# This is what is implemented to work 
 curl https://my-vmselect/select/0/prometheus/api/v1/rules
{"status":"success","data":{"groups":[]}}%

so basically the change needed here is relatively small - just to open another case of prometheus/rules which is a copy of prometheus/api/v1/rules

according to the error msg, it can be found it is the return of vm-auth, maybe you need to have a look of auth.config.

Thanks for the reply @Zhouhenry but it doesnt work even locally:

/ # curl localhost:8481/select/0/prometheus/api/v1/rules
{"status":"success","data":{"groups":[]}}/ #
/ #
/ # curl localhost:8481/select/0/prometheus/rules
remoteAddr: "127.0.0.1:55908"; unsupported path requested: "/select/0/prometheus/rules"
/ #

It just needs to be on a different endpoint to support grafana 8 unified alerting.

VictoriaMetrics should return dummy response for /rules page starting from v1.64.0.
