Label is hard as each label blows up the storage requirements in prometheus. I am not sure if I am logging it though. Have you checked there?

@till we just have an information about if the resource blacklisted or not. That’s it.

@zentavr maybe logging the response? Would you be able to help with a PR?

@till I’m not so good with the Golang, but I can try that.

@zentavr I have to rebase my PR, but potentially it is already fixed (or at least I tried to):

dnsbl_exporter/pkg/rbl/rbl.go

Lines 82 to 104 in 6ba677d

 if reason == nil { 

 logger.Error("error getting (first) reason: %s", strings.Join(res, ", ")) 

 result.Error = true 

 result.ErrorType = fmt.Errorf("error getting the (first) reason: %s", strings.Join(res, ", ")) 

 c <- result 

 return 

 } 

 // fetch (potential) reason 

 txt, err := r.util.GetTxtRecords(godnsbl.Reverse(reason) + "." + result.Rbl) 

 if err != nil { 

 logger.Error("error occurred fetching TXT record", slog.String("msg", err.Error())) 

 result.Error = true 

 result.ErrorType = err 

 c <- result 

 return 

 } 

 if len(txt) > 0 { 

 result.Text = strings.Join(txt, ", ") 

 } 

 c <- result

Do you have an example of a listed host that I can use?

So, do you want to produce an error string and fetch it with the tool like promtail (then Loki -> Grafana), correct?--Thanks, Andrii Miroshnychenko ***@***.*** серп. 2023 р. о 14:54 Till! ***@***.***> пише: @zentavr I have to rebase my PR, but potentially it is already fixed (or at least I tried to): https://github.com/Luzilla/dnsbl_exporter/blob/6ba677d467c26e31b87e1a794220975d780ecc1d/pkg/rbl/rbl.go#L82-L104 Do you have an example of a listed host that I can use? —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you were mentioned.Message ID: ***@***.***>

@zentavr yeah, I guess. A logline, because the /metrics endpoint doesn't really suite itself to show errors.
