Hello! We are self hosting signoz. But all our alerts show up with localhost:8080 in slack. We’ve set the alert manager base url with no luck.
Any ideas ?
Are you referencing “SIGNOZ_ALERTMANAGER_SIGNOZ_EXTERNAL__URL”?
We’re using the helm chat and seeing the value we think is related “signoz_alertmanager_signoz_external_url” (it doesn’t add the double underscore?)
I also looked at the GitHub repo and can’t really see that envvar used anywhere?
We’re on the last signoz

Please use this:
signoz_alertmanager_signoz_external_url
( without the double underscore, as mentioned in the helm chart)

Yeah we’ve set that and still results in localhost :( , is this dependent on the version of signoz we’re on?
