Non data centre Bitbucket Server instances will log the below at WARN level whenever someone hovers over the clone button in a repository:

The mirroring feature is not available.

When user hovers over the clone button, the frontend makes a request to the /rest/mirroring/latest/repos/$REPO_ID/mirrors REST endpoint.

Stop doing this as it is unnecessary and adds noise to applications logs.

Steps to fix:

• Stop the frontend from making the request on non-DC instances
• The message shouldn't be logged at WARN level

Workaround

One workaround is to set the log level for com.atlassian.bitbucket.internal.mirroring.upstream.DefaultSmartMirroringFeature to ERROR. Note care must be taken to only set this log level to ERROR for this class otherwise important logging could be lost.
