Known Issues

• #3482 The Catalog API requires that cluster name be unique, if you have two services with the same name and version values. Failure to do so will lead to a mismatch in the Sense Dashboard and you will not see one of the services. If the versions are unique then you can use the same name value.
• #761 The proxy requires a route to be configured on the domain/listener in order for observables to be enabled.
• #65 The Grey Matter Control variable GM_CONTROL_STATS_BACKENDS is ineffectual and does not output stats to prometheus.
• #305 Grey Matter control domain object redirects can't perform port rewrites.
