The Phoenix documentation I have ingested does not mention how to customize or specify a threshold for the latency column in the Phoenix Dashboard that would change its color (such as turning red) based on a project-specific latency value. If you need this feature for visual alerting or monitoring, please clarify if you are looking for a global setting, per-project configuration, or a UI-based toggle, as this detail could help in identifying possible workarounds or feature requests. If this doesn't help, please reach out to the Phoenix support team for further assistance.
