is there an alert for threshold

Yes, Airbyte has the capability to set up alerts based on certain thresholds. For instance, there are discussions about setting up alerts when certain cron jobs have not run within a specified window or when a sync operation exceeds a certain duration. In one of the [Github issues](https://github.com/airbytehq/airbyte/issues/33317), there's a discussion about setting up alerts for when either of the connection support state cron and the definitions updater cron have not run inside a window. The alert system is set up in such a way that it can notify if these crons are not running, but not if they run with errors. In another [Github discussion](https://github.com/airbytehq/airbyte/discussions/34240), a feature request was made to have the option to define a duration threshold for syncs. The user wanted to receive a warning if a sync operation that is expected to take 20 minutes is running for 2 hours. However, please note that the implementation of these alerts might depend on the specific requirements and the configuration of your Airbyte instance.
