> > > Hi iamliangdi, thx for opening this issue. It is a good point that ds should have some alert mechanism in case `alert-server` fails itself. May I ask how do u want to improve the availability of `alert-server`?

Just for double-check, if alert-server fails for some reason and restarted later, during the failure, will alerts still get stored in db and sent as soon as alert-server restarts? Yes. The alert service consumes very few resources. So i recommand the following two ways to ensure production stability: 1. Deploy alert server in a single instance. 2. Using systemd or supervisor to manage the process of ```alert-server```. @iamliangdi -- This is an automated message from the Apache Git Service.
