We're collecting EUR/USD prices every minute on Prometheus and setting up various alerts, such as percentage changes over the last 10 minutes and the last hour.
The data flow works seamlessly; however, I am unable to set a time-to-live (TTL) on the alerts. For instance, an alert triggered a month ago remains active in Prometheus. I want to set a TTL on alerts, similar to Redis keys, so they are automatically deleted after the TTL expires. As far as I can tell, this isn't possible with Prometheus, resulting in many outdated alerts still being active.
Is Prometheus the right tool for this scenario? Can I delete alerts programmatically, assuming there is no TTL feature?
exprremains valid (if it didn't the alert would disappear) and they're being overwritten.
