Was this an alert generated by prometheus' alertmanager, or an alert generated by grafana's alerting system?
You said alert was resolved "in 5 seconds" which sounds dubious. Maybe you have some extremely low interval configured for your alerting rules in prometheus? Nonetheless, the history is all in prometheus (at least for the TSDB retention period - default 15 days). You need to work out what expression generated the alert, and use PromQL to explore the data in prometheus. That's all we can say, unless you show the content of the alert itself *and* the rule which you believe generated the alert *and* the data which backs up your assertion that there was no triggering data in that period. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
