Examples could be “response time” of a specific action. A possible solution could be receiving events, such as “action started” and “action finished”. Then Grafana could correlate these two events and compute the resulting response time. Is this possible with Grafana?
Definitely possible. Could depend on what data source you’re decide of using.
