Hi All,
I want to ask is there any history table in camunda that saving start date time and end date time of each activity/task completed. I use community version right now, is it possible to get that data if I use community version?and if yes in which table or some configuration that must I use to get the data?
Thanks
Hey!
Check out this docu for Camunda’s historic database Schema: Database Schema | docs.camunda.org
Back in the days I exported these kind of metrics via Prometheus to Grafana in order to visualise them. You can find some pretty nice examples by @StephenOTT!
Besides you could of course query the historic database or use the rest api. 
Let me know if that answers your question!
Best,
Thomas
The Prometheus specific app is replaced with: GitHub - StephenOTT/Camunda-Monitoring: Monitor anything you can query in a Camunda BPM engine. Monitor KPIs, metrics, and any business performance
which implements micrometer so you can use any number of reporting engines: Micrometer Application Monitoring see #3
