I spent days with it and added new field EndCallTime in table Old-call-log and got some results:
Calls logs with long and short time indicator requirement
I have to use Gannt Chart to achieve the long / short call duration.
Pros: achieve objective showing duration length
Cons: Gantt Chart is not ideal since it’s no longer actively updated, so I want another solution if possible
I feel like status history should be used, but it fails to show the length of the call.
Calls logs and system access logs requirement
Using status history and join Calls table with Logs table
Pros: access logs and phone logs are displayed in the same panel
Cons: Status history still doesn’t achieve objective showing duration length
I spent days on this and wonder if these tasks are actually not possible to do in Grafana?
