What solution to use to collect statistics in asterisk?

Question

Asterisk

Actually, I'm interested in viewing the Asterisk call log with the construction of beautiful graphs for guidance.
There are no special tasks such as billing or control over operators yet.
Interested in ease of installation and beauty of reports :)
The solution should be free (or free "for small installations") for Asterisk (not FreePBX)!
What do you advise?

Answer 1

There is already a finished Viewer

Answer 2

I once used Asterisk CDR Viewer . There is an article on habré on how to finish it. But in the end, I had to write my own reporting system with a separate database, where data from the default Asterisk database was replicated.
