Ce sont des metrics ressource et traffic reseau plutot que des metrics fonctionnels

2. Database
- Coturn dispose d'une BDD (que nous n'avons pas active sur notre infra de prod)
- Cependant, rien a en tirer d'apres le [schema de la BDD](https://github.com/coturn/coturn/blob/master/turndb/schema.sql)

3. Logs
- En analysant les logs pour une conversation sur les services coturn, on s'apercoit que nous avons des informations plutot oriente reseau que fonctionnelles.
- Une tentative de calcul d'appel a ete effectue [ici](https://github.com/tchapgouv/tchap-infra/issues/2408#issuecomment-2018159910) mais ceci est bien trop approximatif

Je ferme cette issue car nous n'avons pas d'information exploitable avec ce que l'on a actuellement pour repondre a ce besoin

=> Une solution Posthog serait plus appropriee : https://github.com/tchapgouv/tchap-stats/issues/71
