Produits Entr'ouvert » Publik

Il faut renseigner quelques variables pour pouvoir profiter de

la configuration automatique de Matomo :

- l'url d'un serveur matomo

- le login et mot de passe d'un administrateur du serveur matomo

Par exemple chez Entr'ouvert :

/var/lib/hobo/tenants/hobo.dev.publik.love/settings.json:

{

  "MATOMO_FEED": {

    "URL": "https://matomo-test.entrouvert.org"

    "TOKEN_AUTH": "xxx"

}
