Examples:

Possible Solution

No idea!

Steps to Reproduce (for Bugs)

Paramétrer une tâche Cron (chargement plus rapide des rapports):

⚠ Warning: Pour des performances optimales et un Matomo rapide, il est vivement recommandé de mettre en place une entré CRON pour archiver automatiquement vos rapports, et de désactiver le déclanchement depuis l'interface depuis les paramètres Matomo. Apprenez-en plus.

Browser and Auto-archiving enabled:

⚠ Warning: It looks like both browser and auto archiving are enabled. Auto archiving last started 9 min 42s ago. If auto archiving is enabled, you should disable browser archiving in "General Settings".

Paramétrer une tâche Cron - Gestion des processus via la ligne de commande:

✔ Ok

Capacités de la base de données:

✔ UTF8mb4 charset ⚠ Warning: LOAD DATA INFILE
L'utilisation de LOAD DATA INFILE va grandement accélérer la vitesse du processus d'archivage de Matomo. Pour le rendre disponible à Matomo, essayez de mettre à jour PHP & MySQL et assurez-vous que votre utilisateur MySQL a les privilèges de FILE.
Si votre serveur Matomo suit des sites à fort trafic (ex. > 100000 pages par mois), nous recommandons d'essayer de corriger ce problème. ✔ CREATE TEMPORARY TABLES ✔ Changing transaction isolation level

Taille maximale des paquets:

⚠ Warning: Il est important de configurer une taille 'max_allowed_packet' dans votre base de données MySQL d'au moins 64MB. 32MB configuré en ce moment.

Connexion SSL forcée:

✔

Géolocalisation:

⚠ Warning: Le fournisseur de localisation par défaut devine le pays d'un visiteur en se basant sur le langage de son navigateur. Ceci n'est pas très précis, nous recommandons donc l'installation et l'utilisation d'une base de données de géolocalisation.

Mettre à jour via HTTPS:

✔

Traceur JavaScript inscriptible ("/matomo.js"):

Heatmap & Session Recording Tracking:

⚠ Warning: Requesting '$MATOMO_URLplugins/HeatmapSessionRecording/configs.php?idsite=1&trackerid=5lX6EM&url=http%3A%2F%2Ftest.test%2F' resulted in an SSL error. Maybe you are using a self signed certificate? Please open the URL manually in a browser to see if the response contains 'Piwik.HeatmapSessionRecording'. If not, you might need to modify your server configuration as this file needs to be accessible via a browser from the Internet or Intranet.
