How are sessions counted in the paid plan?

How Sessions are Counted:

In the HiveMQ Cloud, sessions align with concurrent MQTT client sessions. Each active MQTT connection equals one session. Each persistent session, active or inactive, also counts as a session. If a device establishes multiple sessions simultaneously (using a different Client ID for each session), each is considered a separate connection. Counts reset to zero monthly.

Example:

1. Multiple short-time connections within an hour:

   • 37 devices connecting every hour for a few minutes count as 37 connections.

2. Combination of persistent and non-persistent sessions:

   • 10 devices with persistent sessions (cleanSession flag set to false) + 27 devices connecting hourly = 37 total connections.

Displaying Session Count:

The "MQTT Client Sessions" count at console.hivemq.cloud reflects the max session count reached in the current month, resetting monthly. It doesn't show active connections but the max count reached.
