Metrics report usage of your Hub and Devices.
For each metric you can choose among 5 time scales:
1 . Last 60 min: values from 1 hour ago to the last minute, aggregated per minute,
2 . Last 24 hours: values from 24 hours ago to last hour, aggregated per hour,
3 . Last 7 days: values from 7 days ago to last day quarter, aggregated per 6 hour,
4 . Last 30 days: values from 30 days ago to yesterday, aggregated per day,
5 . Last 365 days: values from 365 days ago to last 30 days, aggregated per 30 days
Any kind of MQTT packet (CONNECT, PUBLISH, SUBSCRIBE, PING, …) is counted as 1 message. The same message published to several devices counts as many recipients devices.
Device1 connects & publish a message with qos1 Device1 CONNECT -> Hub <- CONNACK PUBLISH -> <- PUBACK This counts as 4 messages for Device1. This message is distributed to Device2 and Device3 (with Qos1) Hub PUBLISH -> Device2 <- PUBACK PUBLISH -> Device3 <- PUBACK This counts as 4 messages. So in total 8 messages transited through the Hub.
A device is flagged as connected as soon as the Hub receives a valid CONNECT packet and accepts it. It is flagged disconnected after its connection has been closed. It is considered active during a period interval if it was connected at least once during that interval.
Device active state is represented with a green positive bar, while an inactive state will be represented by a red negative bar.
Device1 connects at 9:10am, disconnects at 9:11am. - In **Last 60 min** period, it will be counted as active for *9:10am* and *9:11am* bars. - In **Last 24 hours** period, it will be counted as active for *9:00am* bar. Device2 connects at 9:11am, disconnects at 10:31am. - In **Last 60 min** period, it will be counted as active for *9:11am* to *10:31am* bars. - In **Last 24 hours** period, it will be counted as active for *9:00am* and *10:00am* bars.
