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 (
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.
To view hub metrics, click on Metrics tab of your Hub.
The metrics of the Hub are visualized as graph:
To display metrics, in the Devices tab of your Hub:
if you click on the device name, it will open the Device Information view, including Device metrics,
if you click anywhere else on the device line, metrics appears in the expanded content (NOTE: in that case you only have the last 24 hours period).
