Metrics ​

Metrics provide key data states and changes in deployments over a period of time. You can view them on the deployment details page by clicking on Metrics in the left navigation menu.

Serverless Metrics ​

The Metrics page for serverless deployment provides 5 types of metrics: sessions, subscriptions, messages, packets, and dropped messages. You can view the corresponding graphical charts for each type of metric and detailed information at a specific point in time.

Sessions ​

The Sessions chart displays the number of clients connected to the deployment within the selected time period. The number of sessions also includes offline clients that have enabled persistent sessions. Persistent sessions refer to sessions that remain active and store offline messages even when the client disconnects until the session times out and is cleared.

Subscriptions ​

The Subscriptions chart displays the total number of subscriptions within the selected time period.

Messages ​

The Messages chart displays the number of messages received and sent by the deployment within the selected time period.

• Inbound messages are the messages received from the device or application.
• Outbound messages are messages sent to the device or application.

Packets ​

The Packets chart shows the traffic of the messages received and sent by the deployment during the selected time period, including the following three types of data:

• Total packets: Total traffic of packets received and sent.
• Sent packets: The traffic of packets sent to the device or application.
• Recieved packets: The traffic of packets recieved from the device or application.

Dropped Messages ​

The Dropped Message chart shows the messages that are discarded during the sending phase within the selected time period. The reasons for messages being dropped can be that messages are too large in size, the message queue is full, or the message expires.

Dedicated / BYOC Metrics ​

The Metrics page for Dedicated and BYOC deployment provides 5 types of metrics: sessions, subscriptions, messages, packets, and dropped messages. You can view graphical charts corresponding to each type of metric and detailed information at a specific time. For some metrics, the corresponding metrics in the API are indicated. If you need to learn and view more metrics, you can retrieve more metrics through the API - Metrics.

Sessions ​

The Sessions chart displays the number of concurrent sessions within a selected time period. The number of sessions includes offline clients that have enabled persistent sessions. The chart provides 3 metrics:

Subscriptions ​

The Subscriptions chart provides 3 metrics to display the subscription status within the selected time period.

Messages ​

The Messages chart provides 3 metrics, showing the number of messages received and sent by the deployment during the selected time period, and the messages with no subscribers.

Packets ​

The Packets chart provides 2 metrics, showing the traffic of messages received and sent by the deployment during the selected time period.

Dropped Messages ​

The Dropped Messages chart shows the number of messages that are dropped during delivery due to either expiration or the message queue reaching its capacity within the selected time period.
