| :ref:`dolphin <cce_10_0371>` | dolphin is a pod network monitoring add-on, which, in the current version, can be used to collect statistics about public network traffic of Kata containers in CCE Turbo clusters and common containers that use containerd as the runtime. |
| | |
| | This add-on collects how many IPv4 packets and bytes are received and sent (including those sent to the public network). PodSelectors can be used to select monitoring backends to support multiple monitoring tasks and optional monitoring metrics. You can also obtain label information of pods. The monitoring information has been adapted to the Prometheus format. You can call the Prometheus API to view monitoring data. |
