See [IOTDB-5819](https://issues.apache.org/jira/browse/IOTDB-5819). In general, the files in /sys/class/net are considered to represent a network card, as shown in the figure below.  However, in some environments, the /sys/class/net folder may also include non-network card files. <img width="810" alt="7ce6a129ea259417455cdda3f662c91" src="https://user-images.githubusercontent.com/37140360/234213515-057e5e7a-9358-4b4b-8d45-8d51372d4adf.png";> NetMetrics uses a Map from the name of a network card to the status of a network card, and NPE occurs when the file name of a non-network card is used to get the status of a network card. To fix this bug, we use a `getOrDefault` method instead of `get` method to avoid NPE. -- This is an automated message from the Apache Git Service.
