As shown above, some metrics do not display the container name. In place of the name only the container ID is displayed.

Inspect the code that generates the dockerwall_dropped_packets metric and assigns its container labels. Reproduce the reported output with a dropped-packets metric, then verify that the name label shows the container name rather than its ID while retaining the ID label separately.
