OK |
OK | The topic has no abnormalities |
NotReceived |
ERROR | The topic has not been received yet |
WarnRate |
WARN | The frequency of the topic is dropped |
ErrorRate |
ERROR | The frequency of the topic is significantly dropped |
Timeout |
ERROR | The topic subscription is stopped for a certain time |
