Doc Type: Known Issue
Doc Text:
The logging queue that buffers excess security group log entries sometimes stops accepting entries before the specified limit is reached. As a workaround, you can set the queue length higher than the number of entries you want it to hold. + You can set the maximum number of log entries per second with the parameter `NeutronOVNLoggingRateLimit`. If the log entry creation exceeds that rate, the excess is buffered in a queue up to the number of log entries that you specify in `NeutronOVNLoggingBurstLimit`. + The issue is especially evident in the first second of a burst. In longer bursts, such as 60 seconds, the rate limit is more influential and compensates for burst limit inaccuracy. Thus, the issue has the greatest proportional effect in short bursts. + Workaround: Set `NeutronOVNLoggingBurstLimit` at a higher value than the target value. Observe and adjust as needed.
