If the responsiveness of one storage node degrades, you can only see that some of your requests are bad, either as high latency or error status codes. You do not know exactly why or where that request tried to go. Maybe the container server in question was on a good node but the object server was on a different, poorly-performing node."

There is no way to increment a counter by more than one or send timing data to StatsD based on the log line content. The tool could be extended to handle more metrics for each line and data extraction, including timing data. But a coupling would still exist between the log textual format and the log parsing regexes, which would themselves be more complex to support multiple matches for each line and data extraction. Also, log processing introduces a delay between the triggering event and sending the data to StatsD. It would be preferable to increment error counters where they occur and send timing data as soon as it is known to avoid coupling between a log string and a parsing regex and prevent a time delay between events and sending data to StatsD."

To use this extension, create a queue and specify the min/max bandwidth rates (kbps) and optionally set the QoS Marking and DSCP value (if your network fabric uses these values to make forwarding decisions). Once created, you can associate a queue with a network. Then, when ports are created on that network they are automatically created and associated with the specific queue size that was associated with the network. Because one size queue for a every port on a network might not be optimal, a scaling factor from the nova flavor 'rxtx_factor' is passed in from Compute when creating the port to scale the queue."
