High Speed Logging has historically made adaptive connections to logging pool members -- as many as are required for the necessary logging bandwidth. This can result in a disproportionate number of logs going to a small number of pool members if all of them are not required to support the logging rate.
This can affect disk usage disproportionately on logging pool members and does not support redundant logging.
Anemic high speed logging bandwidth disproportionately writes logs to few logging pool members.
A Distribution drop-down UI item has been added for Remote High Speed Logging destinations. It can take on the following values: -- adaptive: default behavior adding logging server connections as needed. -- balanced: balancing logs between logging servers according to the load-balancing algorithm. --replicated: replicating logs to all logging servers. This provides: 1) a more balanced approach, distributing logs according to the load-balancing criteria. 2) having logs be replicated across all pool members for redundancy.
