This gauge reports the lowest amount of available memory observed during the sampled interval on the fabric-interconnect switch's onboard OS, as recorded in one archived historical sample of the fabric-interconnect switch's CPU-load and memory-usage statistics. An administrator watching for a switch supervisor running low on memory checks this memAvailableMin figure to catch a declining trend before the switch begins struggling to run its own management processes. For example, a steadily shrinking memAvailableMin figure across successive samples would prompt an operator to investigate a possible memory leak on the switch supervisor before it becomes critical.
