The graph shows the number of concurrent swap requests present in the proxy server. We count the number of requests in the system using 2 msec intervals and calculate the median based on 20 minute grouping. Small 2 msec intervals assure that we count the number of concurrent requests rather than total number of requests per [large] interval. Note that this graph is not a "disk request per second" graph.
We plot the 50th and 75th percentiles. The 50th percentile is the same as median.
This graph is useful in determining the increase in the length of disk queues during peak hours (if any).
