NimbostratusSCOM Pool or Pool Member Performance Indicators
From looking through the documentation, I know that there are a set of statistics available through the F5 management pack for pools or pool members:
Current Connections
Maximum ...
So the way we calculate this avg/sec is by keeping track of the previous value received from the Big-IP as well as the timestamp. When the next value comes in, we take the difference of the 2 values and divide it by the amount of time that passed. For instance:
Received Bytes Out: 5302 @ 10:12:56
Received Bytes Out: 5518 @ 10:13:23
Works out as: 216 bytes / 27 seconds = 8bytes/sec which can be read as "the average increase in bytes out is 8 bytes per second".
That negative value you are seeing is actually a product bug that I was able to find today based on your logs. It looks like some packets are received in the wrong order, which creates a negative time span, which unchecked, then creates a negative average value. I've fixed the issue and it will be in the September release.
