When viewing the Statistics :: Analytics :: TCP :: RTT, then selecting (in the table below the graph), View By: "Remote Host IP Address", the values presented RTT Avg (ms) may be incorrect (they could even be larger than the RTT Max column). As values are aggregated through the data tables, the reported rtt average value becomes larger and larger.


The values reported in the RTT Avg column when viewing by Remote Host IP Address may be incorrect.


AVR is provisioned, and a tcp-analytics profile is attached to a virtual server.



Fix Information

The rtt_count, rtt_max, rtt_avg, rtt_sum metrics after day aggregation and week aggregations are now correct in the day, week, month reports. The rtt_sum is now aggregated with correct value (exceed max int), as expected.
