Performance Graph : Throughput

[surajsah]

Hi Team, What is the meaning of "Service" in the throughput graph. I can see the "Bit In" and "Bit out" are overlapping but the "Service" line peaks far higher than IN and Out line during the midnight time. What does this mean ?

Thanks much!

Can you provide the graph snapshot and code version that you are using ?

I know this post is old, but I was looking for the same thing and found this thread. After searching a little further I found this article: K50309321.

Service: The larger of two values when combining either Client Bits In and Server Bits Out or Client Bits Out and Server Bits In

Cheers!

Usually the graphs for "in", "out" and "service" overlap more or less as long as the in/out volume is similar.

Recently we noticed high spikes for "service" traffic on the active unit in a device group where mirroring is enabled for some virtual servers (in PerformanceL4 mode). At the same time we noticed high CPU and problems with some applications handled by the BIG-IP.

So perhaps the "service" traffic includes as well the mirrored traffic. I´m under the impression, that the mirroring failed somehow and caused the CPU and throughput (service) spikes.
