Enterprise Manager shows different statistics numbers than BIG-IP appliance
Hi all,
I was wondering if somebody could explain me how to compare the throughput stats between F5 EM (3.1.1-HF4) and F5 BIG-IP (11.5.3).
We run monthly capacity reports on the F5 EM and the throughput numbers of July have dropped by 90% (compared to previous reports - May peak = 2141 Mbps, Jun peak = 1672 Mbps, Jul peak = 23 Mbps !). There was no big change on the LTM configuration of the BIG-IP applicance which could explain this. However, we upgraded F5 EM (from 2.3.0 to 3.1.1) and F5 BIG-IP (from 11.2.1 to 11.5.3) end of June and the numbers have changed since then.
I assume there was a change in the way the EM software calculates the data from the BIG-IP. Therefore I tried to compare the current (3hrs, 1day) throughput numbers between EM (Standard Device Profile, 60sec interval) and BIG-IP (Dashboard view). The dashboard view shows peaks of 1100 Mbps. But the current value is much smaller (about 8 to 23 Mbps).
On the EM the current stats (Device Stats rule) of Global: Client/Server: Bits In/Out are showing values between 200 Kbps and 500 Kbps. Even if I add all four metrics I don't get the same value as shown in the BIG-IP dashboard. What did I miss?
How do I align the EM numbers with the BIG-IP numbers (which are in a range we got in the reports before upgrade).
Any hint is much appreciated. cheers
