Enterprise Manager shows different statistics numbers than BIG-IP appliance

[update] Talked to F5 support in the mean time. They've confirmed the issue (PVA traffic not contributing to the collected Throughput Statistics). They have divided this issue into two - one is the missing PVA traffic statistics in the Global Traffic statistics (introduced on the LTM since 11.4.0). The other is Enterprise Manager not collecting and including PVA statistics in it's statistics. Resolution of these issues should be made in the next major TMOS release. I'm awaiting an Engineering Hotfix based on LTM 11.5.3-HF2 and hope to give a positive feedback once installed.
