Getting total bandwidth currently utilized in an iRule

not sure if this is useful.

since 11.1.0, virtual server or pool AVR statistics can be obtained using ISTATS::get command in irule (e.g. ISTATS::get "VIP virtual-server-name counter type). anyway, it is not realtime statistics because statistics needs at least about 10 seconds to be updated (i.e. it is previous update interval statistics). to see all the types, you can run "istats dump" in bash.

e.g.

root@(B3900-R67-S12)(cfg-sync Standalone)(Active)(/Common)(tmos) list ltm virtual bar
ltm virtual bar {
    destination 100.100.100.101:80

    mask 255.255.255.255
    pool foo
    profiles {
        http { }
        myanalytics { }
        tcp { }
    }
    rules {
        myrule
    }
    source 0.0.0.0/0
    source-address-translation {
        type automap
    }
    vs-index 3
}
