Analytics module (Advanced Visibility and reporing) historical data

I can't find any data on how data is stored and collected historically or how it is configured via the GUI. I suspect what you're seeing is the intended behaviour but I'd suggest you talk to F5 support and confirm this. If you do, please post back.

btw, I found these bigdb entries but I wouldn't mess with them without F5 support confirming it's safe;

sys db avr.distributedreporting.maxtiersize {
    value "4"
}
sys db avr.stats.distributedfactor {
    value "2"
}
sys db avr.stats.internal.maxentitiespertable {
    value "20000"
}
sys db avr.trafficcapture.external.syslogseverity {
    value "info"
}
sys db avr.trafficcapture.internal.enabled {
    value "true"
}
sys db avr.trafficcapture.internal.maxentriesperfile {
    value "10"
}
sys db avr.trafficcapture.internal.maxtransactions {
    value "1000"
}
