have you ever tried to set statistics interval to something like a week?<br>

I assume you mean sample_retention_policies (i.e. how long we hold stats for) rather than collect_statistics_interval (i.e. how frequently the broker should emit stats for the management plugin to collect).<br>
<br>
No I haven't, although you should be fine as long as you reduce the resolution for data that's held for longer. Or put up with increased memory use.<br>
