looking in the ntopng log I am getting a lot of:
[ts_5min_dump_utils.lua:461] ERROR: [Inside_VPN]Cannot complete local hosts
timeseries dump. Disk slow or too many local hosts?
ERROR: [Outside]Cannot complete local hosts timeseries dump. Disk slow or
too many local hosts?
I'm assuming the host can't keep up. Our local network is defined as a /16
and it looks like we received about 50-60k flows per minute. For reference
