FlowSphera 1.16.2 release notes

Capacity: «Not enough memory» on a firewall with many interfaces: the interfaces' own counters (SNMP every minute) were turned into rates from every read of the whole period at each opening of the page — a FortiGate with hundreds of interfaces has ~21 million reads in a month, and the page ran out of memory before it had read them. The rates are now made once, in 5-minute steps, as the counters come in, and Capacity reads those: measured with 500 interfaces over 30 days, 13 s → under 2 s and a quarter of the memory. After the upgrade the history of the counters is gone through once (seconds to a minute); until then the page works as before. The numbers are the same, exactly.
IP reputation: ThreatFox needs a key now: abuse.ch stopped giving the ThreatFox list without a (free) Auth-Key — the download failed with «410 Gone» everywhere. Settings → Events → IP reputation has a Key (Auth-Key) field for every list: ThreatFox shows «needs a key» with a link to get one free, then downloads through its API (the addresses of the last 7 days). Any other list can be given a key the same way if its publisher starts asking for one. Keys stay on the server (a file only FlowTrack reads); the page never shows them back, an empty field keeps the saved one, and a wrong key is said plainly.
The web service no longer fills its log with a traceback each time a browser closes a page while it is loading.
