ntopng/scripts/lua/admin/prefs.lua
emanuele-f 20ef1a4ebc Fix ts_utils.listSeries in redis.lua being performed on every page load 
This was caused by probe.getTimeseriesMenu being called at every page load by the timeseries
code to load the schemas. probe.loadSchemas is now called instead.

-- the only other option is 300 seconds (5 minutes) and there's
-- no need to use timeseries rings
if driver == "influxdb" and high_res_secs <= 60 then
new_slots = 60 / high_res_secs
new_steps = 60 / new_slots / 5 -- TODO: remove this hardcoded 5
-- important: add one extra slots to give "buffer" time to the writer
new_slots = new_slots + 1
end
-- When high resolution timeseries are enabled, the ntopng C core creates
-- timeseries rings with diffent slots. Each slot holds a snapshot of the
-- host/interface timeseries in a given time interval. For example, if 10s
-- resolution is choose, each slot holds a snapshot representing an interval
-- of 10s. Periodically (in NetworkInterface::periodicStatsUpdate) the slots
-- are polulated and then in minute.lua they are read and exported.
--
-- This Redis preferences tell the C core how to configure the ring:
-- - ntopng.prefs.ts_write_slots: the number of slots to allocate in the ring
-- - ntopng.prefs.ts_write_steps: how many ticks of NetworkInterface::periodicStatsUpdate
-- are necessary to fill a slot.
--
-- For the example above of 10s resolution:
-- - ntopng.prefs.ts_write_slots = 60 / 10 = 6 slots, + 1 extra slot as buffer (see above) = 7
-- - ntopng.prefs.ts_write_steps = 60 / 6 slots = 10s / 5 (5s is the periodicStatsUpdate interval) = 2
--
-- See TimseriesRing.cpp for more details.
