Hi All
I have set up InfluxDB and checked the historoical chart of Interface and Host
details.
I have 4 questions.
1) I specified InfluxDB Storage as "2".
In that case, the data shown in host.details (except for Flows) are the
cumulative data of the period spcified at InfluxDB Storage?
Or InfluxDB setting does not affect those menues?
No, this is not affected. This data is cumulative since the start of the
ntopng service.
2)I specified InfluxDB Storage as "2", however it seems older data remains in
the influxDB.
I assumed that historical data older than 2 days should be deleted from
influxDB.
I experience the same behaviour. It seems like the cleanup occurs in 24
hours:

3)When I select certain protocol (e.g. SSH) on the "Timeseries" and click the
graph to zoom.
It shows "No data found" even though I clicked on the graph where "byte_rcvd" and
"byte_sent" exist.
Does it mean the data specified date does not exist in the influxDB?
Please update to the new 3.7 version of ntopng which has many fixes. 3.5
is not supported anymore.
4)When I go to historical chart of host, I see the error
"HTTP/1.1 500 Internal server error Content-Type:text/html Connection: Close ! scriipt
"/usr/share/ntopng/scripts/lua/host_details.lua" returned an error:
/usr/share/ntopng/scripts/lua/modules/grph_utils.lua:579:
Atempt to index local 'stat' (a nil value) My ntopng version is v3.5.181112
Please see the answer above.

Emanuele
I attach the screenshot of Preference and error message.
Best Regards,
Ebihara
