bug for 1.2.1 ???

[nationals]

just flush install 1.2.1 with spine on ubuntu 18.04 lts (nginx1.14+php7.2-fpm+mysql5.7).

and add 3 linux server (centos, ubuntu) with snmpd for monitor,

it seems ok. but:

the realtime graphs is all ok.

the normal graphs is empty.

why? or it is just a bug?

[netniV]

usually it'll be either SELinux, AppArmour and/or file/folder permissions.

[nationals]

check file is created and update correctly.

it seems can not be load for display.

[netniV]

check your website user has access to read the data.
