Generated rrd file after adding a new deivce is owned by root

Help
1

From some time to now when i add a new device to librenms the generated rrd file to store its graphs is owned by root instead of librenms user.

I have to manually change the ownership of the rrd file to librenms to start graphing. What am i doing wrong? Any advice?

The /opt/librenms folder is owned by librenms:

drwxr-xr-x 31 librenms librenms 4096 Jun 12 12:55 librenms

And all previously generated rrd files inside and the rrd folder also are owned by librenms user

drwxrwxr-x+ 1459 librenms librenms 126976 Jun 12 12:40 rrd

Hi,

How are you adding the device?

4

From the top menu

Devices -> + Add Device

Sorry, newly created by the rrd are owned by nginx:apache instead of librenms:librenms

drwxrwxr-x+ 2 librenms librenms 12288 Jul 10 10:00 ssw00010003.xxx
drwxrwxr-x+ 2 librenms librenms 4096 Jul 10 11:55 swc00010002.xxx

@rokkhan you wouldn’t happen to be going into the Capture screen and be clicking poll would you?
