LibreNMS can't show the device graph

Hi Gent,
I have new installed LibreNMS server, After add the new device and waiting for 30min , I dound the LibreNMS can report the device property but can’t show the graph.
Anyone have solution please recommend.

Below is my validate.php

And I have noticed no graph create in rrd folder.

root@clanms02:/opt/librenms/rrd

ls -l
total 4
drwxrwx—+ 2 librenms librenms 4096 Mar 6 12:15 10.203.4.1
root@clanms02:/opt/librenms/rrd
ls -l 10.203.4.1
total 0

And my WebUI show as below.

OKay… I’ve fixed it by update the CentOS patch. But don’t know what the relate package is.

Nice!

If you want to check recently installed packages you could post a recent output of

rpm -qa --last

Maybe it will help someone else too :slight_smile:

Also you shouldn’t ignore things in your validate
