I am having some problems with viewing graphs.

I can see my overall graph like this:

But when I click into it for more detail I get:

Not sure if it is a rights issue, or something else. I am not a Linux guru. Here is a copy of my validate.php output.

Component Version
LibreNMS 1.58.1-4-g175516f5f
DB Schema 2019_04_22_220000_update_route_table (147)
PHP 7.2.24-1+0~20191026.31+debian10~1.gbpbbacde
MySQL 10.3.18-MariaDB-0+deb10u1
RRDTool 1.7.1


[OK] Composer Version: 1.9.1
[OK] Dependencies up-to-date.
[OK] Database connection successful
[OK] Database schema correct
[FAIL] The poller (LibreNMS) has not completed within the last 5 minutes, check the cron job.

I noticed the poller Fail. I am not sure if this is related or not, I was going to open a separate thread for this, once I got my current issue dealt with.

Thanks in advance for any assistance.
