All graphs empty

[adma]

Hi,

every graph on my Cacti is empty.
When I go to the log i can see that rrd update is getting unknown values

/usr/bin/rrdtool update /var/www/html/cacti/rra/test_hdd_used_34.rrd --template hdd_total:hdd_used 1548081061:U:U

and that is for all graphs except ones that are auto created for Local machine. If i run real-time i can see values are fetched. Also, in log i can find results of executed scripts and they are correct.

Ubuntu timezone is set to Europe/Copenhagen and the same is in php.ini, for mariadb utc+1

Can someone help me solve this issue

I would check permissions for spine (if you are using it), and permissions for rra folder
and log folder (s/b writeable by cacti).
Check your crontab settings, and check the poller settings.

Good Luck,

Thanks for your reply.

in crontab poller.php is run every minute by root
owner of the whole cacti folder is www-data.

It worked for 7 days. Now it only works for graphs that are created for localhost.

Seems like this was the issue:

DQ[Net-SNMP - Get Device I/O] RECACHE ASSERT FAILED '2230477<0:6:12:41.60

After verbos these queries, graphs started working again.
