Hi everyone,
Since an update, (but i don’t know which), RRD files are not longer created in /opt/librenms/rrd/ folder and graph are in "Error Drawing Graph’ on the web UI.
I have suspected a right issue on the rrd folder, but evrything seems to be ok.
This folder is owned by librenms user and group.
The http user is also in librenms group.
This problem concern only devices added recently. All the old devices are updated correctly.
On the rrd/ folder, a folder is created with the device name, but nothing is created inside.
If I run a : ./poller.php -h cbv-pa7-a9k1-pe-01 -r -f -d
In the output I see lines like

I don’t know how understand the RRD Disabled line.
It say : create /opt/librenms/rrd/cisco-a9k1/poller-perf.rrd but nothing is created.
If I take the RRD file of an other (similar) device, and copy it to empty folder, the corresponding graph works.
Thank a lot for your advices
