In one of the recent updates (appears to be midnight 30/7) graphs have stopped having data show up. They’re still progressing, but have flat lines at 0 in them.

the poller log has a lot of entries like:
/opt/librenms/poller.php 72 2019-08-07 10:03:09 - 1 devices polled in 3.005 secs
which seems like it’s working normally.
The disk is not full (6Gb free)
Where should I start looking? Everything seems to work, except the bit where the graphs update with information from the pollers.
