Availability Graph Widget displays "No Data File" message

Availability Graph Widget displays “No Data File” message

The rrd command looks for a “availability-.rrd” file that does not exist. Here is the output:

RRDTool Output

ERROR: opening '/opt/librenms/rrd/pt-cb-swf02/availability-.rrd': No such file or directory

On Devices, I can see the Availability correctly.
