Hi,

                I am new to observium. 

I have a strange issue ;for only one of the devices in the network. 

The port*.rrd files for this device is not getting generated in the /opt/observium/rrd path. The other rrd files are being generated for this device. 

Because of which the dashboard does not show any graphs for the ports on this device. 

I ran the poller script manually for this particular device and the ports*.rrd files got generated but after I exported the files to an XML I could see all values as NaN.

             Also these port rrd files are not getting updated at regular intervals like the other rrd files for the same device. 

How do I debug this? Help would be appreciated.  

Regards,

Manish
