Weathermap not refreshing

[jagmeetbhinder]

Hello,

I have strange problem with my Weathermaps graphs are intermittently stop working and then starts again. During issues i have captured logs below. I have also attached the configuration file.


=======================================================================================================================

Another thing I noticed today that whenever maps are not refreshing i need to click the map and then click on any link which then redirect me to cacti map url. After next pooling cycle everything seems to be normal. Works for sometime and then stop again.

Thanks

Update:

I checked through debug logs that weathermap is pulling last 16 values from rrd file and my last 16 values are showing nan.

@cacti rra]$ /usr/bin/rrdtool fetch /var/www/html/rra/tr01crsw31_traffic_in_5754.rrd AVERAGE
traffic_in traffic_out
