phpweathermap is running rrdtool fetch to get the data. From your debug, it is retreiving the nan's:
> /usr/local/bin/rrdtool fetch > /www/phpweathermap/htdocs/fs_smokeping/Network/switches/sw-mm2sqpk.rrd > AVERAGE --start now-800 --end now > DEBUG: [wmrrd_read_from_real_rrdtool@WeatherMapDataSource_rrd.php:382] > configs/smokeping_test.conf: > 1403873700: nan nan nan nan nan nan nan > nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan It must not be reading the same rrd file that smokeping is using. Check the datadir configuration option in your smokeping config file to see if the path is the same. -Russell Dwarshuis ----- Original Message ----- From: "Tony DeMatteis" <to...@commspeed.net> To: smokeping-users@lists.oetiker.ch Sent: Friday, June 27, 2014 9:24:38 AM Subject: Re: [smokeping-users] Problem using Smokeping RRD in PHPWeathermap Addendum...
