[smokeping-users] Problem using Smokeping RRD in PHPWeathermap

Fri Jun 27 17:01:53 CEST 2014

I thought of another possibility.  Your rrd configuration may somehow be be non-standard so AVERAGE has no data to fetch.

Try `/usr/local/bin/rrdtool fetch <file> AVERAGE --start now-800 --end now`
and `/usr/local/bin/rrdtool fetch <file> MAX --start now-800 --end now`
and `/usr/local/bin/rrdtool fetch <file> MIN --start now-800 --end now`

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 at 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.

Addendum...

BTW, here is my phpweathermap node config:

NODE node09727
LABEL Latency {node:this:bandwidth_in:%d} ms / Loss 
{node:this:bandwidth_out:%d}%
TARGET 
gauge:/www/phpweathermap/htdocs/fs_smokeping/Network/switches/sw-mm2sqpk.rrd:median:loss
USESCALE pingloss in
POSITION 153 76

Thank you,

td
