Does the program spit out the raw numbers anywhere? If so, then you can write a script to parse them and feed it to cacti.

Look into a writing a Perl script. Paste a sample of the text file and I'll see what I can do.

Ok, got the script done. Since the vantage software writes the log file every minute, I have the script read the last entry.

Code: Select all

c:\perl vantagepro.pl downld02.txt
tempout:14.8 hitemp:14.8 lowtemp:14.8 outhum:81 dewpt:11.5 windspeed:0.0 winddir:--- windrun:0.00 windhigh:0.0 windhidir:--- windchill:14.8 heatindex:14.7 thwindex:14.7 bar:1026.2 rain:0.00 rainrate:0.0 heatdd:0.002 cooldd:0.000 intemp:23.3 inhum:46 windsamp:23 windtx:1 iisrecept:100.0 arcint:1

You're going to have to create the data input method, graph template and data template. You might want to use other weather templates on the forum for a guide.

1) make sure the data input method fields match the ones the script spits out.
2) you'll need to update the rest of the associated templates you used to match the fields my script spits out.

Turn the polling level in cacti to debug (Settings | Polling level) for one cycle and paste the output of the actual log file (./cacti/log/cacti.log). If it contains WEBLOG entries, then don't bother posting since they just clutter up the log. Turn off WEBEVENTS logging and try again.

Look for the data being returned by the script.
