Ok, I got a hunch. I think I may have made my rrds as counters instead of gauges. Is there a quick and easy way to confirm that?

I use this dinky little script to update an rrd: #!c:\perl\bin\perl -w use LWP::Simple; $_ = get("http://weather.noaa.gov/weather/current/KAUS.html";); if (/<TD><FONT FACE="Arial,Helvetica"> (.*?)%/) { $hum = "$1"; } if (/<TD><FONT FACE="Arial,Helvetica"> (.*?) F/) { $temp = "$1"; } #printing the variables and time are just for me to look at print "$hum\n"; print "$temp\n"; print time, "\n"; system("rrdtool update weather.rrd N:$hum:$temp"); I run that every 5 minutes. When I do a fetch; rrdtool fetch weather.rrd AVERAGE --start -8640 I get: ~snip~ 1044558000: -1.#IND000000e+000 -1.#IND000000e+000 1044558300: -1.#IND000000e+000 -1.#IND000000e+000 1044558600: 0.0000000000e+000 0.0000000000e+000 1044558900: 0.0000000000e+000 0.0000000000e+000 1044559200: 0.0000000000e+000 0.0000000000e+000 1044559500: 0.0000000000e+000 0.0000000000e+000 1044559800: 0.0000000000e+000 0.0000000000e+000 1044560100: 0.0000000000e+000 0.0000000000e+000 1044560400: 0.0000000000e+000 0.0000000000e+000 1044560700: 0.0000000000e+000 0.0000000000e+000 1044561000: 0.0000000000e+000 0.0000000000e+000 1044561300: 0.0000000000e+000 0.0000000000e+000 1044561600: 0.0000000000e+000 0.0000000000e+000 1044561900: 0.0000000000e+000 0.0000000000e+000 1044562200: -1.#IND000000e+000 -1.#IND000000e+000 I get 0's where I'd expect a humidity and a temperature number. So I must be doing something wrong. My variables are correct, as they print out the expected data. Could someone throw me a clue as to what I am doing wrong? TIA!

I have a area graph that goes from 0 to 100, the area is green in color. Is it possible to have an upside down area (starting at 100 and going down) which is red. So when the value of the green color data is less than 100 you see that value in a red area. > > If the value is 100 you see no red if the value is 60 you see 40 red, 0-60 is green area, 60-100 is a red area. > You can make a CDEF with a value of 100 and make it a red area in the graph, then make an area with your data in green. As long as you use AREA in both cases they should overlay and you get the effect you want. -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
