HVAC Sensor em01B

[crazyfrog]

Hi all,
i wan't to graph temperature and humidity with the websensor em01b. I successfully connected them with Nagios with the script from the website above, but i don't know how to use them witch cacti. Google isn't my friend in that case and a forum search doesn't help.

Does some one have an i Idea how i can do that?

Thanks

PS: The attached file is the Nagios Script which may can be used for cacti?

Hi Reinhard,
yes, thanks - i spend some time to modify the nagios script to work with cacti. Tomorrow i'll export the templates and share them with the community.

Danke erneut.

Try to start with this script. It needs the nagios plugin, but I think the output is ok. The IP address is hardcoded, but I guess you'll find a way to get it as a cacti variable.

Code: Select all

#!/usr/bin/perl

open (em01, "\/usr\/lib\/nagios\/plugins\/check_em01 192.168.0.10|");

my $lLineBuffer = <em01>;
chomp $lLineBuffer;

### TC: 18.9HU:33.4%IL    .1        Fri Oct 28 00:03:46 2005

my @lOutput = $lLineBuffer =~ /TC:\s*([0-9.-]+)\s*HU:\s*([0-9.]+)\s*%\s*IL\s*([0-9.]+).*/;

print "Temperature:@lOutput[0]Humidity: @lOutput[1]Illumination:@lOutput[2]";

Hi,

We (Esensors) have updated our plugin, released under GPL, to support Cacti.
This is a beta version.

It is available at http://www.eesensors.com/download.html

Any feedback is greatly appreciated. Please post improvements to this thread or contact us by email.

Thanks!

I tried it and it works fine. However, I did add a few things:

• Added a vertical label for all 3 graphs, (% for humidity, lux for illumination and celsius for temperature)
• Added current, average, min, max values at the bottom of the graph

I'm attaching the templates, I hope it will work for the others
