Briklets humidity and motion detector with nagios


Recommended Posts

Posted

hi all,

i need monitor server room with nagios and briklets.

I followed this wiki for temperature

http://www.tinkerunity.org/wiki/index.php/EN/Projects/IT_Infrastructure_Monitoring_-_Nagios_Plugin

and I followed base code

http://www.tinkerforge.com/en/doc/Software/Bricklets/MotionDetector_Bricklet_Python.html#motion-detector-bricklet-python-api

for check motion detector and

http://www.tinkerforge.com/en/doc/Software/Bricklets/Humidity_Bricklet_Python.html#humidity-bricklet-python-api

all work fine.

I need to integrate motion sensors and humidity in nagios.

Can anyone give me some guidance?

I can find a wiki for this?

 

regards

Ah, there was a bug in the script. It said "motion detected" if actually not motion was detected. It said "no motion detected" if actually motion was detected.

 

I've fixed this now.

 

There is a blue LED on the Motion Detector Bricklet that is on if motion is detected and is off if no motion is detected. You should now see that the script output matches the LED state.

Correct the output of the script doesn't follow the format pnp4nagios expects.

 

The data pnp4nagios expects is all there, you just have to modify the print statements in the script to output them in the format pnp4nagios expects.

There are several print statements in the code like this one:

 

print "CRITICAL : %s too high %s %s" % (self.name, val, self.unit)

 

According to the link pnp4nagios expects

 

<whatever> | <label>=<value>;[<warn>];[<crit>];[<min>];[<max>]

 

to be printed. The script currently only prints the <whatever> part.

 

You can extend the print statements like this to add the part pnp4nagios is looking for:

 

print "CRITICAL : %s too high %s %s" % (self.name, val, self.unit) + " | " + self.name + "=" + str(val)
