Briklets humidity and motion detector with nagios

[luca219]

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

We already cover this in the documentation of the Starter Kit: Server Monitoring. You can find a script there that already does what you ask for:

thanks for replay,

i tried this script, but show always "motion detected"

 

/usr/lib/nagios/plugins/check_tf_temp_ext.py -H localhost -u sKh -t motion_detector

motion detected

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.

yes

if self.connected_type == TYPE_MOTION_DETECTOR:
            if val == 1:

was the problem.

Now work fine, thanks

I noticed that the "check" does not work with pnp4nagios.

probably the output isn't in correct format.

http://docs.pnp4nagios.org/pnp-0.6/perfdata_format

 

someone has already seen the problem, you have any suggestions?

[photron]

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.

you give me some suggestions for how to do?

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)
