Hi everyone,
I want to check the humidity and temperature of a room with a dht22 sensor.
So I installed the nessecary plugins wiringPi and lol_dht22. So now I'am able to check the Humidity/Temperature in the commandline.
But i want so see also the stats in the webinterface,that's why i create a humidity.sh and temerature.sh with the query in usr/lib/nagios/plugins and the commands in /etc/nagios/nrpe.cfg. And at least i assigned the query to the device.

But I get following error:
Return code of 13 for service 'Temperatur' on host 'raspberrypi' was out of bounds
(same Error for Humidity)

Most likely when you are executing from the command line you are doing this as the root user.

I suggest you sudo as the nagios user and then execute the command again and see what error it reports.

Oh your right, thanks dude.
I guess Iam on the right way now, but i have still an error message.

(No output on stdout) stderr: sudo: /usr/lib/nagios/plugins/dht22-temperature.sh: command not found

But i created the commands in the commands.cfg and in the plugins directory

Code: Select all

define command {
command_name    check_hum
command_line    sudo /usr/lib/nagios/plugins/dht22-humidity.sh
}

Code: Select all

define command {
command_name    check_temp
command_line    sudo /usr/lib/nagios/plugins/dht22-temperature.sh
}

And also

You need to mark these executable

Code: Select all

chmod +x /usr/lib/nagios/plugins/dht22-temperature.sh
chmod +x /usr/lib/nagios/plugins/dht22-humidity.sh
