Project Notes
This plugin checks the temperature or humidity from a watchport sensor. The temperature and humidity checks are in separate files. Parameters : -w - warning threshold -c - critical threshold -p - device port, default it /dev/ttyUSB0 Add the nagios user to the 'dialout' group to allow access to the serial port. When I first made this, I had issues with the USB sensor locking up after every read. To get around this, I made a version to reset the USB device after every read. See the github page for this version: https://github.com/nsafran1217/check_watchport I added an ACL to the USB device file to allow nagios write access. I added a udev rule so this ACL is added when the device is plugged in. Example, you will have to change the identifiers: SUBSYSTEM=="usb", ATTRS{idProduct}=="0305", ATTRS{serial}=="V72983794-0", ACTION=="add", RUN+="/bin/setfacl -m u:nagios:rw- /dev/$name"
