Raspberry Pi GPIO Monitor

This SNMP extend script monitors the IO pins and the sensor modules on your GPIO header.

1: Install wiringpi on your Raspberry Pi. On a Debian-based system, run:

sudo apt-get install wiringpi

2: Download the script to your Raspberry Pi.

```bash
wget https://raw.githubusercontent.com/librenms/librenms-agent/master/snmp/rpigpiomonitor.php
-O /etc/snmp/rpigpiomonitor.php
```

3: (optional) Download the example configuration to your Raspberry Pi.

```bash 
wget https://raw.githubusercontent.com/librenms/librenms-agent/master/snmp/rpigpiomonitor.ini
-O /etc/snmp/rpigpiomonitor.ini
```

4: Make the script executable:

```bash
chmod +x /etc/snmp/rpigpiomonitor.php
```

5: Create or edit your rpigpiomonitor.ini file for your setup.

6: Validate your configuration with rpigpiomonitor.php -validate.

7: Edit your snmpd.conf file (usually /etc/snmp/snmpd.conf) and add:

```bash
extend rpigpiomonitor /etc/snmp/rpigpiomonitor.php
```

8: Restart snmpd on your Raspberry Pi. If LibreNMS already holds the Raspberry Pi, do a manual rediscovery.
