Global Positioning System demon (GPSD)

1. Download the script onto the host.

wget https://raw.githubusercontent.com/librenms/librenms-agent/master/snmp/gpsd -O /etc/snmp/gpsd

1. Make the script executable.

chmod +x /etc/snmp/gpsd

1. Edit your snmpd.conf file, usually /etc/snmp/snmpd.conf, and add:

extend gpsd /etc/snmp/gpsd

1. Restart snmpd on your host.

LibreNMS discovers the application automatically, as described at the top of the page. If the discovery fails, do the steps under the SNMP Extend heading at the top of the page.

If a timeout occurs, configure it as below below. If time gpspipe -w -n 20 is regularly longer than what your SNMP time out is for, this is required.

For cron...

*/5 * * * * /etc/snmp/gpsd 2> /dev/null > /var/cache/gpsd.snmp

For snmpd.conf...

extend gpsd /usr/bin/cat /var/cache/gpsd.snmp

If this device has no agent, install the agent and copy the gpsd script to /usr/lib/check_mk_agent/local/

You can need a change to $server or to $port.

Verify it is working by running /usr/lib/check_mk_agent/local/gpsd
