Provide IPFire specific items for the Zabbix server to monitor: - Networking stats: - ipfire.net.gateway.pingtime: Internet Line Quality - ipfire.net.gateway.ping: Internet connection - ipfire.net.fw.hits[*]: Firewall hits - IPFire service states: - ipfire.services: JSON formatted state of all IPFire services using new ipfire_services.pl script.

Users can install the IPFire 2 Zabbix template-set provided here: https://share.zabbix.com/network-appliances/ipfire-2 to monitor these metrics. Or create their own template.
