define Package/zabbix-extra-mac80211/description
An extra package for zabbix-agentd that adds a discovery rule for mac80211 wifi phy and many userparameters.
It contains an suid helper to allow zabbix-agentd to still run as zabbix user and not as root.
See https://openwrt.org/docs/guide-user/services/network_monitoring/zabbix for ready to use zabbix templates.
endef

define Package/zabbix-extra-network/description
An extra package for zabbix-agentd that adds a discovery rule for openwrt network interfaces.
The idea here is to discover only interfaces listed in /etc/config/network (discover br-lan and not eth0.1 and wlan0)
See https://openwrt.org/docs/guide-user/services/network_monitoring/zabbix for ready to use zabbix templates.
endef

define Package/zabbix-extra-wifi/description
An extra package for zabbix-agentd that adds a discovery rule for wifi interfaces and many userparameters.
As it uses libiwinfo, it works with all wifi devices supported by openwrt.
See https://openwrt.org/docs/guide-user/services/network_monitoring/zabbix for ready to use zabbix templates.
