 Le lien avec ce template a été retiré car il n'existe pas de version "Active" du template par défaut dans Zabbix. Ne pas oublier de le rajouter dans les templates liés.
 
 _ps: pour avoir la version "Active" d'un template il suffit de cloner le template "Passif" et de modifier le type de chaque élément._

+## pfSense Zabbix Template
+FreeBSD template pfSense-oriented:
+  - complete remodeling of memory monitoring
+  - metrics from the memory buffer used by the network (_MBUF_)
+  - metrics on State Table usage
+  - improved visibility of graphics
+  - revised triggers
+
+#### We talk about it on our blog
+[PfSense Monitoring with Integrated Zabbix Agent](https://www.keenton.com/supervision-pfsense-avec-agent-zabbix-integre/)
+
+#### Requirements
+  - _admin_ access on Zabbix server and firewall pfSense
+
+#### Zabbix Server
+Nothing special, just import both templates, create the host for pfSense and link it to the appropriate template (active or passive).
+
+#### Zabbix Agent: _User Parameters_
+In Zabbix agent config on pfSense, you must display the advanced configuration options and add to the _User Parameters_ field that just appeared:
+    UserParameter=pfsense.states.max,grep "limit states" /tmp/rules.limits | cut -f4 -d ' '
+    UserParameter=pfsense.states.current,grep "current entries" /tmp/pfctl_si_out | tr -s ' ' | cut -f4 -d ' '
+    UserParameter=pfsense.mbuf.current,netstat -m | grep "mbuf clusters" | cut -f1 -d ' ' | cut -d '/' -f1
+    UserParameter=pfsense.mbuf.cache,netstat -m | grep "mbuf clusters" | cut -f1 -d ' ' | cut -d '/' -f2
+    UserParameter=pfsense.mbuf.max,netstat -m | grep "mbuf clusters" | cut -f1 -d ' ' | cut -d '/' -f4
+
+Commands used:
+  - `grep`: filter text by pattern.
+  - `netstat`: show network status.
+  - `cut`: cut out selected portions of each line.
+  - `tr`: replace characters (used here to replace the space sequences with a single space, necessary in some cases to properly use the `cut` command).
+
+##### _Timeout!_
+In Zabbix Agent config (on pfSense) you may need to increase the timeout value (set to 3 seconds by default). It is certainly the first thing to check on Zabbix Agent if you find yourself unable to retrieve some _User Parameters_ metrics.
+
+#### Template App Zabbix Agent
+The link with this template has been remove for the "Active" version does not exist by default in Zabbix. Do not forget to add it in the linked templates.
+
+_ps: you may create an "Active" template version by cloning the "Passive" one and changing the type of items._
