-## Zabbix Template - pfSense

-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._
