Zabbix Template for pfSense

pfSense Zabbix Template

This is a pfSense active template for Zabbix, based on Standard Agent and a php script using pfSense functions library for monitoring specific data.

Tested with pfSense 2.7.x, Zabbix 6.0.

I'm actively maintaning template only for the current Zabbix LTS Release. Newest features will be explicitily added on current LTS.

What it does

Template pfSense Active

• Network interface Discovery and Monitoring with User Assigned Names
• Gateway Discovery and Monitoring (Gateway Status/RTT)
• OpenVPN Server Discovery and Monitoring (Server Status/Tunnel Status)
• OpenVPN Clients Discovery and Monitoring (Client Status/Tunnel Status)
• CARP Monitoring (Global CARP State)
• Basic Service Discovery and Monitoring (Service Status)
• pfSense Version/Update Available
• Packages Update Available
• Certificate Discovery and Monitoring

Template pfSense Active: OpenVPN Server User Auth

• Discovery of OpenVPN Clients connected to OpenVPN Servers in user auth mode
• Monitoring of Client Parameters (Bytes sent/received, Connection Time...)

Template pfSense Active: IPsec

• Discovery of IPsec Site-to-Site tunnels
• Monitoring tunnel status (Phase 1 and Phase 2)

Template pfSense Active: Speedtest

• Discovery of WAN Interfaces
• Discover public IP Address/ISP Name of WAN Interfaces
• Perform speed tests and collect metrics

Configuration

First copy the file pfsense_zbx.php to your pfsense box (e.g. to /root/scripts).

From Diagnostics/Command Prompt input this one-liner:

curl --create-dirs -o /root/scripts/pfsense_zbx.php https://raw.githubusercontent.com/rbicelli/pfsense-zabbix-template/master/pfsense_zbx.php

Then install package "Zabbix Agent 6" (or "Zabbix Agent 5") on your pfSense Box

In Advanced Features-> User Parameters

AllowRoot=1
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
UserParameter=pfsense.discovery[*],/usr/local/bin/php /root/scripts/pfsense_zbx.php discovery $1
UserParameter=pfsense.value[*],/usr/local/bin/php /root/scripts/pfsense_zbx.php $1 $2 $3

Please note that AllowRoot=1 option is required in order to correctly execute OpenVPN checks and others.

Also increase the Timeout value at least to 5, otherwise some checks will fail.

Then import xml templates in Zabbix and add your pfSense hosts.

If you are running a redundant CARP setup you should adjust the macro {$EXPECTED_CARP_STATUS} to a value representing what is CARP expected status on monitored box.

Possible values are:

• 0: Disabled
• 1: Master
• 2: Backup

This is useful when monitoring services which could stay stopped on CARP Backup Member.

Setup Speedtest

For running speedtests on WAN interfaces on the latest pfSense CE (2.7.2), it's recommended to check the available speedtest package first using:

pkg search speedtest

This will provide you with the latest package information. To install the speedtest package, use the following commands in Diagnostics/Command Prompt: Then, setup the system version cronjob with:

/usr/local/bin/php /root/scripts/pfsense_zbx.php sysversion_cron

pkg update && pkg install -y py311-speedtest-cli

Make sure to replace py311-speedtest-cli with the correct package name based on the results of the pkg search speedtest command.

Speedtest python package could be broken at the moment, so you could need an extra step, only if manually executing speedtest results in an error: download the latest version from package author's github repo.

curl -Lo /usr/local/lib/python3.8/site-packages/speedtest.py https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py

For testing if speedtest is installed properly you can try it:

/usr/local/bin/speedtest

Then, setup the cronjob with:

/usr/local/bin/php /root/scripts/pfsense_zbx.php speedtest_cron

Remember that you will need to install the package on every pfSense upgrade.

Speedtest template creates a cron job and check for entry everytime Zabbix requests its items. If you want to uninstall the cron jobs simply run, from Diagnostics/Command Prompt:

/url/local/bin/php /root/scripts/pfsense_zbx.php cron_cleanup

pfsense-zabbix-template's Issues

Gateway error with new line before status

I don't know exactly why, but one of my server when i try get gateway status i receive data line:

none

To fix it i change a link on zabbix agent settins to use | tail -1

...
UserParameter=pfsense.value[*],/usr/local/bin/php /root/scripts/pfsense_zbx.php $1 $2 $3 | tail -1

I hope to help someone who has the same problem

Wrong template group name

The openvpn template has group name with lowercase d

            <groups>
                <group>
                    <name>Templates/Network devices</name>
                </group>
            </groups>

It causes a new group to be created.

List of service which are stopped on CARP Slave

You did wrote on your Script the following

//List of service which are stopped on CARP Slave.
//For now this is the best way i found for filtering out the triggers
//Waiting for a way in Zabbix to use Global Regexp in triggers with items discovery

Here an Input/Idea. Don't know if you like to use, because it needs some little work by the user, but i think it's more flexible then hard in the Code.

On your Template you add a Macro called, as an example, which has the value '1' (or '0')

{$CARP.SLAVE.SERVICES}

On your Trigger for the Services, you adding to the expression

and ({$CARP.SLAVE.SERVICES:"{#NAME}"}=1

If you now add the Template to your Slave-Host, you can add the following Macros and no Trigger should be fired. You can also use it on the Master (and Slave) if you did stop any Service (for whatever reason) manually and no Trigger should be fired.

{$CARP.SLAVE.SERVICES:"haproxy"}
{$CARP.SLAVE.SERVICES:"openvpn."}
{$CARP.SLAVE.SERVICES:"openvpn"}

*** Would be better to add also the Name of the Services instead only of the Description. Because with that, the Macro which needs to be added is shorter and more readable.

Escape @ at openvpn_server_uservalue

In zabbix agent logs:
18062:20201221:132549.756 active check "pfsense.value[openvpn_server_uservalue,3+user@domain,virtual_addr]" is not supported: Special characters ", ', ", `, *, ?, [, ], {, }, ~, $, !, &, ;, (, ), <, >, |, #, @, 0x0a" are not allowed in the parameters.

OpenVPN Discovery Issue

I can't get OpenVPN Server status and port

Service status check issue

Hello,

Thank you for your great work on this monitoring script. I found a small mistake in the function pfz_service_value that affects services with the space in the names, for example, FRR package.

    [1] => Array
        (
            [name] => FRR zebra
            [rcfile] => frr.sh
            [executable] => zebra
            [description] => FRR core/abstraction daemon
        )

    [2] => Array
        (
            [name] => FRR staticd
            [rcfile] => frr.sh
            [executable] => staticd
            [description] => FRR static route daemon
        )

    [3] => Array
        (
            [name] => FRR bfdd
            [rcfile] => frr.sh
            [executable] => bfdd
            [description] => FRR BFD daemon
        )

    [4] => Array
        (
            [name] => FRR bgpd
            [rcfile] => frr.sh
            [executable] => bgpd
            [description] => FRR BGP routing daemon
        )

    [5] => Array
        (
            [name] => FRR ospfd
            [rcfile] => frr.sh
            [executable] => ospfd
            [description] => FRR OSPF routing daemon
        )

    [6] => Array
        (
            [name] => FRR ospf6d
            [rcfile] => frr.sh
            [executable] => ospf6d
            [description] => FRR OSPF6 routing daemon
        )

When Zabbix discover the items using another function pfz_services_discovery, you are replacing space with the "__"
$json_string .= '{"{#SERVICE}":"' . str_replace(" ", "__", $service['name']) . $id . '"';

Then, when Zabbix checking service status, you are trying to replace "" with the spaces in the original service name and comparing it with the name from Zabbix with the "", which is wrong.

foreach ($services as $service){
          $namecfr=str_replace("__"," ",$service["name"]);
...
          if ($namecfr == $name){
...

The replace should be in the same way as in the service discovery function. Could you please fix this in your PHP file.
$namecfr=str_replace(" ", "__", $service["name"]);
Thanks a lot again!!

OpenVPN Carp Status

When using PfSense in a redundant setup, not all OpenVPN instances are identified as enabled on CARP Slave = 0

I was able to identify a potential cause.

$stopped_on_carp_slave = array("haproxy","openvpn.");

changed to

$stopped_on_carp_slave = array("haproxy","openvpn.","openvpn");

And all OpenVPN instances now report as disabled on carp slave.

Gaetway status reporting value as 5

I have multiple gateways, but one regular reports its status as 5 - this isn't one of the status values that the template/graphs knows and marks the gateway as down in zabbix even though it isn't in the pfSense GUI

Can't run discovery or get any data

Hi, after following the instruction but I can't get any data into my zabbix server. The most data I want is openvpn. Any solution to find out what happen?

Thanks & Regards

Services not showing

https://ibb.co/m0X8XPP
https://ibb.co/mDt5QBZ
https://ibb.co/pQSCDNf
https://ibb.co/VqS4Rm0

So for some reason the services feature isn't working for me on my negate SG-5100. All the other features work well but i'm not seeing any of the running services items getting any data.

I can run zabbix_get -s 127.0.0.1 -k pfsense.value and I get the array field as seen in the photo and it lists all the services, but there isn't any data underneath them.

zabbix_get -s 127.0.0.1 -k pfsense.value[services_value,dhcpd,status]

returns no match.

I'm not that worried about the service status but would be nice. Thanks so much for all that you do. I'm running Zabbix 5.0 agent and Server. All the other features work great, just the services don't list for me! I have downloaded the php file as in the read me - hince all the other features work great.

Openvpn client status

Hey there,
Tried using your template and php, but encountered a problem. When I run php script.php 1 status, in most of the code the status is up, but in the end returns 0. Now when I looked at it I saw this
line 243 $value = pfz_valuemap("openvpn.server.client", $value);
line 457 case "openvpn.client.status":
Am I wrong in assuming, that openvpn.server.client key should be openvpn.client.status instead?

not showing alerts on services though proxy

Hi
I was wondering if this has happened to someone else, currently i had pfSense working with the template as zabbix agent active, but i changed the agent that goes though the proxy then to the zabbix server, it shows all the info except the services, i tried to turning it off and back on but it does not show any alert i checked if there was an issue on the discovery so far nothing, only on the data shows out greyed out
currently have the proxy as active rather then passive

gateway allredy down

hi. I'm using your template without success. everything was great. I added a new PFsense and got the gataway down event. I found out that there is a difference in /root/scripts/pfsense_zbx.php. But the file version has not changed. Is this an error or were there changes?

Openvpn: Server mode Peer-to-peer

Hi

I just tried the template today and it works great. The only thing I have noticed so far it's that it will show a openvpn server as offline if it's in peer-to-peer mode. The status check seems to only check for the 3 remote access modes.

The check for peer-to-peer mode should be p2p_shared_key and p2p_tls

Zabbix 5.0 and PFSense 2.4

I have followed your instructions and used the Zabbix Agent 5.0 on PFSense. I cannot get it to work. If I use the FreeBSD, it connects.

Zabbix Server does not connect to pfSense with template

Excuse me, but I really can't understand the reason for this situation.
I followed the instructions to install and register the Zabbix pfSense template.
I installed the Zabbix 4.0 agent on the pfSense configured with the advanced settings, I copied the php file in the path / root / scripts / inside the pfSense and loaded the templates into the Zabbix Server.
Nothing to do Zabbix does not connect to the pfSense agent.
So I tried to hook a generic template for the network by removing the advanced settings and the server hooks up immediately.
Where am I wrong?
Thank you !

Squid service wrongly detect as down

On my pfsense box squid service is detected as down, but it is running. Only reverse proxy service is stopped.

With OPNSense

Hi,

Thanks for your work.

I want to install it to OPNsense... (last version).

1. I've a Zabbix Agent and no Zabbix Active Agent.
   So, I've changed All Item with Zabbix Agent (no Active)
   --> OK

2. Zabbix Agent UserParameter web interface... dont work with specials characters (exemple : *)
   So, I've add all UserParameter into a new .conf file to /usr/local/etc/zabbix_agentd.conf.d/ folder
   --> OK

After this, I'll try with pfsense.value[gw_status] item, but I've an error on my Zaxxib Server :

Warning: require_once(globals.inc): failed to open stream: No such file or directory in /root/scripts/pfsense_zbx.php on line 10

Fatal error: require_once(): Failed opening required 'globals.inc' (include_path='/usr/local/etc/inc:/usr/local/www:/usr/local/opnsense/mvc:/usr/local/opnsense/contrib:/usr/local/share/pear:/usr/local/share') in /root/scripts/pfsense_zbx.php on line 10

PHP Script is on
/root/scripts/pfsense_zbx.php

I don't have globals.inc file to OPNsense

Script work it with OPNsense ?

4 Discovery Rules Not Supported

Hi.
So i am running zabbix 4.2.8 and the pfSense box is on 2.4.4.
The install on the pfSense box was done by a colleague and i am trying to figure out if its an issue on my (Zabbix) side or if the installation was done incorrectly.

4 of the discovery rules come up as unsupported and this is what they say.

(Invalid discovery rule value: cannot parse as a valid JSON object: invalid object format, expected opening character '{' or '[' at: '

radvd on carp slave

The service Router Advertisement Daemon(radvd) on a carp ip slave for the RA interface should be stopped. This template flags the trigger.

{removed:pfsense.value[service_value,radvd,status].last()}=0 and ( ({removed:pfsense.value[service_value,radvd,run_on_carp_slave].last()}=1 and {removed:pfsense.value[carp_status].last()}=2) or ( {removed:pfsense.value[carp_status].last()}=1) or ({removed:pfsense.value[carp_status].last()}=0) )

Above is what the discovery rule created. On the Dashboard it shows as "Down (0), Yes (1), Backup (2)"

OpenVPN Server Status

Checking status of OpenVPN does not work for mode Remote Access ( SSL/TLS )(server_tls)

Current code in pfsense_zbx.php
if ( ($server['mode']=="server_user") || ($server['mode']=="server_tls_user") ){

Modified code to

if ( ($server['mode']=="server_user") || ($server['mode']=="server_tls_user") || ($server['mode']=="server_tls")){

and the issue I was having appears resolved.

OpenVPN Client fStatus

Good evening.
I applied all the scrippts however
OpenVPN Client UDP4 Tunnel Status only collects 0 as a value, even though it has an active tunnel it does not collect the information, I tried to apply a javscript but even so the collection did not work.

Congratulations on collecting users by name and traffic.

False alarms?

Hi,
Currently installed on a few pfSense boxes but i keep getting false alarms, maybe possible changing to check every 5mins?
I normally get alerts saying WAN gateway down but 3 seconds later it shows resolved
Then i check pfSense on the quality of the gateway and didn't show anything odd.
Thank you

What if my ovpn status was "reconnecting; ping-restart".

Hello.

First, thank you for the amazing job.

I saw in preprocessor of openvpn server status a code for up, down e none status. One of my tunnels got "reconnecting; ping-restart" status. How can I preprocess that to a value?

Is this in php script?

For me an error appears

"Preprocessing failed for: reconnecting; ping-restart

1. Result: reconnecting; ping-restart:up=1:down=0:none=0
2. Failed: cannot perform regular expression "(up|down|none)(?=.*:\1=(\d))" match for value of type "string": pattern does not match"

sorry about my english.

Temp reading with netgate appliances.

For Netgate appliances they offer a temp reading.

So I've added the user agents

UserParameter=temperature0,sysctl -n dev.cpu.0.temperature
UserParameter=temperature1,sysctl -n dev.cpu.1.temperature

Which returns a text value of 32.0C. I'll try to make a custom trigger for it. Just wanted other netgate users to know.

Same files?

Hi,
i have download
template_pfsense_active.xml and template_pfsense_active_ovpn_user.xml
but is same file?
When i import in zabbix, only one template is created
thanks

Last Version of PHP file

Good Morning,

I use the previous php template in some pfsense boxes. I installed a new one this week and used the new php. All my gateways are alarmed as down. With data return 5 in zabbix. I went back to the old php and found that my links returned to receive 0 and returned to the UP status.

Best regards,

Zabbix 4.4

I'm having an issue with zabbix 4.4 that it won't pull any values - it works fine with the default FreeBSD template but I get the following error: Cannot send request: wrong item type.

Gateway always 5 ('Down')

Hi Riccardo

We've a pfSense Cluster and we did turn on the Option «Disable Gateway Monitoring». With that, the Gateway has the Status «Online (unmonitored)». Now we did some adjustments before using your Template and disabled the option «Disable Gateway Monitoring». So pfSense does active Ping its Gateway.

But your Template/Script does still show the Gateway as «Down» (5). I did not yet have the time to search the issue and check your Script. What i was able to test is, with the Template of Leonardo (https://github.com/lndgoncalves/zabbix-pfsense-gateway) i was successful - with the Template of Leonardo, the Gateway-Status is always correct.

Maybe you have any idea.

Alert timing ?

Hi,
I was looking around the template and was getting a tad bit alerts but it goes away real quick, Would it be possible to check every 3mins? i checked on the discovery which is every 30 seconds, but not sure if that's the option
Thank you

Triggers for Gateway Status based on third last value

I have a few gateway which ‘flap’ so I get a lot of triggers. I just wanted to check that the use of last(#3) was the intended behaviour in the triggers.

I assumed that this meant the value had to be in that state for the last 3 readings but that is not the case reading the following:

The function last uses a different meaning for values when prefixed with the hash mark - it makes it choose the n-th previous value, so given the values 3, 7, 2, 6, 5 (from most recent to least recent), last(#2) would return 7 and last(#5) would return 5.

Cannot send request: wrong discovery rule type.

Ciao Riccardo!
first of all.. kudos and thanks for this great job!

I've tried to import your template on a brand new Zabbix 5.0.3 server.

Everything works fine but autodiscovery rules not. When I try to "Execute Now" I receive this error:

Cannot send request: wrong discovery rule type.

If I change them to "Zabbix Agent" (so passive mode) they works fine. I've double checked and active check are enabled (all other items are working) and there is nothing that can explain why I'm receiving that error.

I've tried also on another setup based on Zabbix 4.4.10 but the error is the same.

I've solved by changing all the discovery rules to passive mode, but I'm trying to understand if there is someway to run them in active mode (I prefere due to better performance)

Thanks for your help!

Zabbix 5.0

Hi rbicelli,

First of all thanks for share.
I tried to make it work in Zabbix 5, without succes.

Will you make a test in 5.0, in a short time?

Best regards,

OpenVPN?

Hi,
I wanted to say thank you for this amazing template. Was just wondering is it possible to add the which user has connected and disconnected from their IP?

Thank you

Cannot create item: item with the same key "pfsense.value[service_value,captiveportal,status]" already exists.

we have this 2 error messages in Services Discovery

Cannot create item: item with the same key "pfsense.value[service_value,captiveportal,run_on_carp_slave]" already exists.
Cannot create item: item with the same key "pfsense.value[service_value,captiveportal,status]" already exists.

Maybe because my pfsense have 2 captive portal instances!

can anyone help me to change this and monitor 2 captive portal services?

Thanks in advanced.

select() failed: [4] Interrupted system call

Hey,
Sorry if this isn't an issue with the template (I'm not the best with zabbix yet) but since using this pfsense doesn't connect to the zabbix server. If I look at the log inside /var/zabbix-agent/zabbix-agent.log I can see that there is some sort of issue from the log. I have't changed any network configurations and had it working with a standard template before so I know there is no network setting blocking connections or anything like that.

As per instructions my timeout is set to 6 and the user parameters are set.
I have openVPN in use so I applied both templates if that makes a difference.

Do you know what is wrong from this or is it me?
... it's probably me being stupid :(

Crash: pfSense has detected a crash report or programming bug

Hi, today I got the error:

Trigger issue on Pfsense version : Cannot evaluate expression: expected numeric token at

Hello,

First, thanks for your perfect template and php file, this is exactly what i was looking for my homelab !

I got an error on the New version trigger and this is the details about it :
Cannot evaluate expression: expected numeric token at "2.4.5)<>(2.4.4_3)".

I'm running a Zabbix LTS server with your recently updated template.
Pfsense (fresh install < 4d) is on 2.4.4_3 version with an update pending.

Thanks for your help.

Cannot find pair with name "{#NAME}"

Just downloaded the latest update and my discovery rules are now saying,

Invalid discovery rule value: cannot find pair with name "{#NAME}".

All discovery but, Mounted filesystem discovery, show this.

I'm using the template_pfsense_active.xml.

If I roll back to the previous PHP file these errors go away
