 Description   

Hi,

today I upgraded my pfsense from 2.6.0 to 2.7.0 but I forgot to check if the Zabbix agent is compatible. Basically the agent seems to be running but I can see the following error in the console:

PHP ERROR: Type: 1, File: /root/scripts/pfsense_zbx.php, Line: 817, Message: Uncaught TypeError: count(): Argument #1 ($value) must be of type Countable|array, null given in /root/scripts/pfsense_zbx.php:817
Stack trace:
#0 /root/scripts/pfsense_zbx.php(863): pfz_dhcp_get('failover')
#1 /root/scripts/pfsense_zbx.php(876): pfz_dhcp_check_failover()
#2 /root/scripts/pfsense_zbx.php(1091): pfz_dhcp('failover', NULL)
#3 {main}

 

Can you please check and fix?

Thanks in advance and best regards

Florian

I have experienced the same issue.
I solved it by disabling the Zabbix item "DHCP Failover Pool Problems".

Our pfSense-cluster does not use the dhcp function, so no problem for us if this is not monitored.

Maybe this helps to solve the problem:
The item key in Zabbix is this:
pfsense.value[dhcp,failover]

@Jeff Bremer,

thanks for your hint. I will give it a try.

Update: after 3 days I can confirm the workaround just works.
