UserParameter Not Supported Zabbix 1.8.3

[Axilla]

Environment:
Zabbix 1.8.3
Agent 1.8.3
HAProxy(pulling the data using socat and Unix Socket Commands)

Things I've checked:
Hostname in zabbix_agentd.conf matches the Host in Zabbix Frontend.

UserParameter is in the zabbix_agentd.conf running on the HAProxy server.

I'm trying to write a UserParameter that will monitor the Status of proxies in HAProxy.

UserParameter=haproxy.blah01.status, echo "show stat" | socat stdio /tmp/proxystats | grep -i 'www.blah.com,www.blah.com.01' | sed 's/,/\ /g' | awk '{print $31}'

This is unsupported by zabbix, but if I do the following in CLI it returns the value i'm looking for.

echo "show stat" | socat stdio /tmp/proxystats | grep -i 'www.blah.com,www.blah.com.01' | sed 's/,/\ /g' | awk '{print $31}'

L7OK

also if i do zabbix_agentd -c /etc/zabbix/zabbix_agentd.conf -p

I see:

haproxy.blah01.status [t|L7OK]

which is correct, but the web interface says Unsupported and has no data.

I found something additional to add. In my zabbix_agentd.log this is showing up.

sh: socat: command not found

Resolved:

had to call full path to socat.
