How to monitor iptables rules' count with zabbix

[dsilenco]

hey all, how can i monitor my Ubutnu iptables rule count and if reaches some limit it will restart the service. Here is what i did:

zabbix.agent:
UserParameter=iptables.rule.count[*],sudo iptables --list --line-numbers | grep DROP | wc -l

item;
Key: iptables.rule.count[*]
Type: Numeric (unassigned)

Trigger:
{vgw1-stag:iptables.rule.count[*].count(30)}>1

No error. Enabled but doesn't do anything.

Thank you

Try running this command as a zabbix user.
Try to specify the full paths to wc, grep, etc.
