Force agent to push data

[KaeruCT]

Hello,

I need to force the Zabbix agent to send the data to the Zabbix server, on demand.

I am using active checks because my machines are behind a firewall, however, I need to open the port on the firewall and then close it (don't ask why...) after the agent has finished.

I wonder if it's possible to have a script like this (pseudocode):

# set up firewall stuff before sending data
iptables -A OUTPUT -p tcp -d zabbix.server.lan --dport 10050 -j ACCEPT
./zabbix_agent --force-send
# undo firewall stuff after the agent has sent the data
iptables -D OUTPUT -p tcp -d zabbix.server.lan --dport 10050 -j ACCEPT

I already thought of restarting the agent, but that seems a bit hacky to me.

Thanks for any suggestions you can give me.

Zabbix sender could do the trick, depending on your needs.
