Custom CONFIGURATION OF TRIGGERS

[mackhy]

Hi
I would Like to customize the following trigger via the clone option:

{vision:net.tcp.service[http].last(0)}=0

to monitor a http service on a custom port of 7777 see netstat below:

[root@vision ~]# netstat -tnap
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 127.0.0.1:7200 0.0.0.0:* LISTEN 8334/httpd
tcp 0 0 0.0.0.0:7777 0.0.0.0:* LISTEN 8334/httpd
tcp 0 0 0.0.0.0:10050 0.0.0.0:* LISTEN 24145/zabbix_agentd

As per the Zabbix manual the correct syntax is the following:

{vision:net.tcp.service[http,,7777].last(0)}=0

But we get the following error when we try to save the trigger:
ERROR: Cannot add trigger
* No such monitored parameter (net.tcp.service[http,,7777]) for host (vision)

What are we doing wrong, as you can see the http service is running via the netstat output.

Thanks

You need to create item net.tcp.service[http,,7777] first before you can use it in a trigger expression.

Item net.tcp.service[http] will monitor HTTP on port 80.
