Agentd -> My prog -> Sender -> Server

[safl]

Hello!

I'm trying to do a a setup where i poll the zabbix_agentd locally on the monitored host with a 'small prog', after polling for data the data will be send with zabbix_sender to the zabbix_server.
It's sort of an replacement for active checks until they become available in the Win32 client.
My question is, how to i get connect with my 'small prog' to the the agent? Can i simply open a socket and pass a string and i will get a return? Or how does it work?

Yup, open the socket, dump the full item string plus CR, expect characters back.

Make sure you configure agentd with the Server directive pointed to localhost however, otherwise it'll RST as soon as the socket's been opened.

So getting the "ZBX_NOTSUPPORTED" means that i need to change my zabbix_agentd.conf?

[araw]

That would be correct.

If zabbix_agentd doesn't know what you're asking for, it just says it's not supported.

# telnet host 10050
Trying x.x.x.x...
Connected to host (x.x.x.x).
Escape character is '^]'.

Hmmm weird behavior...
when i telnet to a linux host running zabbix_agentd i get a return like:

Trying xxx...
Connected to xx.
Escape character is '^]'.
version[zabbix_agent]
1.1alpha10
Connection closed by foreign host.

if i do the same on a windows host i get:
Trying yyy...
Connected to yyy.
Escape character is '^]'.
version[zabbix_agent]
ZBX_NOTSUPPORTED
Connection closed by foreign host.

Does the windows agent somehow behave differently?
