client (check active) does not send values to the server

[flako]

hello
I'm using Zabbix 2.4, I have some desktop to the client (check active and Low-level discovery) fails to submit the values of the items to the server, communication with the server is because:
- The client recover that items must monitor
- The server automatically creates the host and make some items (not all) but does not show values in them.
- In the client log, I can see that makes sending (see 'JSON before sending') but then a 'JSON back [{"response": "success", "info", "processed: 0; failed: 15 ; total: 15; seconds spent: 0.000273 "}] '
- In the log of the server I manage not see anything associated with the client.

Do not know what else to look .. where should look to find the error?
(Sorry for using translate)

The client log:

Thanks for lleer up down here.

Just my point of view on the process of Active Monitoring.

1) Administrator install Zabbix Agent on the client's PC and configure at least three settings in zabbix_agent.conf:
# IP-address of Zabbix Server
Server=1.2.3.4
# IP-address of Zabbix Server for Zabbix Agent(active) monitoring
ServerActive=1.2.3.4
# Host name of the client's PC
Hostname=adserver.domain.com

2) Administrator create a host in Zabbix frontend with the same Hostname as it was configured in zabbix_agent.conf

3) Administrator create some items for new host and change the Type from "Zabbix Agent" to "Zabbix Agent(active)"

4) Zabbix agent on client's PC, using the settings from ServerActive=, request the list of active checks from server and starts to collect data for Active check.

5) Zabbix agent sent back to server the list of data, which were collected based on the list, got from the Zabbix server.


In your scenario, I cannot understand, why Zabbix Agent try to send data which (possibly) weren't configured as Items in web-interface.

If I'm wrong, please, show us:
- the screenshot of Host description
- The screenshot of Zabbix Agent configuration file
- The screenshot of Items, which configured as "Zabbix Agent(active)"
- the part of zabbix_server.log file where we can see, that client got some configuration from server
- the part of zabbix_agent.log file from client with request about configuration and reply about sending data back to server.
