Get value from agent error

[paulo.soares]

Hello!

Here, we are migrating from Zabbix 2.2 to 2.4, and in the meantime, the two servers are running, monitoring and being compared.

But we have an agent that reports correctly to the Zabbix 2.2, but on the Zabbix 2.4 we receive the error below:

Get value from agent failed: ZBX_TCP_READ() failed: [4] Interrupted system call

The server monitored is a MS Windows Server 2008 R2 64-bit.
I used a telnet command from both ZabbixServers and they reached the monitored server on port 10050.

Any idea what can be causing this issue?
Thanks for all help!

Can you confirm that the Agent is able to speak to the proxy/server assigned to it on port 10051?

I can only test on Zabbix servers, and, using a simple telnet command, I can't connect with the agent from any of the two zabbix servers.

Any other idea?

Well, you can put the server in a higher DebugLevel (4 is usually helpful to me). If you can do the same on the Agent, even better.

However, it might be helpful if you were to also do a full packet capture from the server. Something along the lines of "tcpdump -X -s 1500 -w /tmp/mypacketcapture -vvnlieth0 host 172.16.0.1" obviously, replacing the relevant information with the hostname, interface, blah blah.

Will be happy to look at the results if you wish -- probably would have to send them in email.

Solution!

Hello,

Yesterday i tried other solution: only removed the blank spaces between the IPs of Zabbix servers... Sorry, i don't read carefully the header of parameter on the zabbix_agentd.conf archive.

Thanks for all help.
