Help with "Get value from agent failed: ZBX_TCP_READ() timed out"

[Egonimo]

Hello,

since a few days I have a problem that is driving me nuts. I call a UserParameter (PowerShell Script) to check the load of a Citrix TerminalServer Desktop.

While

***@zabbix:~$ zabbix_get -s *** -p 10050 -k "CitrixLoad[***]"
6168

works from within the console on Zabbix server, I get the message from the title the second I implement this in the webui. The funny part is, that it worked a few days before.

I have no idea what I am doing wrong or where I made a mistake. The only thing I changed was the execution policy for the PowerShell Script in the agent configuration. But I thought it would affect both, the poll from webui and cmd. I restartet both, client and server, a dozen times.

How many seconds does it take to execute the zabbix_get command? Is the timeout setting for that number of seconds or more set for both Zabbix server and Zabbix agent?

[Egonimo]

Yes, I used the setting 30s for both, the script from the command line takes 2 seconds to finish. The timeout from the WebUI comes after 3 seconds. Somehow it feels like the value in the configuration is ignored.

I have the same problem. Zabbix_get takes 2 seconds on proxy and it shows the JSON data. However the frontend says : "

• Get value from agent failed: ZBX_TCP_READ() timed out
