Web scenario fails

[yousan]

Hello.

Web scenario fails.
---
Error: Timeout was reached
---

I can access to the target web URL with wget or curl on zabbix server host.

---
shell> wget -O /dev/null http://www.example.com
...
200 OK
...
---

I guess DNS lookup or something bad.
I found same message on zabbix/zabbix_server.log.
I want to more information about the failing. How can I get the debug info?

Thanks.

Increase your step parameter Timeout:

Set value regarding of your current load time:
shell> time wget -O /dev/null http://www.example.com

Hi jan.garaj. Thank you for your reply.

I understand how to set timeout value, thanks.

Now it is set 15 seconds, default value. It looks enough time to reach the servers (web hosts).

this is the test at the zabbix server host.
I added google.com web scenario as test but it failed in this case.

Saving to: `/dev/null'

wget -O /dev/null http://www.google.com  0.00s user 0.01s system 3% cpu 0.212 total

/**
In case google.com, google returns 302 alter to 200.
I have set 200 as expected value in web scenario, but it's not problem.
It successes correctly in other zabbix host.
Just I want to get debug information.

If you have some devel skill you can check it in source code level:

https://www.zabbix.org/websvn/wsvn/zabbix.com/trunk/src/zabbix_server/httppoller/httptest.c

If not, enable Zabbix server DebugLevel=4 and then check log file.
