Zabbix web monitoring issue/clarification

[Mechanix]

Hi@ all,

I have a weird problem setting up web monitoring for a host.

Let me go a little bit into detail: we use Zabbix 3.2 server and 3 zabbix proxies.
One of the zabbix proxy is monitoring a host (HOST A) which is a HTTP Proxy (Squid).

Now, I want to set up web monitoring from this host through squid.
In the web scenario I´ve setup the HTTP proxy option to http://localhost:3128 but
the check fails with:

 Step "test" [1 of 1] failed: Couldn't connect to server: couldn't connect to host

Zabbix Server -- -> Zabbix Proxy ---> Host A (Squid/3128) ---> Internet


Any hints are much appreciated.

sorry to bump this. Any hints?

[Mechanix]

no one is using this scenario? Is it even possible? Thx

Any hints on the Squid that the zabbix proxy is actually connecting ?
Ping test from zabbix proxy to Squid Host is successful ?

Hi,

thank you for your reply. Yes, on the squid VM there is the zabbix-agent running and is monitored by zabbix proxy (Linux Template etc.)

Inside Zabbix GUI, I selected the squid host and added a web scenario; nothing special just a http check on http://leo.org

The question is now who is doing the HTTP request: the squid VM (zabbix-agent) or the zabbix-proxy?

Cheers

C.

As far as I know, the moment you monitor a host with a proxy the proxy does all the things.
Thats the beauty of a zbx proxy. Zbx server only evaluates and stores the data sent by the proxy.

So the proxy will take care of the web monitoring.

Here is the original feature request:

Aha ok, then I have to open the firewall ports from the zabbix proxy not the actual squid host. I wasn´t aware of that.

I was confused because you can select the squid vm host (which is monitored by the zabbix proxy) and add there a web scenario. First I thought the source of the HTTP request is the squid host itself.

Thanks a lot! Now everything is working as expected.

Glad I could help
