Web monitoring behind load balacer

[kovas]

Hi,

we have site that we want to monitor behind load balancer. We can not user host name in the URL like: http://<server_name>/index.html. We have to use correct URL to both web servers.

Is there any way to monitor site straight on Web server, but not thought load balancer IP?

It depends on how the web server is setup, but assuming you can get direct network access to the servers and the web server is configured properly you can monitor both the individual/server URL's and the load balanced URL.

Actually frequently we have both setup, we monitor the VIP as a critical alert and the individual server URL's (either by DNS or IP Address) as a minor alert.

the problem is that SharePoint does not except access to individual servers like http://<server_name>/index.html

The only way we can monitor is to use live URL: http://FQDN/index.html

And this URL goes through Load Balancer.

Is any way to monitor both web servers by dynamically changing IPs for that URL or any other way?

In most IIS sites you should be able to setup host headers, seems this is more of a pain with sharepoint then your average website though.

You might be able to create some sort of script, but I don't think zabbix can do this type of dns redirection out of the box.

I did find this link which seems to go through some work around for adding host headers to sharepoint though.

You can use* webmonitoring with custom header, see https://www.zabbix.com/forum/showthread.php?t=47903

* it depends on your network/webserver/... setup

I got your idea, if there are no other solutions with zabbix, we will try with bindings, thank you for answers
