Monitoring load balanced web site

Votes:

0

Hey there I have a failover setup of load-balancers - meaning I have two different IP-addresses that both serve the same URL I wish to monitor each of the involved ip-adresses for the URL in question. I thought that all I needed to do was:

  • Setup each load balancer as a device with its own DNS-name (or ip-address)
  • Setup an HTTP advanced sensor for each - with the URL of the externally known name for the site "https://site.domain.com"
  • Select "Do not inherit SNI from parent device.

I thought that this would make an http request to each of the devices, to make sure that they both return data for the external site name.

I cannot make this work though - it insists that it cannot reach the site.

My guess is that I have to define the DNS for the URL on the probe server - but since that is TWO different adresses, that won't do.

What an I doing wrong here ??????

Regards

Jørgen Lind
