How can GTM will mark a Web Server down, if associated App Service is down

Hi,

 

In my setup I have followings. * F5 GTM * F5 LTM * Web Server (only one qty currently) * App Server (only one qty currently)

 

Setup is identical across two DCs, and we want GTM feature to be used for dynamic failover.

 

GTM will track the Web Service (Up/Down state), so that it can revert the User's DNS query response. Important point is that Web Server should show UP only when it's corresponding App Service is UP. My query is that how can we configure GTM/LTM in such a way that even though Web Service is up, but if it's corresponding App Service is down then GTM should consider that Web is down.

 

Basically I want to use some Health monitor for Web Server, which is dependent on the health status of App Service.

 

Please suggest.

 

Regards, Arun

    You could have your app developer that creates a page that will query the application (for example a database query) and if the response is successful display "success" on the page. Then you can create a monitor to verify that the page returns "success". This way you can validate that the web server and the applications are all up and responding.
