NimbostratusHi Kevin and Mike!
Thank you so much for your response. I am a newbie to F5 and in the process learning its awesomeness. To answer your questions:
-
What kind of HTTP request will truly identify a healthy (or unhealthy) SharePoint server? What URI is only available, or what response payload is only given if the SharePoint server is up and running? Do you need to provide credentials to make a request? Bala: HTTP 200 OK Response from the SP servers applications considered as healthy. Yes, we need to use NTLM to access the application pages. One thing that I would like to understand about the F5 HTTP monitoring is, is it capable of monitoring all the web applications through single GET string? In our case, we have five web applications published through the single virtual IP on F5, if we need to monitor all the five applications and making sure they are all up and running before F5 LTM passes the request, is it possible through the HTTP monitor? Our goal is to be able to monitor all the web applications on SharePoint servers ( Send the GET requests different web applications home pages .i.e. welcomePage.aspx, default.aspx and homepage.aspx) and making sure they are all healthy before passing the user request to the servers.

Using something better than Round Robin load balancing is your best first step. Least Connections and Observed methods are popular. Yes we are using the Least Connections (Member) for that rule.

iCall Script looks great, but I need some details on how to implement this in conjunction with iAPP SharePoint rule. Also noticed in that article that the BIG-IP needs to be on 11.4 or higher in order to get the iCall implemented. Ours is currently on BIG-IP 11.3.0 Build 3117.0 Hotfix HF5, not sure if its possible to update the Big-IP at this stage.
We do have a software (WMI Based) for monitoring the websites in our environment. Last time when we had an outage on the SharePoint application (App pool down) the F5 was still passing the request to the servers :( without even marking that node is down.
I really appreciate your help!
Regards
Bala
