Load Balancer and Disabled server

[fduranti]

Hi, I've a question that about how to check for View Connection Server/Security Gateway availability in regards of the use of a load balancer.

How configuration is something like this:

1) Internal users: 2 dedicated connection server with a load balancer

2) External internet users: 2 connection server (configured for RSA authentication and PCoIP tunneling), 2 DMZ Security Gateway bound 1-to-1 with the connection servers and 1 load balancer

What I have to monitor from the load balancer to be sure that users can connect and work intenally and externally?

From the infrastructure view I have of vmware view i should say

1) Internal Users LB: I'm monitoring HTTP, HTTPS, LDAP, JMS (4001) and AJP13 (8009)

2) External Users LB: I'm monitoring https only on the Security Gateway and JMS/AJP13 on the related Connection Server.

My problem is that I don't know exactly how to monitor for example if one of the 2 connection server bound to a Security gateway is "disabled" the protocol/ports will answer normally to LB (so it's up for it) but the users getting there will not be able to connect because the Connection Server is disabled.

Another problem can be related to ports answering but the program behind it not working correctly.

There's any clean documentation on what to monitor and how to monitor related to load balanced Connection Server/Security Gateway?

We're using haproxy at this moment and it seems stable and working correctly but I don't know what will happen in "unknown/strange" situation.

Thanks

You should have a http healthcheck doing a "GET /favicon.ico HTTP/1.0"

Have a look in these whitepapers for more info:

Hi Linjo,

I already check for status 200 and this will be ok if a server is down but if I disable the server from vmware view admin page it will continue to be available as http/https and will answer with status 200 to http/https query but it will not work and user will not be able to login.

There's a way to check/query the "enabled/disabled" status of a server via http?
