Yesterday I read Balance multiple View Connection Servers using HAProxy and realized that I have not published a recommendation for VMware View health monitoring. The most common types of health monitoring are ICMP and HTTP.
HTTP health monitors are optional in a VMware View deployment, however strongly recommended. The Load Balancer appliances issue a GET URL command to retrieve the index.html page from each connection broker in the pool.
When the Load Balancers probe a Security Server, the Security Server immediately performs a check against the Connection Server for which it is configured. This check between the Security Server and Connection Server happens over the AJP13 (TCP 8009) connection.
Monitoring VMware View Web Services
| VMware View Manager Server Service Port | User port – 443 |
| VMware View Manager Server Windows Service | VMware View Connection Server Service(s) |
| VMware View Web Administration | Server/admin |
In addition to HTTP health there are other VMware View services and ports that can be monitored.
Monitoring Desktop vCenter Server service
| Java Message Bus Port | <viewmanagerserver>.CUSTOMER.com:4001 |
| JMS Routing Port | <viewmanagerserver >.CUSTOMER.com:4100 |
| Server Windows Service | VMware View Connection Server Service |
| Directory Service Port | <viewmanagerserver >.CUSTOMER.com:389 |
| VMware Virtual Desktop Manager Directory Service | VMware VDMDS Service |
| VMware vCenter Server Service Port | From each View Manager Server eg: <viewmanagerserver>.CUSTOMER.com:443 |
| VMware vCenter Server Service | VMware vCenter Server Service |
VMware View Manager Server/Active Directory connectivity
VMware View uses Active Directory to authenticate users for access to desktops. VMware View Web Administrator also queries Active Directory in order to entitle users and groups to desktop pools. Active Directory should be accessible from the View Manager Servers and can also be monitored.
| Active Directory for VMware View | AD.CUSTOMER.com:389From each View Manager Server |

Hi Andre, first thanks for the mention of my post.
I was looking for some static content to download in order to better check the status of Connection Server, and your suggestion about index.html is great!
I was first confused since via web browser asking for index.html gave me a 404 error, but via curl the index.html is retrieved.
I’ve added an additional line to my haproxy configuration to perform this check.
Thanks,
Luca.
