Getting started with the vCSA 6.x – Part 2

30/07/2017

In the previous post we started to unravel the vCSA and discussed topics like the Appliance shell, the file system and the services. In this post we will continue with the vCSA Health.

Health

Knowing the health of your system is important. Like the Windows vCenter Server, the vCSA is also able to report its health. Most common is using the vSphere Web Client and from the main menu, choose: System Configuration and watch the “Service Health” pane. Detailed information can be found by clicking on the various Services.

However, from the Appliance shell, the following API command will also inform you”

Command> system.health.get

If everything is OK, it will report; Health: green

In the Bash shell, you can browse to the folder: /etc/vmware-sca/health/.
On a vCSA 6.0, you will find two files with health status information:

vmware-vpxd-health-status.xml
vmware-postgres-health-status.xml

But now the vCenter Server Appliance (vCSA) is the new and preferred standard. The vCSA comes as a virtual appliance and is ready to run within minutes compared to the old vCenter Server. Although a (virtual) appliance still means; (virtual) hardware, an operating system, middleware and applications, VMware likes to treat the vCSA as a “black box”. Like most appliances, the operating system is a Linux flavor and you can log in. After a successful log in, you will encounter the first discouragement; you are not welcomed by a Bash shell but with the default “Appliance Shell”. For more information read my post on the vCSA shells.
In this post, a brief introduction on the following topics; Appliance shell, File system and the Services.
