Getting started with EasyHA Client

EasyHA system/application monitoring tools has web front end. You can manipulate the application via web browser like MS-IE, Chrome and Firefox. I think you want to view status of EasyHA by rich client on Windows or mobile APP on your smart phone. In this post I would like to introduce the EasyHA Client for Windows desktop.

EasyHA Client application is available for Windows platform only till now. It is a Win32 GUI application. It runs in client/server mode. It connects to EasyHA server, and retrieve the status of the server. In case trigger is fired, you will receive the information of the event in time, and the EasyHA Client will deliver notifications using balloon tips or flashing tray icon. So you don’t need to check the web front end, and if you are using windows desktop, you will be aware of the event/note soon.

Installing and uninstalling

Download and run the installer which will walk you through the process. To uninstall the client on Windows run the uninstall.exe in installation directory.

Settings

As EasyHA Client runs in client mode, we should please specify the EasyHA server host name, port number. To verify the user’s credential, you should also specify the user name and password. The information will be remembered for next time you run the client.

The communication between EasyHA Client and Server is one way (from the client to server) and http based, so normally there shouldn’t be problem with firewalls. Of course, the access through the given port should be allowed by your network administrator.

Please click File -> Setting/Login menu, and you will see the settings dialog.
