Citrix OnPrem VDI

Introduction

Citrix VDI are virtualization solutions that give IT control of virtual machines, applications, licensing, and security while providing access for any device.

Citrix Virtual Applications and Desktops allow:

End users to run applications and desktops independently of the device’s operating system and interface.
Administrators to manage the network and control access from selected devices or all devices.
Administrators to manage an entire network from a single data center.

Citrix Virtual Applications and Desktops share a unified architecture called FlexCast Management Architecture (FMA). FMA’s key feature is to run multiple versions of Citrix Virtual Applications or Citrix Virtual Desktops from a single site and integrated provisioning.

Prerequisites

The OpsRamp Gateway must be installed.

Configure and install the integration

Go to Setup > Integrations and Apps.
Click + ADD on the INSTALLED APP page. The ADD APP page displays all the available applications along with the newly created application with the version.
Notes:
- If there are already installed applications, it will redirect to the INSTALLED APPS page, where all the installed applications are displayed.
- If there are no installed applications, it will navigate to the ADD APP page.
- You can even search for the application using the search option available. Also you can use the All Categories option to search.

Click ADD in the Citrix OnPrem VDI application.
In the Configurations page, click + ADD. The Add Configuration page appears.
Enter the below mentioned BASIC INFORMATION:


Functionality	Description
Name	Enter the name for the configuration.
Host Name / IP Address	Host name / IP address of the target
Port	Port Note: By default 80 is added.

Risks, Limitations & Assumptions

Application can handle Critical/Recovery failure notifications for below two cases when user enables App Failure Notifications in configuration:
- Connectivity Exception (ConnectTimeoutException, HttpHostConnectException, UnknownHostException)
- Authentication Exception(UnauthorizedException)
Application will not send any duplicate/repeat failure alert notification until the already existed critical alert is recovered.
Application cannot control monitoring pause/resume actions based on above alerts.
Metrics can be used to monitor Citrix resources and can generate alerts based on the threshold values.
No support of showing activity log and applied time.
No support for the option to get Latest snapshot metric.
