Citrix Netscaler ADC extension

Latest Dynatrace
Extension
Published Oct 27, 2025

Monitor your Citrix NetScaler devices remotely.

Get started

Overview

Monitor Citrix NetScaler via ActiveGate extension to enhance security and virtualization visibility.

Citrix NetScaler ADCs help enterprises secure applications and data. However, they do not permit the installation of agent-based monitoring solutions. For this, Dynatrace offers remote monitoring of NetScaler devices via the Citrix NetScaler ActiveGate extension. Our extension queries devices every minute and retrieves key performance data. These metrics are paired with OneAgent data to provide real-time interaction visualization and the ability to follow transactions throughout your stack.

Use cases

Monitor the health and performance of their NetScaler services.
Monitor NetScaler with a dedicated dashboard and Dynatrace entities to represent core components.
Detect and alert on anomalies.

Compatibility information

Feature sets

When activating your extension using monitoring configuration, you can limit monitoring to one of the feature sets. To work properly, the extension has to collect at least one metric after the activation.

In highly segmented networks, feature sets can reflect the segments of your environment. Then, when you create a monitoring configuration, you can select a feature set and a corresponding ActiveGate group that can connect to this particular segment.

All metrics that aren't categorized into any feature set are considered to be the default and are always reported.

A metric inherits the feature set of a subgroup, which in turn inherits the feature set of a group. Also, the feature set defined on the metric level overrides the feature set defined on the subgroup level, which in turn overrides the feature set defined on the group level.
