uberAgent 5.2: Firefox Browser Performance & Citrix ADC Monitoring

  • by Dominik Britz
  • February 4, 2019

We are happy to announce the newest version of our user experience and application performance monitoring product. uberAgent 5.2 brings new features and improvements for any kind of device.

For a full list of all improvements and bugfixes please consult the changelog. As always, upgrading is highly recommended (instructions).

Dashboard Citrix ADC Appliance Performance

Web App Metrics From Mozilla Firefox

In version 5.0 we added detailed information about browser page loads and background data transfers. Exactly what you need to analyze the performance of SaaS and web apps.

Our customers loved this feature! We started with support for Chrome, then Internet Explorer and are now extending this to Mozilla Firefox (support for Edge to follow). The functionality requires a browser extension to be installed.

Citrix ADC Monitoring

uberAgent has had Citrix site monitoring capabilities for a long time. With 5.2, we are extending our Citrix monitoring portfolio to Citrix ADC (formerly NetScaler ADC). Citrix ADC is a critical component in every Citrix deployment as it provides a secure gateway to published resources from all over the world. As it is such an important component, administrators need to know if it is fast, secure and configured correctly.

uberAgent delivers right that by monitoring:

  • Citrix ADC appliance performance like CPU, RAM and disk utilization
  • Citrix ADC gateway and virtual server performance like network data volume, SSL settings, bound policies and availability
  • Availability for services and service groups

In addition, uberAgent collects inventory data from all Citrix ADCs and shows you licensing, high-availability and firmware information as well as TLS certificates with their expiration dates.

Instructions on how to configure uberAgent’s Citrix ADC monitoring can be found here.

Other Improvements

Apache Kafka

With uberAgent 5.2 we introduce the ability to send the collected data to Apache Kafka via Confluent REST Proxy. Instructions are available in the documentation.

Data Models

We separated the inventory datasets into a dedicated uberAgent60m accelerated data model, with the summarization period set to 60 minutes. This helps reduce the Splunk server load.


As more and more of our customers start using Microsoft’s Azure Active Directory, we added the ability to cover this service within our licensing.

Log File Improvements

uberAgent’s logfile now highlights version mismatches between the agent and the configuration file. This is intended as a reminder to enable additional metrics introduced in a newer version that a customer configuration does not cover.

I would not worry about supporting Edge Microsoft is moving to a chromium based browser. (ref.

How do you plan on monitoring AJAX based sites that do not load new tabs often? E.g.

Thanks, we are quite aware of Edge switching to Chromium and very happy about it. It means that our existing Chrome extension will work in Edge, too.

Regarding AJAX monitoring: we track XmlHttpRequest duration, too, in addition to page load duration (documentation).

Is there some functionality that you are missing?
