July 25, 2019

Enhancements

  • This release brings the .NET Agent for Linux closer to parity with the .NET Agent for Windows by providing a feature preview for HTTP backend detection and naming using Custom HTTP Discovery Rules. Configure the .NET Agent for Linux to detect HTTP backends using URI segments, instead of detecting and naming the backend using the default autodiscovery rules that identify the backend based solely on the Host and Port. Using Custom HTTP Discovery rules is especially useful to detect and name HTTP backends behind an API gateway or portal. Defining the HTTP backend based on the URL segments in the Custom HTTP Discovery rule enables AppDynamics to resolve the HTTP backends to tiers properly, giving you accurate metrics for your API services. See HTTP Backend Detection and .NET Backend Detection

    Note
    There is a known issue in HTTP backend detection configuration in the current preview. When defining HTTP backend using URL segments, segment enumeration starts with number 2 instead of number 1, and segment 1 always returns empty. For example, to define unique backends using the first two segments of the URL, you would need to configure HTTP backend detection to use the first 3 segments or segment 2 and 3.
  • The .NET Agent for Linux now collects and displays error metrics for exceptions handled using either the ASP.NET Core exception handler page or exception handler lambda.

Version 4.5.8.0 – February 22, 2019

Enhancements
  • You can analyze data collected from the .NET Agent for Linux, and create business monitoring dashboards to better understand your .NET Core applications with Transaction Analytics.
  • AppDynamics now automatically detects and monitors backend calls to Redis using the stackexchange library on .NET Core for Linux.
  • The .NET Agent supports IIS in-process hosting for ASP.NET Core 2.2. This enables you to monitor your .NET Core applications running on the latest .NET Core release, whether they are running in Azure or on-premise. 

...

Version 4.5.7.0 – January 29, 2019

Enhancements
  • AppDynamics .NET Agent for Linux allows you to monitor your performance of .NET Core applications in production running on Linux OS, so you get real-time visibility of application performance, business transactions, and resource metrics. The .NET Agent for Linux is available on AppDynamics Controller version 4.4.1+. The supported environments are constantly being updated. See .NET Agent for Linux for more information.

...

Version 4.5.6.0 – December 20, 2018

Enhancements
  • Controller and Agent environment variables now follow the standard underscore naming format. There are also two new variables APPDYNAMICS_CONTROLLER_SSL_CERTFILE and APPDYNAMICS_CONTROLLER_SSL_CERTDIR. See .Net Agent Configuration Properties for more information.
  • The .NET Agent supports functionality to reference any environment variables when configuring Agent Node Name, Agent Tier Name, or Controller Application Name. This should help when deployment slots are enabled in Azure App Services. You can monitor and analyze performance metrics from different deployment slots by using node names. See .NET Agent Environment Variables for more information.
