Version 4.5.13 - July 25, 2019
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.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 4.5.11 – May 16, 2019
The .NET Agent and .NET SDK for Linux now support proxy access to the Controller. You can configure the proxy in the
AppDynamicsConfig.json file or by defining the relevant environment variables. See .NET Agent for Linux Environment Variables, .NET Agent for Linux Advanced Configuration Options, and Using .NET Core for Linux SDK.
|DOTNET-3485||POCO business transactions are not identified in Azure Service Fabric app|
Version 4.5.10 – April 22, 2019
The .NET Agent in its default configuration now monitors virtual applications running inside Azure Web Apps. See Monitor Virtual Applications of Azure Web Apps and 'Specify Which WebJobs to Monitor' in Install the AppDynamics Azure Site Extension for .NET.
Improved visibility of asynchronous task-based transactions.
|DOTNET-3596||.NET Microservices Agent may cause exception for applications using SQL Reporting Services Report Viewer control.|
Version 4.5.9 – March 29, 2019
- Edging towards the goal of parity with the .NET Agent for Windows, in this release, the .NET Agent for Linux provides improvements to business transaction detection, configuration, and naming. In the Controller UI you can limit the transactions monitored by choosing to include or exclude ASP.NET and POCO business transactions matching criteria you specify. See .NET Agent Business Transaction Configuration
The ability to customize Business Transaction detection that is now supported by .NET Agent for Linux version 4.5.9 requires Controller versions 4.5.2 and higher. The .NET Agent for Linux version 4.5.9 works with Controller version 4.4.1 and higher, but the customizable transaction detection and configuration capabilities require 4.5.2 and later versions of the Controller. See Agent and Controller Compatibility.
For Controller versions 4.4.2 to 4.5.1 and the .NET Agent for Linux, AppDynamics defaults to use two segments for ASP.NET business transaction naming.
|DOTNET-3675||Windows service application is crashing with AppDynamics NLog call stack.|
Version 126.96.36.199 – February 22, 2019
- 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.
|DOTNET‑3224||Identify REDIS backends using host name rather than server name, as server name changes frequently. Prevents backend explosion|
|DOTNET‑3436||Slow memory leak affecting Full and Microservice .NET Agents|

Version 188.8.131.52 – January 29, 2019
- 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.
- The .NET Agent for Linux supports reuse node name configuration to help manage monitoring environments where there are many CLRs with short life spans. See .NET for Linux Advanced Configuration Options for more information.
- The Agent also supports naming MVC transactions by area, Controller, and action. See Name MVC Transactions by Area, Controller, and Action for more information.

- 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.
