Network Visibility Requirements and Supported Environments
Please review the following guidelines and notes before you enable Network Visibility.
Network Visibility requires a supported version of the Network Agent to be installed on the monitored server.
Network Visibility features are available for Linux and Windows. You need a Network Visibility license to enable and use Network Visibility features. Network Visibility is enabled by default on AppDynamics controllers. For more information, see License Entitlements and Restrictions.
Linux System Requirements
Network Visibility requires:
- Controller version 4.4 or higher with a Network Visibility license.
- You must have
rootaccess permissions on the agent host to install the Network Agent. You do not need
rootaccess to run the agent.
- Each host on Linux must have
- A Network Visibility Agent (version 4.4 or higher)
- A Java App Server agent (version 4.4 or higher) with an App Agent license
- Network Visibility is supported on Linux hosts with Java App Server Agents only.
Network Visibility on Linux
The Network Agent is supported on Linux distributions based on glibc 2.12 or higher:
- CentOS 6 and higher (32-bit and 64-bit)
- Ubuntu 14 and higher (32-bit and 64-bit)
- Red Hat Enterprise Linux 6 and higher (32-bit and 64-bit)
- Fedora 24 and higher (32-bit and 64-bit)
The Network Agent host must have the following libraries pre-installed:
Windows System Requirements
Each Windows host must have:
- A .NET Agent, version 4.5.15 or later, with an App Agent License. See Install the .NET agent and License Management.
- A Controller, version 4.5.14 or later, compatible with the .NET Agent.
- A Java Agent, version 18.104.22.16886 or later, with an App Agent license. See Install the Java Agent and License Management.
- A Controller, version 22.214.171.12486 or later, compatible with the Java Agent. See Agent and Controller Compatibility. Installing AppDynamics to test or evaluate, typically involves verifying system requirements, preparing the host, and then performing the Controller installation. See Install the Controller Using the Enterprise Console and Install the Controller Using the CLI.
- The Network Visibility Agent. Download the Network Agent version 4.5.7 or higher.
- An account with administrative privileges on the Windows machine where you want to install the Network Agent.
Network Visibility on Windows
The Network Agent is supported for Java applications on these Windows distributions:
- Windows Server 2019 (64-bit)
- Windows Server 2016 (64-bit)
- Windows Server 2012 (64-bit)
- Windows Server 2012 R2 (64-bit)
- Windows Server 2008 (64-bit)
- Windows Server 2008 R2 (64-bit)
The Network Agent is supported for .NET applications running on Windows starting with .NET Framework version 3.5 on the following runtime environments:
- Microsoft IIS versions 6.0, 7.0, 7.5, 8.0, 8.5, 10
- Managed Windows Services
- Managed Standalone Applications
You can use the Network Visibility features with .NET agent if you have installed:
- Network Agent version 4.5.7 or higher
- .NET agent version 4.5.15 or higher
- AppDynamics controller version 4.5.14 or higher
You can monitor .NET applications that are implemented using synchronous calls. However, Directory Search and ADO.NET are not supported.
Network Visibility is not enabled by default. You can enable it by setting the agent node property
socket-enabled=true. For information on setting this property, see App Agent Node Properties (S).
AppDynamics does not currently support monitoring network traffic for asynchronous .NET calls.
- This release does not support the following Network Flow Map features:
- Federated Flow Maps
- Visualization of flows between web servers and APM entry tiers
- The Network Flow Map does not filter out connections based on the selected time range.
The Network Agent cannot monitor multiple App Server Agents on the same host if these agents report to different Controllers. All App Server Agents must report to the same Controller.
The Network Dashboard does not show data for Health Rules.
You cannot view Health Rule violations in the Network Dashboard. To view any Health Rule violations, including those based on Network Visibility data, go to the Application Dashboard.
- If you open the Network Flow Map for an individual node, the KPI metrics for node-to-load-balancer and node-to-TCP-endpoint links show network KPIs for all nodes in the parent tier (instead of KPIs for the individual node only). To view KPIs for the individual node, open the link popup and look at the Connection KPIs.
Network Visibility cannot monitor Cross Application Flows that use Jersey web servlets. As a workaround, you can disable Jersey servlet instrumentation. The impact is that Business Transactions on these flows get recognized as servlets instead of Web Services. To implement this workaround:
- Select the application of interest in the Controller UI.
- Choose Configuration > Instrumentation > Transaction Detection.
- Disable instrumentation for Jersey Servlet and Jersey 2.x Servlet
