Configuration on ASP.NET
editConfiguration on ASP.NET
editWhen monitoring ASP.NET applications the agent uses two sources of configuration:
-
web.config
<appSettings>
section - Environment variables
web.config takes precedence over environment variables which means that the agent tries first to find a configuration option value by its key in web.config. If it’s not present, then the agent tries to look for it among environment variables. If it’s not present, the agent falls back to the options default value.
You can find the key of each configuration option
in the IConfiguration or web.config key
column of the corresponding option’s description.
Sample configuration file
editBelow is a sample web.config
configuration file for a ASP.NET application.
<?xml version="1.0" encoding="utf-8"?> <!-- ... --> <configuration> <!-- ... --> <appSettings> <!-- ... --> <add key="ElasticApm:ServerUrl" value="https://my-apm-server:8200" /> <add key="ElasticApm:SecretToken" value="apm-server-secret-token" /> <!-- ... --> </appSettings> <!-- ... --> </configuration>
Additionally, on ASP.NET, you can implement your own configuration reader. To do this, implement the IConfigurationReader
interface from the Elastic.Apm.Config
namespace.
Once implemented, you can use the FullFrameworkConfigurationReaderType
setting.
FullFrameworkConfigurationReaderType
editThis setting is .NET Full Framework only.
This setting can point an agent to a custom IConfigurationReader
implementation and the agent will read configuration from your IConfigurationReader
implementation.
Use type name in AssemblyQualifiedName format (e.g: MyClass, MyNamespace
).
Environment variable name | web.config key |
---|---|
|
|
Default | Type |
---|---|
None |
String |
If this setting is set in both the web.config file and as an environment variable, then the web.config file has precedence.
