.NET Beta SDK Instrumentation

Please note that .NET SDK support is currently in Beta phase and we offer limited support to limited customers

This page will dive into the nitty gritty details on installing Rookout under various configurations.
If you are encountering any difficulties with deploying Rookout, this is the place to look.

.NET

The .NET SDK provides the ability to fetch debug data from a running application in real time.

Setup

NuGet Package

Rookout SDK is installed as a NuGet package in your application.

API

The Rookout SDK needs to be started using a simple API.

using Rook;
namespace Program
{
    class Program
    {
        static int Main(string[] args)
        {
            Rook.RookOptions options = new Rook.RookOptions() 
            {
                token = "[Your Rookout Token]",
                labels = new Dictionary<string, string> { { "env", "dev" } }
            };
            Rook.API.Start(options);
    
            // ...
        }
    }
}

SDK API

The .NET SDK is loaded via an API.
Configuration may be passed through the API or using OS Environment Variables.

start

public static void Start(RookOptions opts)

The Start method is used to initialize the SDK in the background and accepts the RookOptions object with the following attributes:

Argument	Environment Variable	Default Value	Description
`token`	`ROOKOUT_TOKEN`	None	The Rookout token for your organization. Should be left empty if you are using a Rookout ETL Controller
`labels`	`ROOKOUT_LABELS`	{}	A dictionary of key:value labels for your application instances. Use `k:v,k:v` format for environment variables
`host`	`ROOKOUT_CONTROLLER_HOST`	None	If you are using a Rookout ETL Controller, this is the hostname for it
`port`	`ROOKOUT_CONTROLLER_PORT`	None	If you are using a Rookout ETL Controller, this is the port for it
`proxy`	`ROOKOUT_PROXY`	None	URL to proxy server
`debug`	`ROOKOUT_DEBUG`	False	Set to `True` to increase log level to debug
`log_file`	`ROOKOUT_LOG_FILE`	None	Path to file to use for the SDK logs (default is `%USERPROFILE%/rookout/dotnet-rook.log`)
`log_level`	`ROOKOUT_LOG_LEVEL`	None	Control the SDK logging verbosity
`log_to_stderr`	`ROOKOUT_LOG_TO_STDERR`	False	Set to `True` to have the SDK log to stderr
`git_commit`	`ROOKOUT_COMMIT`	None	String that indicates your git commit
`git_origin`	`ROOKOUT_REMOTE_ORIGIN`	None	String that indicates your git remote origin

Test connectivity

To make sure the SDK was properly installed and test your configuration (environment variables only), download and run TestConnectivity:

Windows .Net Framework
Windows .Net Core
Ubuntu .Net Core
Mac .Net Core - Use right click and open to allow the tool to run

Debug Information

Rookout requires your application to be deployed with debug information (Pdb files <DebugType>pdbonly</DebugType> or -debug+) and the optimize flag should not be enabled (<Optimize>false</Optimize>)

Pdb (Program Data Base) file is a repository to maintain information about your application.

It stores the important debug information such as:

file names
variable names
offsets of the functions
file hashes

Although Rookout doesn't run your program in debug mode, we need the PDB file to properly collect the data per your request.
