Dotnet Build Metrics

This is a custom MSBuild task that will measure the time to build each project and publishes the information to a datastore. The intent is to measure and improve developer experience on local workstations.

Username and hostname are collected as a part of build information

{
    "id": "026fe42b-7888-4a76-81ee-2ab431ae4987",
    "userName": "aanand",
    "cpuCount": 12,
    "hostname": "25BVM13",
    "platform": 2,
    "os": "Microsoft Windows NT 10.0.19042.0",
    "timeTaken": "453",
    "branch": "master",
    "type": ".Net",
    "projectName": "Agoda.Cronos.Accommodation",
    "repository": "[email protected]:front-end/dotnet-build-metrics.git",
    "date": "2021-06-28T02:53:22.1420552Z"
}

To use the task simply install the Agoda.Builds.Metrics NuGet package to all of the projects in your solution, this will automatically enable metrics publication for that project.

Web API URL and the name of the endpoint are taken from environment variables if they are present as per the following table:

Parameter	Environment Variable	Default Value
Elastic Search Endpoint	BUILD_METRICS_ES_ENDPOINT	http://compilation-metrics/dotnet

We recommend create a CNAME on your internal DNS servers for compilation-metrics to point at an internal API that captures the data and stores it.

Example build log output in Visual Studio using MSBuild.

Example build log output in Dotnet core CLI.

Agoda.DevFeedback.AspNetStartup NuGet package

The goal of this package is to measure the application startup time as an additional metrics that affects developer feedback besides build time. Monoliths are especially prone to slow startup times on developer laptops and this provides visibility and tracking of improvements/regressions thereof.

This package measures the ASP.NET application's startup time in two ways.

1. The time from WebHostBuilder ConfigureServices until HostApplicationLifetime OnStarted sent with type '.AspNetStartup'.
2. The time from WebHostBuilder ConfigureServices until the first HTTP Reponse (measured from middleware) sent with type '.AspNetResponse'.

Two environment variables are required to be set to enable the measurements.

1. ASPNETCORE_ENVIRONMENT needs to be set as Development for the functionality to be added. This is so it's only enabled locally and not on production.
2. ASPNETCORE_HOSTINGSTARTUPASSEMBLIES needs to be/include Agoda.DevFeedback.AspNetStartup. This is for package activation due to the use of HostingStartup.

For convenience these environment variables can be set under the lauch profile of the web application's launchSettings.json file and committed to the repository.
