DotNet Core NewRelic Integration

-

Prerequisites

  • docker
  • vscode
  • vscode plugin: Docker
  • already have created a dotnet core application
  • already have a Dockerfile

Add the newrelic agent to the docker image

Add these sections to your Dockerfile, directly after the FROM base AS final.

Install the agent

RUN apt-get update && apt-get install -y wget ca-certificates gnupg \
&& echo 'deb http://apt.newrelic.com/debian/ newrelic non-free' | tee /etc/apt/sources.list.d/newrelic.list \
&& wget https://download.newrelic.com/548C16BF.gpg \
&& apt-key add 548C16BF.gpg \
&& apt-get update \
&& apt-get install -y newrelic-netcore20-agent

Enable the Nuget agent

ENV CORECLR_ENABLE_PROFILING=1 \
CORECLR_PROFILER={36032161-FFC0-4B61-B559-F6C5D41BAE5A} \
CORECLR_NEWRELIC_HOME=/usr/local/newrelic-netcore20-agent \
CORECLR_PROFILER_PATH=/usr/local/newrelic-netcore20-agent/libNewRelicProfiler.so \
NEW_RELIC_LICENSE_KEY=REPLACE_THIS_WITH_YOUR_NEWRELIC_LICENCE_KEY \
NEW_RELIC_APP_NAME='REPLACE THIS WITH YOUR APPLICATION NAME'

Test

Build and run your docker image using terminal or the vscode Docker plugin.

Load up your web-api and hit an endpoint. It takes a minute or so for the logs to be sent to NewRelic’s servers and to appear in your charts.

Taking a memory dump of a w3wp process

Taking a memory dump of a w3wp process Taking a memory dump of an IIS worker process in a live system can be problematic, as IIS will kill the process if it has been suspended for more than 60 seconds. Only use these steps if your application is on a high availability cluster, else you’ll take your app down! copy sysinternals procdump.exe and pssuspend.exe to target machine create powershell file with: $iispid = Get-Process svchost | ? { $_ . modules . ModuleName -eq "iisw3adm.dll" } | Select - First 1 - ExpandProperty Id $workerpid = Get-Process w3wp | Sort ws - Descending | Select - First 1 - ExpandProperty Id & ".\pssuspend.exe" $iispid Write-Output "Creating memory dump for w3wp PID $workerpid " & ".\procdump.exe" - ma $workerpid & ".\pssuspend.exe" $iispid - r (taken from stackoverflow ) 3) check the w3wp process has reached the high level of RAM usage that you’re intending to

GitLab Badges

GitLab has built in functionality to allow you to add badges, to provide an at-a-glance status of your app's quality.  In order to set project badges up, you need to be a maintainer of the project so that you can access the settings. Pipeline Status This shows whether your master branch pipeline has passed or failed.  The badge is super easy to set up.  In GitLab go to Settings > General > Badges > Add Badge, and enter this: Name:  Pipeline Link:  https://gitlab.com/%{project_path}/commits/%{default_branch} Badge: https://gitlab.com/%{project_path}/badges/%{default_branch}/pipeline.svg These links should be right for any project, as they're using variables. Coverage % Code coverage is a little more involved, as it relies on you having already configured code coverage in your app.  For the app I've been working on, which is a dotnet application, I opted to use the opensource MiniCover .  This is configured to writes a code coverage report to the

sp_blitzIndex

Some more notes after watching Brent’s How I Use the First Responder Kit: sp BlitzIndex . This sproc will analyse every index across all databases in your sql server and return a prioritised list of potential issues. EXEC sp_blitzIndex @GetAllDatabases = 1 The MoreInfo column is interesting. If you copy the SQL out and run it, it will give you more information on the indexing issue in question. E.g: EXEC dbo . sp_BlitzIndex @DatabaseName = 'YourDatabase' , @SchemaName = 'dbo' , @TableName = 'tFoo' ; If you run this, the top result set it a list of indexes that are on the target table. It shows how many seeks and scans each index has had, the size of the index, etc. Note the URL column for more information on each issue category. Missing indexes are shown in the 2nd result set. The 3rd result set shows the table definition, which is nice to have without having to mess with the SSMS UI.
