Monitoring Virtual League Submission

CloudWatch Log Dashboard

By using CloudWatch Log Insights, we can create a dashboard to show the racing time of every submission, grouped by race type

Warning: AWS allow up to 3 free dashboard, if you exceed this limit, each extra dashboard cost you $3 per month

Setup Steps

1. Go to https://console.aws.amazon.com/cloudwatch/home?region=us-east-1#dashboards:
2. Click "Create Dashboard", give the dashboard a name (e.g. DeepRacer Results), click "Create dashboard"
3. Close out any popups
4. Click "Action" > "View/edit source"
5. Replace the source with the following code, then click "Update"

In Community Slack we are usually running two or three league channels:

• #league-public - lists top ten leaders of an ongoing race and (during the season) best-effort calculation of cumulative results from races so far
• #league-community - lists how community members are doing against each other
• #league-contest - shows the ranking of community contests when they are ongoing
