Add "Watchtower" section to "Monitor Applications and Infrastructure with Datadog"

[acrollet]

Description

As part of the code yellow effort, we need to update the monitoring documentation to add a section explaining required monitors and watchtower integration for VA.gov applications.

Proposed content

Watchtower integration

Required monitors

All VA.gov apps must have the following core monitors with appropriate alerts configured:

• Error rate
• Anomalies
• Queue exhaustion (If the app does background processing)

Each core monitor should have the "watchtower" tag, and be tagged with the priority corresponding to its app’s tier.

App tier guidance

Daily transactions/page views	Learn about	View benefits	Use/manage benefits	Apply for benefits
10,000+	tier 1	tier 1	tier 1	tier 1
1,000+	tier 2	tier 2	tier 1	tier 1
100+	tier 3	tier 3	tier 2	tier 1
0+	tier 3	tier 3	tier 2	tier 2

Follow the above chart to determine your app’s tier. Your app’s tier classification should be reviewed periodically and when functionality or usage changes significantly.

Category examples
