Datadog Fundamentals
In Datadog, this is the primary way to slice and filter telemetry with key:value pairs (like service:checkout)
Tags
The Datadog log concept that lets you keep only a portion of logs while still retaining visibility
Logging Without Limits
Users are reporting that the 'Check Out' button is broken on mobile, but our backend metrics look green.
What is Real User Monitoring (RUM)?
We need to know if an S3 bucket was accidentally made 'public' in our AWS account.
What is Cloud Security Management (CSM)
The lightweight process that runs on your servers to collect and send data to Datadog
Datadog Agent
The Datadog feature that lets you graph metrics over time and combine queries into a single view.
Dashboards
In Datadog, this turns log events into time-series counts you can alert on (e.g., 5xx errors per minute).
Log-based Metrics
"We want to simulate a user login flow every 5 minutes from Paris, Tokyo, and New York."
What is Synthetics Browser Tests
I need a way to detect and look for specific patterns like 'Password123' or Credit Card numbers in our logs and other telemetry
What is Sensitive Data Scanner
We are moving to Google Cloud Run Functions and Azure App Services and need to monitor functions that only live for 2 seconds
What is Serverless Monitoring?
The Datadog feature that turns raw events into actionable notifications with thresholds, schedules, and routing
What is a monitor?
This Datadog Logs feature helps group similar log lines and highlights emerging errors in a click of a button.
Log Patterns
This feature allows us to see the exact line of code causing a bottleneck in a Java or Python application.
What is Continuous Profiler?
We need to automatically identify which of our production services are using open-source libraries with known critical vulnerabilities (CVEs).
What is Code Security - Software Composition Analysis (SCA)
The feature that provides a 'bird's eye view' of all your containers, colored by health or resource usage
What is a Container Map?
The practice of keeping cardinality under control by avoiding high-uniqueness values (like user IDs)
High Cardinality
The Datadog mechanism that ties logs to traces so you can jump from a slow request span directly to relevant log lines.
Log-Trace Correlation
The Datadog capability that automatically surfaces the 'root cause' (e.g., a specific deployment or database query) during an issue
What is Watchdog AI
This feature monitors at the kernel level to detect if a suspicious process like a crypto-miner or an unauthorized shell is executed on a production host.
This tool identifies 'orphaned' cloud resources (like unattached EBS volumes) to help save money.
What is Cloud Cost Management?
Datadog’s mechanism for keeping related telemetry together by automatically attaching metadata such as: service, env, and version.
Unified Service Tagging
Which two mechanisms allow you to achieve Log-Trace correlation?
Trace ID + Span ID
We need to ensure our third-party APIs (like Stripe or Twilio) are responding within 200ms."
What is Synthetics API Tests
Detecting a SQL injection attempt or a Cross-Site Scripting (XSS) attack in real-time.
What is App & API Protection (AAP)
The specialized Datadog Agent used specifically to reduce API calls in a Kubernetes environment
The Cluster Agent
