Getting Started
What You Need
To start using anomaly detection in Datadog, you'll need:
- A Datadog account with the right permissions to set up anomaly detection. This usually means having admin access or a role that allows configuring anomaly detection.
- Data sources set up to send data to Datadog. This could be application logs, metrics, traces, or other data sources.
Setting Up Data Collection
Before you can use anomaly detection, you need to get your data into Datadog. Here's how:
- Identify the data sources you want to monitor, like application logs, metrics, or traces.
- Set up Datadog to collect data from those sources. You can use built-in integrations or APIs.
- Check that the data is flowing into Datadog correctly.
Once your data is in Datadog, you're ready to configure anomaly detection.
| Step | Description |
|---|---|
| 1. Identify Data Sources | Decide what data you want to monitor, like logs, metrics, or traces. |
| 2. Set Up Data Collection | Use Datadog integrations or APIs to start sending data to Datadog. |
| 3. Verify Data Flow | Make sure the data is arriving in Datadog as expected. |
Configuring Anomaly Detection
Setting up anomaly detection in Datadog is a straightforward process. Here's how to enable and configure it, choose the right algorithm, and set the necessary parameters.
Step-by-Step Setup
Follow these simple steps to configure anomaly detection:
- Go to the Datadog query editor and select the metric you want to monitor for anomalies.
- Click the "Functions" dropdown and choose "Anomaly Detection."
- Pick the algorithm you want to use (more on this below).
- Set the bounds for the algorithm (we'll explain this later).
- Click "Apply" to save your changes.
Choosing an Algorithm
Datadog offers three anomaly detection algorithms, each suited for different types of metrics:
| Algorithm | Description |
|---|---|
| Basic | Uses a simple rolling quantile calculation to determine the expected value range. It adjusts quickly to changes but doesn't account for seasonality or long-term trends. |
| Agile | A robust version of the SARIMA algorithm. It's sensitive to seasonality and can quickly adjust to level shifts in the metric. |
| Robust | A seasonal-trend decomposition algorithm that works best for seasonal metrics with a relatively level baseline. Its predictions are very stable, so long-lasting anomalies won't unduly influence the forecast. |
For metrics with daily or weekly fluctuation patterns, we recommend starting with the agile or robust algorithm.
Setting Parameters
When configuring anomaly detection, you'll need to set the bounds for the algorithm. The bounds determine the tolerance of the anomaly detection algorithm and the width of the "normal" gray band.
Think of these bounds as deviations from the predicted timeseries value. For most timeseries, setting the bounds to 2 or 3 will capture most "normal" points in the gray band.
Creating Anomaly Monitors
Anomaly monitors help you track and respond to unusual behavior in your applications and infrastructure. They allow you to detect potential issues before they impact users.
Why Use Monitors
Monitors enable you to:
- Identify anomalies in real-time, minimizing downtime
- Spot trends and patterns in your data for better decision-making
- Receive timely alerts, ensuring prompt action
Setting Up Monitors
To create an anomaly monitor in Datadog:
- Go to the query editor and select the metric to monitor.
- Click "Functions" and choose "Anomaly Detection."
- Pick the algorithm (Basic, Agile, or Robust).
- Set the algorithm bounds (e.g., 2 or 3).
- Click "Apply" to save.
- Configure alert conditions and notifications.
| Step | Action |
|---|---|
| 1 | Select the metric to monitor |
| 2 | Choose "Anomaly Detection" |
| 3 | Pick the algorithm |
| 4 | Set the algorithm bounds |
| 5 | Save changes |
| 6 | Configure alerts and notifications |
Alert Conditions
When setting up alerts, you can:
- Trigger alerts when the metric exceeds or falls below the expected range
- Define warning and recovery thresholds
Notification Setup
To ensure timely alerts, you can:
- Set up email notifications or integrate with tools like Slack or PagerDuty
- Define notification frequencies and escalation procedures
- Customize notification content for relevant context
Visualizing Anomalies
Seeing anomalies clearly is key to understanding and responding to unusual behavior in your applications and systems. In Datadog, you can add anomaly detection to existing graphs and dashboards, giving you a clear view of potential issues.
Adding to Graphs
To add anomaly detection to a graph in Datadog:
- Go to the graph and click "Edit."
- In the editor, click "Functions" and select "Anomaly Detection."
- Choose the algorithm (Basic, Agile, or Robust) and set the bounds (e.g., 2 or 3).
- Click "Apply" to save.
Understanding Anomaly Bands
Anomaly bands show the expected range of values for a metric. They are calculated from historical data and indicate when a metric is behaving unusually. The bands are shaded areas on the graph, with the darker area showing the expected range and the lighter area showing the anomaly detection bounds.
Customizing Visuals
You can customize how anomaly detection looks on your graphs to make it easier to see and understand. For example, you can:
| Customization | Description |
|---|---|
| Change colors | Make anomalies more noticeable by changing the color scheme. |
| Adjust opacity | Make anomaly bands more or less visible by changing their opacity. |
| Add more data | Include additional metrics or data points to provide more context. |
Advanced Configuration
Handling Seasonal Patterns and Trends
Your data may have seasonal patterns or trends that can impact anomaly detection accuracy. Datadog's algorithms can adapt, but you may need to adjust the configuration.
For example, if monitoring a metric with daily or weekly fluctuations, choose the Agile algorithm. It's sensitive to seasonality and can quickly adjust to level shifts. If the metric has a relatively level baseline, the Robust algorithm may work better.
Adjusting Parameters
You can adjust the bounds parameter to optimize anomaly detection. bounds determines the algorithm's tolerance and the width of the "normal" gray band. Think of bounds as deviations from the predicted value.
For most metrics, setting bounds to 2 or 3 will capture most "normal" points in the gray band. However, you may need to adjust this value based on your use case. For example, if monitoring a highly variable metric, set bounds higher to reduce false positives.
Troubleshooting
If experiencing issues, try these steps:
| Step | Description |
|---|---|
| Check Data | Ensure data is clean and error-free. Anomalies in data can lead to inaccurate results. |
| Adjust Algorithm | Switch to a different algorithm to improve accuracy. |
| Tune Parameters | Adjust bounds to reduce false positives or false negatives. |
Integrating with Other Features
Combining with Log Management
Datadog's log management tools can give you more details about anomalies found by the anomaly detection system. By connecting log data with anomaly detection, you can find the root cause of anomalies and fix issues faster. For example, if an anomaly is detected in a metric, you can use log data to see the specific errors or warnings that may be causing the anomaly.
Using with Tracing and APM
You can also use anomaly detection together with tracing and Application Performance Monitoring (APM) to find performance issues in your applications. By detecting anomalies in trace data, you can identify bottlenecks and delays that may be impacting user experience. Additionally, anomaly detection can be used to detect issues in APM data, such as errors or slow responses, which can help you improve your application.
Proactive Monitoring
Anomaly detection can be used for proactive monitoring by finding potential issues before they impact users. By setting up anomaly detection on key metrics, you can get alerts when anomalies are detected, allowing you to take action before issues get worse. This can help reduce the time it takes to detect and resolve issues, leading to better uptime and user satisfaction.
| Feature | Benefit |
|---|---|
| Log Management | Find root causes of anomalies faster |
| Tracing & APM | Identify performance bottlenecks and errors |
| Proactive Monitoring | Detect issues before users are impacted |
