Data + Model Monitoring with WhyLabs: simple, customizable, actionable
- ML Monitoring
Aug 16, 2022
Today, WhyLabs Observatory monitors hundreds of machine learning models and data streams. Our customers rely on us to alert them about data drifts, data quality issues, model performance degradations, and more. Every monitoring experience begins with setting up configurations, but if it’s not simple and reliable, that’s where the experience ends. To make sure our customers can easily configure monitoring on our platform, we focused our recent product efforts on refining the Observatory’s monitoring configuration experience. The new monitoring system maximizes the helpfulness of alerts and minimizes alert fatigue, so users can focus on improving their models instead of worrying about them in production. Today, we are excited to announce a new version of the WhyLabs monitoring system that allows users to:
- Create custom-tailored monitors for any data and ML monitoring use case.
- Switch on preset monitors with zero-configuration.
- Tune each monitor's severity and notification pattern to achieve reliable alerting.
Customizable monitoring for any use case
Our customers come from a myriad of industries including logistics, healthcare, fintech, retail, HR tech, and martech. What unites them is their reliance on the WhyLabs Observatory to provide a flexible monitoring experience for their models and data. Customizable monitoring enables them to do this efficiently.
With our new monitoring system, you can:
- Select the exact set of features you would like to monitor
- Configure the most suitable analysis: static thresholds, standard deviation, percent change, and many more
- Choose the most suitable baseline: training data (reference), trailing window, or reference date range.
- Customize the appropriate severity and the action that should be taken on alert: this can include notifying you about the anomaly, automatically retraining an ML model, rolling back a data pipeline change, and more.
Start simple: one-click Preset monitors
While fully-customizable monitoring satisfies the most fine-grained use cases, not everything requires this level of tuning. When customers start using WhyLabs Observatory, they often prefer a simple way to switch on monitoring for their data and ML models. Our newest release makes this possible!
The Presets monitoring experience makes it easy for users to configure the most essential monitors with a single click. API access is also available for turning on Preset monitors programmatically. These Presets intelligently configure granular monitors based on the data in the dataset or machine learning model. This approach allows monitoring to be configured for a model with thousands of features in just a few clicks. For those who love to be in control, you’re able to fine-tune the configurations to minimize unhelpful alerts.
One application of these Preset monitors is allowing enterprises who are monitoring dozens or hundreds of ML models and data streams to efficiently set up monitoring on those assets. In fact, our customers can configure the Observatory to automatically monitor new models and data streams by integrating WhyLabs with their data and model deployment systems.
If you are interested and ready to dive in, check out the Monitor Manager documentation or try it out for yourself by signing up for the platform for free. If you’d rather go through a few examples first, read on as we cover enabling a Preset monitor for a fraud classification model and customizing a monitor for a data stream.
Model Monitoring: a fraud classification example
To see the monitoring experience in action, let’s walk through a classic example: a fraud classification model. We set up an observability Project that monitors the health of this model on the WhyLabs platform.
About the model: it takes in a number of features about a transaction, including the amount, country, and type, and outputs a prediction of whether this transaction is fraudulent or not.
How it works: If a transaction is predicted to be fraudulent, it is routed to a human analyst to determine whether or not it was fraudulent. If a transaction isn’t predicted to be fraudulent, it also has some probability of being routed to a human so the model can get continuous feedback about its performance.
In this scenario, let’s say that I wasn’t previously monitoring my model, and only found out about its performance degradation because my customer support department noticed a significant uptick in fraudulent transaction complaints. I retrain the model and get it back to acceptable performance. But how can I prevent these issues going forward?
Since I have both predictions and ground truth for this model, I can quickly set up a monitor for the model's performance in WhyLabs Observatory. If ground truth was unavailable, I could still monitor the model inputs and outputs to look for data/concept drift or data quality issues that may be affecting the performance of my model.
After signing up for WhyLabs and following the 5 minute tutorial for onboarding my model, I navigate to the Presets tab within the Monitor Manager UI. I then select the ones I need from the different preset monitors available, and enable them with one click.
First, I switch on the F1 Score monitor to get alerted if my model has performance issues. This way, I can be proactive about fixing issues with my model, instead of reacting only after customer service surfaces an issue.
In this case, I am interested in getting an email when my model has a performance issue, so I can resolve it immediately. To do that, I configure the monitor by clicking the Configure button next to that monitor’s card and editing the Action dropdown that appears.
Now, if my model’s performance worsens, I will get an email right away, allowing me to dive in and start fixing the issue immediately. I can configure numerous other components of this Preset monitor, such as setting the appropriate threshold and ensuring that I get only the most relevant alerts.

Data Stream Monitoring: an auction house example
All of our customers rely on data to make business decisions, be it through a machine learning model, real-time analytics, customer-facing dashboards, or quarterly business reports. WhyLabs enables monitoring for any data in motion, no matter what decision-making it powers. In this particular example, we will dive into a streaming data use case.
About the data stream: Let’s monitor a Project which consists of an Apache Kafka stream of real-time data from a video game auction house.
How it works: The video game provides an API that enables users to track information about transactions in the auction house, including the bid amount, the item type, and the time left in the auction when the bid was made.
In this example, I’m the game developer and want to track the health of my application by looking at the data it produces. In particular, I want to track data drift for the transaction ID column because significant drifts in this field can indicate that there’s a bug in the application generating these IDs.
Since I have a specific type of analysis and threshold in mind, I start by setting up a custom monitor. To begin tracking this data drift, I can click the orange “New custom monitor” button to create a new monitor.
Within the custom monitor configuration, I have control over a number of different components of the monitor settings. I can select whether I want to monitor the entire dataset or a specific segment, the sensitivity of the analysis, what to select as a baseline, and more. Check out our monitor documentation to learn more about the options you have when configuring a monitor.
After setting up my custom monitor, I’ll receive both an email and a Slack notification if the transaction ID column has drifted in its distribution. If it has, I can quickly debug whatever problem in my application is causing this distributional change, and thereby ensure the reliability of my data application.
