The settings view now has a new look! The previous tabular layout is replaced with tiles, making the UI more intuitive and easier to navigate. No functionality changes.

Following up on our recent improvements to Volume alerts, we've released a similar set of improvements for managing Freshness alerts (time since last update & time since last row count change). Same as the Volume release, we’re rolling this out gradually over the next few weeks. It is currently available to just a subset of customers.

Specific improvements:

• Freshness thresholds don't automatically widen after an anomaly. Instead, anomalies are excluded by default from the set of training data. If they don’t want to be alerted to similar anomalies in the future, users can ‘Mark as normal’. This will re-introduce the anomalous data point to the training set and widen the threshold.
• Users can 'select training data' directly in the freshness chart. This gives the user full control over which data is used to train the model, without needing to navigate to Settings to create Exclusion Windows.

With this change, all anomaly detection in Table monitors (Freshness & Volume) now behaves the same way. Anomalies are excluded anomalies by default from the data set that trains thresholds. And users can then choose to add them back in if they’d like to widen the threshold.

In addition to the existing workflow of sending alerts to ServiceNow via audiences, users can now minimize alert noise within their ServiceNow environments by manually reviewing alerts before forwarding them or linking alerts to existing ServiceNow incidents.

We've redesigned the monitor list and added new bulk actions, filtering, and sorting capabilities to simplify a variety of monitor management workflows such as:

• Sorting monitors by alert frequency and bulk disabling or snoozing noisy monitors to reduce alert fatigue
• Sorting monitors by run and bulk editing their schedule configuration to spread out monitor runs
• Sorting monitors by last run to review and bulk delete stale monitors
• Bulk running monitors to test newly created ones quickly
• Adjusting the columns and displaying the information that matters most to each user

You can now configure monitor alert notifications and monitor failure notifications with different audiences in order to route issues to the appropriate stakeholders while minimizing noise and alert fatigue.

Last year, we released a big set of improvements to the Metric monitor that improved anomaly detection and the user experience on the Alert page. As part of this, we released a new metric property in Monitors as Code and the API.

Users have still been able to create monitors under the old “field_health” property, though its use to create new monitors has dwindled.

As of March 1, 2025:

• Users will no longer be able to create new monitors using the field_health property. Existing monitors using that property will continue to function without interruption and will still be editable. When creating new Metric monitors, users should use the metric property instead. The differences between the field_health and metric properties are modest, and a guide for how to navigate the two is here.
• Users will no longer be able to use the createOrUpdateMonitor mutation to create a Metric monitor via the API/CLI. Customers should use createOrUpdateMetricMonitor mutation instead. Existing monitors will continue to function without interruption.

We're simplifying how users provide feedback to our anomaly detection models.

Up until recently, users had the option to "Share feedback" on any Alert in Monte Carlo. If the user marked the anomaly as "Helpful" in that workflow, then Monte Carlo would remove that anomaly from the set of data that was used to train thresholds. This would then restore thresholds to pre-anomaly levels.

This workflow has been deprecated and removed. Rationale:

• This workflow had a duplicative effect to marking the alert status as "Fixed". Having multiple workflows with the same effect was confusing.
• We're transitioning to a model where anomalies are excluded from training by default, and users can add them back in through a "Mark as normal" workflow. Read more.

Users can now automatically provision and deprovision Monte Carlo users and authorization groups via their identity providers. Currently supporting Okta and Microsoft Entra ID.

The volume monitor has been rebuilt to address a broad set of customer feedback from the past year. This will be a phased release to customers over the next few weeks, and it is currently available to just a subset of customers. These improvements apply just to Volume, but we intend to expand them to all monitors over the coming months.

Key improvements:

• Dramatically better anomaly detection. The thresholds are much tighter, particularly for very regular tables.
• Thresholds don't automatically widen after an anomaly. Instead, anomalies are excluded by default from the set of training data. If users don’t want to be alerted to similar anomalies in the future, they can ‘Mark as normal’. This will re-introduce the anomalous data point to the training set and widen the threshold.
• Users can 'select training data' directly in the chart. This gives the user control over which data is used to train the model. This is especially useful for excluding undesirable data when the monitor is initially training.

We built Data Profiler to help technical and non-technical users quickly deploy effective data quality monitoring on important assets. We're now introducing recommendations powered by large language models (LLMs) that analyze data samples, table metadata, and query logs to tailor monitoring to each asset:

• Multi-column validations to monitor relationships between columns e.g. start_date should be before end_date.
• Regular expression validations to enforce arbitrary patterns and formats in data that go beyond basic checks like UUID matching or email format.
• Segmented volume and freshness to track row count or time since last row count change for segmented data such as sales by store or inventory by warehouse.
