Setting up monitors

Anomaly monitors can help you catch important issues you may otherwise not have caught and are a core component of building reliability in business-critical data products.

​

Monitor setup considerations

It’s essential to balance coverage and signal-to-noise ratio. While maximal monitoring across the stack may be appealing, it is not always the best option. It can cause alert fatigue and wear out your data team, causing important issues to be overlooked. The right monitor placement strategy can help with this.

We’ve written extensively about how to best set up your monitoring in the SYNQ Data Product’s guide. Here are a few guidelines.

​

Designing a Testing Strategy

A well-structured testing strategy ensures comprehensive coverage across the data platform while minimizing redundancy. This involves defining testing approaches for each layer—sources, transformations, and data products—and considering how e.g., dbt tests complement SYNQ’s anomaly monitors to avoid redundant testing.

​

Testing Sources

Testing at the source layer is critical because errors propagate downstream. Since this layer has the most dependencies, a strong foundation reduces the need for excessive testing further down the pipeline. See more in the Testing sources section of our guide.

​

Testing Transformations

Once sources are well-tested, transformation testing can focus on verifying changes rather than duplicating checks already performed upstream. This includes validating logic and aggregations after joins. A targeted approach ensures transformations produce accurate and reliable results without unnecessary overhead. See more in the Testing transformations section in our guide

​

Testing Data Products

Data product testing should be targeted and ideally done by data people with the relevant domain expertise. Instead of focusing on technical aspects of data, when testing data products, you should verify the logic encoded in SQL transformations. See more in the Testing products section of our guide.

Setting up monitors

There are two ways to set up monitors in SYNQ.

​

1. Add a monitor to an individual table

Set up monitors one table at a time. This is great for targeted monitoring where you just want to monitor specific tables. It’s also the only way to define custom monitors.

1. Navigate to the table or data model in SYNQ (e.g., by using the Catalog or Search functionality)
2. Click the +Add button and select a monitor type

​

2. Deploy monitors at scale

Use deployment rules to deploy monitors to many tables at once. For example, you can automatically add monitors to all sources upstream of a data product - the rule will also ensure that new sources added automatically will have monitors deployed.
