Why Data Monitoring?

APM (Application Performance Monitoring) tools are used to monitor the performance of applications. APM tools are mandatory part of dev stack. Without AMP tools, it is very difficult to monitor the performance of applications.

But for Data products regular APM tools are not enough. We need a new kind of tools that can monitor the performance of Data applications. Data monitoring tools are used to monitor the data quality of databases and data pipelines. It identifies potential issues, including in the databases and data pipelines. It helps to identify the root cause of the data quality issues and helps to improve the data quality.

What is datachecks?

Datachecks is an open-source data monitoring tool that helps to monitor the data quality of databases and data pipelines. It identifies potential issues, including in the databases and data pipelines. It helps to identify the root cause of the data quality issues and helps to improve the data quality.

Datachecks can generate several reliability, uniqueness, completeness metrics from several data sources

Reports: Data Quality Visualisation

You can generate with just one command. It generates a beautiful data quality report with all the metrics. This html report can be shared with the team.

Validation Funtions Description
Reliability Reliability functions detect whether tables/indices/collections are updating with timely data
Numeric Distribution Numeric Distribution functions detect changes in the numeric distributions i.e. of values, variance, skew and more
Uniqueness Uniqueness functions detect when data constraints are breached like duplicates, number of distinct values etc
Completeness Completeness functions detect when there are missing values in datasets i.e. Null, empty value
Validity Validity functions detect whether data is formatted correctly and represents a valid value
