Overview
Dynatrace automatically detects all applications and microservices deployed in your system and how it uses your database. It provides automatic end-to-end tracing down to a single database statement, database server metrics and log insights. Dynatrace visualizes application to database dependencies for SQL and noSQL databases as well as for cloud databases and self-hosted databases. It also diagnoses anomalies in real-time using AI and pinpoints the root cause down to the slow performing or erroneous SQL statements. Deep code-level insights combined with cloud-native database server monitoring will help you maintain a robust production environment.
Use cases
- Understand all dependencies of your applications to the database, which database statements are executed and their performance.
- Improve the performance of your application by reducing or optimizing typical database patterns like the 1+N query problem
- Understand the resource impact that your applications have on your database.
- Understand the impact of resource shortages, locks or other database issues have on your application by observing the database server itself.
