# Issues

- [Suspected N+1](https://docs.digma.ai/digma-developer-guide/digma-features/insights/suspected-n+1.md): N+1 queries are usually a result of modeling issues created by ORMs. They manifest in an excessive number of queries that can carry a performance cost.
- [Excessive API calls (chatty API)](https://docs.digma.ai/digma-developer-guide/digma-features/insights/excessive-api-calls-chatty-api.md): Digma can detect situations of excessive API chatter between different microservices or to different APIs and point them out.
- [Bottleneck](https://docs.digma.ai/digma-developer-guide/digma-features/insights/bottleneck.md): This insight identifies assets that hold up requests by taking a large portion of their time. An asset will not be considered a bottleneck if it is a part of a non-blocking asynchronous execution.
- [Scaling Issue](https://docs.digma.ai/digma-developer-guide/digma-features/insights/scaling-issue.md): The scaling issue insight analyzes how the code performs when running concurrently and automatically tries to RCA the cause of any performance issues.
- [Session In View Query Detected](https://docs.digma.ai/digma-developer-guide/digma-features/insights/session-in-view-query-detected.md): Open Session in View is a common anti-pattern in which the database session is left open during view rendering, possibly resulting in lazy database queries at the rendering phase.
- [Query Optimization Suggested](https://docs.digma.ai/digma-developer-guide/digma-features/insights/query-optimization-suggested.md): This insight identifies queries that are abnormally  slow and are considered candidates for optimization
- [High number of queries](https://docs.digma.ai/digma-developer-guide/digma-features/insights/high-number-of-queries.md): This insight identifies endpoints that trigger an abnormal amount of queries. This can be caused by abstraction issues or not using bulk queries when applicable
- [Slow Endpoint](https://docs.digma.ai/digma-developer-guide/digma-features/insights/slow-endpoint.md): This insight provides an indication if a particular endpoint is slower than others by a substantial degree
