Already Love Scout APM? We Have Integrated Error Monitoring!
Error monitoring is now fully integrated with APM, with errors, traces, and logs in one interface. When an error spikes, you can immediately see if it correlates with a performance regression, drill into the trace, and find the problematic code without switching tools or piecing together data from multiple sources. Scout treats errors like first-class citizens, not an afterthought. This means that the integration depth and actionability is different than other tools: in Scout, errors and traces live in the same view by design, not as bolt-on features.
