When troubleshooting issues, finding the root cause of a problem as quickly as possible is critical. Palo Alto Networks Cortex XCOR includes the Cortex XCOR Differential Diagnosis (DDx) feature to help developers find the source of slowdowns or failures by identifying suspicious trends in your telemetry data and what’s causing them. DDx lets developers resolve service performance issues without writing queries or needing knowledge of the entire system. DDx ranks and highlights the most probable sources of issues so developers can test hypotheses and compare trends to identify root causes.

Identify issues in traces

In Trace Explorer or from service pages, use DDx for traces to identify trends and immediately scan through all related tags and values to pinpoint the exact tag:value pairs most closely correlated with suspicious behavior. In Metrics Explorer or from service pages, use DDx for metrics to examine time series anomalies, such as unusual shapes in their metrics like spikes and dips, and quickly understand what dimensions are contributing to an issue.
