Palo Alto Networks Cortex XCOR is an AI-powered observability platform that provides monitoring, troubleshooting, and operational intelligence across applications, infrastructure, and end-user experiences. The platform collects and analyzes logs, metrics, traces, and events to provide visibility into distributed systems and cloud-native environments. Its XCOR Operator provides a conversational interface that enables engineers to query system data, investigate performance issues, configure alerts, and create dashboards using natural language. AI Investigations automatically correlates telemetry signals and system dependencies to identify probable root causes and reduce incident resolution times. Operational Fabric maintains contextual information about system topology, historical incidents, user behavior, and operational knowledge to support AI-driven investigations. Application observability capabilities include automated service discovery, dependency mapping, service-level objective monitoring, and distributed tracing. Real user monitoring and synthetic monitoring help teams evaluate application responsiveness, browser performance, and potential issues affecting digital experiences. The platform's Optimization Engine identifies low-value telemetry and applies filtering, sampling, and aggregation rules to reduce unnecessary data storage costs. Cortex XCOR supports OpenTelemetry-based data collection, scalable infrastructure monitoring, and consumption budgets for controlling observability spending across enterprise environments.
