Enterprise-grade AI-powered observability platform with specialized monitoring for AI agents, natural language querying, and intelligent troubleshooting. Features dedicated AI Agent Monitoring for LLM applications and agentic workflows, plus AI troubleshooting agents that automatically correlate signals and provide evidence-based root cause analysis.
Splunk Observability Cloud with AI capabilities represents the evolution of enterprise observability into the AI era. Following Cisco's acquisition of Splunk, the platform has become a comprehensive solution for monitoring both traditional applications and the new wave of AI-powered systems including LLM applications, AI agents, and supporting infrastructure.
The platform's centerpiece is AI Agent Monitoring, now generally available, which provides specialized observability for AI applications. This includes tracking performance metrics like latency and errors alongside quality metrics such as hallucinations, bias, drift, and accuracy, as well as cost and token usage analytics. Teams can trace and map dependencies across LLM calls, tool executions, and other service interactions to correlate model quality with business impact.
Enterprise-grade monitoring for AI agents and LLM applications built on Datadog's infrastructure platform. Provides end-to-end tracing, cost tracking, quality evaluations, and security detection across multi-agent workflows.
