## Key Highlights

Logs View v2 with Tool Call Tracing - Redesigned logs interface with side panel, structured tool visualization, and error message search for faster debugging.

Let's dive in.

### Logs View v2 with Tool Call Tracing

This release introduces comprehensive tool call tracing through LiteLLM's redesigned Logs View v2, enabling developers to debug and monitor AI agent workflows in production environments seamlessly.

This means you can now onboard use cases like tracing complex multi-step agent interactions, debugging tool execution failures, and monitoring MCP server calls while maintaining full visibility into request/response payloads with syntax highlighting.

Developers can access the new Logs View through LiteLLM's UI to inspect tool calls in structured format, search logs by error messages or request patterns, and correlate agent activities across sessions with collapsible side panel views.
