Plugin Demo: AI Agent querying DLT logs, opening a Markdown report widget, and clicking links to navigate the log window Workflow example: Requesting an analysis via an AI Agent (e.g., OpenCode), which generates a Markdown report directly inside the DLT Viewer widget. Clicking links in the report instantly navigates to the specific messages in the log window.

Features

Search: Filter log messages by CTID, APID, log level, timestamp range, and specific keywords matched against payloads. Includes pagination support, control of case sensitivity and payload previews.
Message Retrieval: Fetch the full, un-truncated payloads for specific message IDs.
Selection: Allow the AI agent to read details of the currently selected message in your DLT Viewer window.
Context File: Provide a context file with any instructions you’d like to provide to your AI agent.
Interactive Reporting: Generate and display formatted Markdown reports in the plugin widget. Includes clickable links that navigate the main DLT Viewer log window to exact messages.
Persistence: Generated reports are persisted and automatically loaded alongside the matching DLT file or collection of files. Report browser lets you view and manage your report history.
