When users click on CPU or Memory gauge cards on the agent detail page, a modal dialog displays the top 10 processes consuming that resource with detailed information (PID, name, CPU%, memory, user). + +### What Was Accomplished + +1. **Database Migration (036_process_metrics.sql)** + - Added `top_processes_cpu` JSONB column to metrics table + - Added `top_processes_memory` JSONB column to metrics table + - Stores top 10 processes for each resource type + +2. **Agent Updates (Rust)** + - Created `ProcessInfo` struct with fields: pid, name, cpu_percent, memory_bytes, user + - Implemented `collect_top_processes()` method using sysinfo crate + - Collects and sorts processes by CPU usage and memory usage separately + - Integrated into main metrics collection with graceful error handling + +3. **Backend Updates (Rust)** + - Updated database layer structs (Metrics, CreateMetrics) with JSONB fields + - Modified insert_metrics query to store process data + - Added ProcessInfo struct to WebSocket handler + - Updated MetricsPayload struct to receive process data from agents + +4. **Frontend Updates (TypeScript/React)** + - Added ProcessInfo interface to API client + - Extended Metrics interface with process fields + - Enhanced GaugeCard component with clickable support (onClick, clickable props) + - Created ProcessListDialog modal component using Radix UI Dialog + - Implemented process table with color-coded CPU percentages (green/amber/red) + - Added hover effects for clickable cards + - Made CPU and Memory cards clickable when process data is available + +5. **Deployment to Production** + - Deployed server to 172.16.3.30 + - Applied database migration 036 + - Restarted gururmm-server service + - All agents reconnected successfully + +### Key Decisions and Rationale + +1. **JSONB Storage for Process Data** + - Rationale: Flexible schema, no need for separate tables, efficient for small arrays (10 items) + - Impact: ~1-3KB per metric record, minimal overhead + +2. **Graceful Degradation** + - Made all process fields optional with `#[serde(default)]` + - Old agents without updates continue working normally + - Cards only become clickable when process data is present + +3. **Collection Strategy** + - Collect during regular 60-second metrics intervals (not on-demand) + - Rationale: Consistent data, no additional request overhead, simpler architecture + - Performance: ~50-200ms overhead per collection (<0.35% of 60s interval) + +4. **UI Pattern** + - Modal dialog for process details (not inline expansion) + - Rationale: Consistent with existing UI patterns, keeps page layout clean, allows detailed table view + +### Problems Encountered and Solutions + +**Problem 1: Agent Compilation Error - sysinfo API** +``` +error[E0061]: this method takes 1 argument but 0 arguments were supplied + --> src/metrics/mod.rs:458:18 + | + 458 | .with_user() + | ^^^^^^^^^-- argument #1 of type `UpdateKind` is missing +``` +- **Cause:** sysinfo crate updated API, now requires ProcessesToUpdate and UpdateKind parameters +- **Solution:** Updated call to `system.refresh_processes_specifics(ProcessesToUpdate::All, ProcessRefreshKind::new().with_cpu().with_memory().with_user(UpdateKind::Always))` + +**Problem 2: Server Compilation Error -
