description: Monitor CPU, memory, and resource usage of a running Tauri application
allowed-tools: mcp__tauri-mcp__monitor_resources
author: Quintin Henry (https://github.com/qdhenry/)

<objective> Monitor the resource consumption of a running Tauri application to identify performance issues or memory leaks. </objective>

<instructions> Monitor resources for the Tauri application: **$ARGUMENTS**

Arguments: `[process_id]`

Process

1. **Query Resource Metrics** Use `mcp__tauri-mcp__monitor_resources` with the process ID.

2. **Analyze Results**

• Compare to expected baselines
• Identify concerning metrics
• Note trends if called repeatedly

3. **Provide Recommendations** Based on the metrics, suggest:

• Whether performance is acceptable
• Potential issues to investigate
• Next debugging steps if needed

Usage Examples

# Check current resource usage
/tauri:resources 12345

# Use in a monitoring loop (manual)
/tauri:resources 12345
# wait, perform actions
/tauri:resources 12345
# compare results

</instructions>

=== Resource Usage ===
Process ID: [PID]
Timestamp: [time]

--- CPU ---
Usage: [X]%
[assessment: low/moderate/high]

--- Memory ---
Resident: [X] MB
Virtual: [X] MB
[assessment: normal/elevated/concerning]

--- Other Metrics ---
[any additional available metrics]

--- Assessment ---
[Overall health: Good/Warning/Investigate]
[Recommendations if any]

</output_format>

<baselines> **Typical Healthy Values (Tauri Desktop App):**

• CPU Idle: < 5%
• CPU Active: < 30% (during normal use)
• Memory: 100-300 MB (depends on app complexity)
• Memory Growth: Should stabilize, not grow indefinitely

**Warning Signs:**

• CPU > 50% when idle
• Memory > 500 MB for simple apps
• Continuous memory growth (potential leak)
• CPU spikes during simple operations

</baselines>

<use_cases> **Performance Testing:** Measure resource usage during specific operations.

**Memory Leak Detection:** Monitor over time to detect growing memory usage.

**Optimization Validation:** Compare before/after metrics when optimizing code.

**CI/CD Integration:** Automated resource checks in test pipelines. </use_cases>
