[FEATURE] Implement Asynchronous Telemetry and Metrics Export for Node and Command Usage Statistics in osvm-cli

---

🚀 Problem Statement

To enable data-driven improvements of osvm-cli, we need to collect telemetry and usage metrics for nodes and commands asynchronously without degrading CLI performance or user experience. This feature will:

• Provide insights into how the CLI is used in real environments
• Help prioritize future enhancements based on real-world data
• Enable monitoring of node interactions and command executions over time

Telemetry data should be exported asynchronously to avoid blocking CLI operations, preserving responsiveness and reliability.

---

🧠 Technical Context

• Repository: openSVM/osvm-cli — a Rust-based CLI for managing Solana Virtual Machines
• Current State: No asynchronous telemetry or metrics export exists.
• Primary Language: Rust (1.80.0+)
• Architecture: Modular CLI commands managing SVM nodes, with ongoing refactors targeting modularization and safer argument handling.
• Constraints: Minimal runtime overhead, no blocking on network or disk IO, safe error handling with no user disruption.

---

🛠 Detailed Implementation Steps

1. Research and Define Telemetry Scope

   • Investigate existing telemetry solutions compatible with Rust CLI apps (e.g., opentelemetry-rust, metrics)
   • Decide on telemetry data points:
     • Command usage counts, durations, success/failure states
     • Node interaction stats (connection attempts, commands sent)
     • Environment/context metadata (OS, CLI version, etc)
   • Choose export targets (e.g., remote HTTP endpoint, local file, or a pluggable backend)

2. Design Async Telemetry Architecture

   • Use asynchronous Rust primitives (tokio, async-std) for non-blocking telemetry gathering and export
   • Define a telemetry client interface that buffers metrics/events and flushes periodically or on CLI exit
   • Ensure error resilience: telemetry failures must not affect CLI commands or user experience
   • Respect privacy: allow users to opt-out or anonymize data as needed

3. Implement Telemetry Core

   • Create a Rust crate/module telemetry inside the repo:
     • Interfaces for metrics recording (counters, histograms, gauges)
     • Async exporter task running in background with buffered queue
     • Configurable export intervals and backoff strategies
   • Integrate with CLI command execution flow:
     • Wrap commands with telemetry start/stop hooks capturing execution metrics
     • Capture node API usage statistics during command processing

4. Build MVP Version

   • Support basic command usage counting and timing telemetry
   • Export data asynchronously to a local file or mock HTTP endpoint
   • Provide CLI flag/config option to enable/disable telemetry

5. Gather Feedback and Iterate

   • Deploy MVP to internal users or beta testers
   • Collect feedback on performance impact, data usefulness, privacy concerns
   • Refine telemetry data schema and export mechanisms accordingly

6. Finalize Documentation and Tests

   • Document telemetry design, configuration options, and privacy policies in README and CLI help
   • Write unit tests covering telemetry client logic, async export, and integration with CLI commands
   • Add integration tests simulating command runs with telemetry enabled

🧩 Technical Specifications

• Telemetry Data Model:

  struct TelemetryEvent {
      timestamp: DateTime<Utc>,
      command_name: String,
      execution_duration_ms: u64,
      success: bool,
      node_id: Option<String>,
      metadata: HashMap<String, String>,
  }

• Async Exporter:

  • Use Tokio async runtime (tokio::spawn) for background worker thread
  • Buffer events in a thread-safe queue (tokio::sync::mpsc)
  • Flush buffered events every 5 seconds or on CLI exit
  • Retry sending with exponential backoff on export failures

• Configuration:

  • CLI flag: --enable-telemetry (default off)
  • Config file option: telemetry.enabled = true/false
  • Export endpoint URL configurable via environment variable or config

• Privacy & Compliance:

  • Telemetry data must be anonymized — no PII collected
  • Provide clear opt-out instructions and defaults to disabled

---

✅ Acceptance Criteria

• Telemetry data collection interfaces defined and implemented
• CLI commands instrumented to record telemetry asynchronously
• Telemetry data exported without blocking or impacting CLI responsiveness
• Configuration options for enabling/disabling telemetry implemented
• MVP exports basic command usage metrics to a local file or mock endpoint
• Unit and integration tests cover telemetry logic and CLI integration
• Documentation updated with telemetry feature description, configuration, and privacy info
• Feedback collected from initial users and used to plan next iterations

---

🧪 Testing Requirements

• Unit Tests:

  • Telemetry event creation and serialization
  • Async exporter buffering and flushing logic
  • Error handling and retry mechanisms

• Integration Tests:

  • CLI runs with telemetry enabled, verifying data is recorded and exported
  • CLI responsiveness benchmarks comparing telemetry enabled vs disabled
  • Opt-out scenarios ensuring no telemetry is collected when disabled

• Manual Testing:

  • Validate telemetry data correctness and completeness in exported files or endpoints
  • Check CLI UI/UX remains smooth with telemetry enabled
  • Test configuration flags and environment variable overrides

---

📚 Documentation Needs

• Add a new section in the main README describing:

  • Purpose and benefits of telemetry
  • How telemetry data is collected and used
  • How to enable/disable telemetry via CLI flags and config
  • Privacy and data anonymization policies

• Update CLI help output (--help) to mention telemetry options

• Document telemetry architecture and implementation details in an internal design doc for maintainers

---

⚠️ Potential Challenges

• Performance Impact: Ensuring telemetry collection and export does not block or slow down CLI commands, especially under heavy usage
• Error Handling: Telemetry failures must be silent and non-disruptive; requires robust retry and backoff strategies
• Privacy Concerns: Avoid collecting any personally identifiable information inadvertently
• Modular Integration: Refactoring main.rs and command modules to cleanly inject telemetry hooks without tangled dependencies
• Testing Async Code: Reliable testing of async telemetry export and concurrency handling can be complex
