Telemetry
Overview
Telemetry systems collect, transmit, and analyze data from devices, sensors, and systems to provide real-time visibility and historical insight.
They are critical for monitoring system health, performance, and operational behavior.
🎯 Scope
- Metrics and system data collection
- Sensors and data sources
- Reporting and visualization
🧠 Key Concepts
- Telemetry provides visibility into system behavior
- Data must be meaningful, not excessive
- Collection frequency impacts performance and storage
- Telemetry feeds alerting, automation, and AI systems
System Architecture
Data Collection
- Sensors, devices, and system metrics
- Capture relevant signals only
- Avoid unnecessary data volume
Data Transport
- Move telemetry data efficiently
- May use local or cloud pipelines
- Must be reliable and secure
Reporting & Analysis
- Dashboards and visualization
- Historical trends and analysis
- Supports decision-making and automation
⚠️ Common Mistakes
- Collecting too much data without purpose
- No retention strategy
- High-frequency polling causing performance issues
- No validation of data accuracy
- No integration with alerting or analysis systems
