The collector further enhances this process by aggregating and processing data from multiple sources before sending it to backend systems for analysis. This helps reduce noise and ensures that only relevant, high-quality telemetry data is captured and analyzed, improving the accuracy and utility of observability insights.
Cost Efficiency and Control
OpenTelemetry’s preprocessing capabilities enable users to filter out non-essential data, manage metric cardinality, and follow semantic conventions, resulting in significant cost savings. By processing only actionable data, operational expenses are greatly reduced. This preprocessing step is essential for managing the volume and complexity of telemetry data in large, distributed systems. By filtering out redundant or irrelevant data, organizations can focus their resources on analyzing meaningful insights that drive business value. This selective data processing helps avoid the high costs associated with storing and querying vast amounts of telemetry data.
Furthermore, OpenTelemetry’s adherence to semantic conventions ensures consistency in the way telemetry data is labeled and interpreted.
