How to Get Infinite Custom Metrics For Free

The text discusses the advantages of integrating infrastructure metrics directly into structured logs and trace spans instead of relying solely on traditional time-series metrics for monitoring applications. By embedding metrics such as memory usage and CPU load into logs or spans, developers can gain immediate context about system performance during specific application events, facilitating a more precise diagnosis of issues like memory errors. This approach allows for a more holistic view of system behavior, enabling correlation of metrics with application performance and reducing the need for separate data sources, although traditional time-series metrics remain important for infrastructure monitoring. The text also highlights the potential cost savings and efficiency improvements offered by this method, especially when using advanced observability platforms like Honeycomb, which can aggregate and analyze these metrics quickly and affordably. However, it notes that the effectiveness of this approach depends on the capabilities of the observability platform in use.
