The 3 pillars of observability: Logs, metrics and traces. Logs: Logs provide essential insights into raw system information, helping to determine the occurrences within your database. An event log is a time-stamped, unalterable record of distinct events over a specific period. Metrics: Metrics are numerical representations of data that can reveal the overall behavior of a service or component over time. Metrics include properties such as name, value, label, and timestamp, which convey information about service level agreements (SLAs), service level objectives (SLOs), and service level indicators (SLIs). Traces: Traces illustrate the complete path of a request or action through a distributed system's nodes. Traces aid in profiling and monitoring systems, particularly containerized applications, serverless setups, and microservices architectures.
