So, system engineering teams need complete insights into the system's workings.
Observability allows developers to understand what issues may occur, why they appear, and how to fix and prevent them promptly.
Key components of observability in DevOps include traces, logs, and metrics.
Tracing allows you to view requests or transactions within the application. This practice enables you to identify bugs and define their root causes. By monitoring and analyzing the traces of requests, you can figure out what is happening across the request chain. Tracing is essential because you can determine each issue's real cause and view each system component's real-time performance.
Logs are text records about certain events within the system over a particular time. Logging ensures that you can spot unpredicted behavior during application usage. There are three main types of logs:
- Plain text: This is the data in the form of characters of readable material;
- Structured: JSON-formatted event logs may be sent in a structured form;
- Binary: These logs come in MySQL binlogs, pflog, or the protobuf format.
Metrics refer to the use of specific indicators for streamlined application observability. The measurement sources, including hosts, infrastructure, and cloud platforms, can differ. For instance, metrics can be invaluable indicators for further analysis, whether it's the memory consumption of a particular pipeline or the number of requests an application processes every second.
