Logging Deep Dive and Best Practices
The following video was recorded at KubeCon + CloudNativeCon North America in November 2023. We are grateful to the Cloud Native Computing Foundation for allowing us to post it here.
The Challenges of Logging
Log collection and analysis is an essential part of understanding what is going on with our systems. However, logging brings challenges:
Log formats differ across systems and applications
Logs can be collected in different ways, including from file systems, APIs, and network endpoints
The sheer volume of logs produced can be difficult to manage
This is where Fluent Bit comes in. Fluent Bit is a unified solution for collecting, processing, and routing telemetry data. In addition to logs, Fluent Bit can also handle metrics and traces.
Logging Best Practices
In this section, Anurag Gupta demonstrates how Fluent Bit can be used to solve various problems, including
Enriching logs with additional information, such as hostname
Keeping debug and trace logs out of expensive storage and analytical backends
Redacting or removing sensitive data such as credit card numbers
Converting logs to metrics for easier monitoring on dashboards and reporting
Monitoring and Operations
In the final section of the presentation, Jose Lecaros demonstrates various ways to monitor your Fluent Bit data pipelines and troubleshoot potential issues including:
Using Grafana to visualize the metrics that Fluent Bit generates about its own health and status
Identifying issues where your destination endpoint cannot handle the current volume and how Fluent Bit provides both in-memory and file system buffering to reduce back pressure and ensure that no data is lost.
