Log format

After analyzing the provided web search results, I can now provide a comparison between the Elastic Common Schema (ECS) log format and other commonly used log formats, such as JSON and plain text. Here is a table comparing the differences:

Log Format	Description	Advantages	Disadvantages
ECS Log Format	A standardized log format used by Elastic Stack to provide a consistent way to structure logs across different data sources [2]	- Uniform data modeling - Easier analysis and correlation - Semi-structured format - Human-readable JSON [1]	- Specific to Elastic Stack
JSON Log Format	A semi-structured log format containing multiple key-value pairs [8]	- Human-readable - Easy to parse - Widely supported	- Verbose
Plain Text Format	Unstructured log format consisting of human-readable text without a fixed structure [7]	- Easy to read and write - Compatible with many tools and systems	- Difficult to parse and analyze

Please note that this comparison is not exhaustive and only includes a few popular log formats. There are many other log formats, and the choice of log format depends on the specific requirements and constraints of the system or application generating the logs.

[5] "A log format is a structured format that allows logs to be machine-readable and easily parsed. This is the power of using structured logs and a log management system that supports them. The ability to translate raw data into something immediately comprehensible and easy to read is one of the must-have features of log management software."

[8] "While log formats vary widely across systems, applications, and tools, certain log formats are commonly used. Let's cover the notable ones in more detail. JSON JavaScript Object Notation (JSON) is one of the most commonly used log formats. JSON logs are semi-structured, containing multiple key-value pairs."
