What is structured logging in C#?
A structured log event, rather than being a line of text, is conceptually a timestamped set of name/value properties. Structured logging systems separate the way the event is captured (the logging API) from the way that it is transported (perhaps JSON) and how it is rendered in a user interface or file.
Are log files structured or unstructured?
According to Wikipedia, unstructured data is “information that either does not have a pre-defined data model or is not organized in a pre-defined manner.” Log files are unstructured text data by default.
Does log4net support structured logging?

What are the benefits of a structured log?
On the outset, having logs well-defined and structured (like JSON) has multiple benefits, including but not limited to: Better root cause analysis : With structured logs, we can ingest and perform more powerful queries which won’t be possible with simple unstructured logs.
What are some use cases for structured logging?
Structured logging can be used for a couple different use cases: Process log files for analytics or business intelligence – A good example of this would be processing web server access logs and doing some basic summarization and aggregates across the data.
Why are logs important to the backend of a system?
Out of these, logs provide the most complete picture of what happened within the system – and is typically the first and most engaged point of contact. With good logs, the backend becomes much easier to understand, maintain, and debug.
What does like conditions look like in structured logging?
LIKE conditions require comparisons with every text row value; again, this is relatively computationally expensive, particularly so when wildcards are used: With structured logging, your disk-error related log message might look like this in JSON:
