Switch

A switch node is used to filter log records based on a given condition. Only log records matching the condition will be passed to the next nodes, while others will be discarded.

NB: The language used to write conditions is Expr.

Example

{
  "timestamp": "...",
  "fields": {
    "tag": "myapp",
    "content": "hello world"
  }
}
