KV Processor

edit

This processor helps automatically parse messages (or specific event fields) which are of the foo=bar variety.

For example, if you have a log message which contains ip=1.2.3.4 error=REFUSED, you can parse those automatically by configuring:

{
  "kv": {
    "field": "message",
    "field_split": " ",
    "value_split": "="
  }
}
