-The _expect_ filter plugin allows you to validate that records match certain criteria in their structure, like validating that a key exists or it has a specific value.

-## Configuration Parameters
+## Configuration parameters
 
 The plugin supports the following configuration parameters:
 
 | Property | Description |
 | :--- | :--- |
-| key\_exists | Check if a key with a given name exists in the record. |
-| key\_not\_exists | Check if a key does not exist in the record. |
-| key\_val\_is\_null | check that the value of the key is NULL. |
-| key\_val\_is\_not\_null | check that the value of the key is NOT NULL. |
-| key\_val\_eq | check that the value of the key equals the given value in the configuration. |
-| action | action to take when a rule does not match. The available options are  `warn` , `exit` or "result_key". On `warn`, a warning message is sent to the logging layer when a mismatch of the rules above is found; using `exit` makes Fluent Bit abort with status code `255`; `result_key` is to add a matching result to each record. |
-| result\_key | specify a key name of matching result. This key is to be used only when 'action' is 'result_key'.|
