fluent-bit-plugin-out-expect

Ouput plugin for Fluent-Bit to verify key/value of record.

Feature

• Conditional checking
• Nested field support

Configuration Parameters

Each configuration name should be key_nameN. N is 0-15.

Key Exists

key_existsN Json Object or key_not_existsN Json Object

Json object:

Key	Value Type	Description
"key"	string or string array	The key name to check if it exists or not. If it is array, it is recognized as nested keys.

Example:

use case	example configuration
Key "alert" should be exist	key_exist0 {"key":"alert"}
Key "alert" should not be exist	key_not_exist0 {"key":"alert"}

Boolean

key_boolN Json Object

Json object:

Key	Value Type	Description
"key"	string or string array	The key name to check if it exists or not. If it is array, it is recognized as nested keys.
"value"	boolean	Checking value.
"condition"	string	Checking Condition. "=="/"!="

Example:

use case	example configuration
Value of key "not_nil" should be true	key_bool0 {"key":"not_nil","condition","==", "value":true}
Value of key "not_nil" should be false	key_bool0 {"key":"not_nil","condition","contains", "value":false}

String

key_strN Json Object

Json object:

Key	Value Type	Description
"key"	string or string array	The key name to check if it exists or not. If it is array, it is recognized as nested keys.
"value"	string	Checking value.
"condition"	string	Checking Condition. "=="/"!="/"contains"/"not_contains"

Example:

use case	example configuration
Value of key "name" should be match "Taro"	key_str0 {"key":"name","condition","==", "value":"taro"}
Value of key "name" should be contain "Taro"	key_str0 {"key":"name","condition","contains", "value":"taro"}

Int

key_intN Json Object

Json object:

Key	Value Type	Description
"key"	string or string array	The key name to check if it exists or not. If it is array, it is recognized as nested keys.
"value"	int	Checking value.
"condition"	string	Checking Condition. "=="/"!="/">"/">="/"<"/"<="

Example:

use case	example configuration
Value of key "log_level" should be match 3	key_int0 {"key":"log_level","condition","==", "value":3}
Value of key "log_level" should be greater than 3	key_int0 {"key":"log_level","condition",">", "value":3}

Uint

key_uintN Json Object

Json object:

Key	Value Type	Description
"key"	string or string array	The key name to check if it exists or not. If it is array, it is recognized as nested keys.
"value"	uint	Checking value.
"condition"	string	Checking Condition. "=="/"!="/">"/">="/"<"/"<="

Example:

use case	example configuration
Value of key "log_level" should be match 3	key_uint0 {"key":"log_level","condition","==", "value":3}
Value of key "log_level" should be greater than 3	key_uint0 {"key":"log_level","condition",">", "value":3}

Double

key_doubleN Json Object

Json object:

Key	Value Type	Description
"key"	string or string array	The key name to check if it exists or not. If it is array, it is recognized as nested keys.
"value"	double	Checking value.
"condition"	string	Checking Condition. "=="/"!="/">"/">="/"<"/"<="

Example:

use case	example configuration
Value of key "degree" should be match 27.3	key_double0 {"key":"degree","condition","==", "value":27.3}
Value of key "degree" should be greater than 27.3	key_double0 {"key":"degree","condition",">", "value":27.3}
