Set the buffer size for HTTP client when reading responses from Kubernetes API server. The value must be according to the Unit Size specification.
Default: 32k
Set the limit of the buffer size per monitored file. When a buffer needs to be increased (e.g: very long lines), this value is used to restrict how much the memory buffer can grow. If reading a file exceed this limit, the file is removed from the monitored file list. The value must be according to the Unit Size specification.
Default: Buffer_Chunk_Size
Specify the database file to keep track of monitored files and offsets.
sets the journal mode for databases (WAL). Enabling WAL provides higher performance. Note that WAL is not compatible with shared network file systems.
Default: WAL
Specify that the database will be accessed only by Fluent Bit. Enabling this feature helps to increase performance when accessing the database but it restrict any external tool to query the content.

When a message is unstructured (no parser applied), it’s appended as a string under the key name log. This option allows to define an alternative name for that key.
Default: log
Set a limit of memory that Tail plugin can use when appending data to the Engine. If the limit is reach, it will be paused; when the data is flushed it resumes.
If enabled, the plugin will try to discover multiline messages and use the proper parsers to compose the outgoing messages. Note that when this option is enabled the Parser option is not used.
Default: Off
Wait period time in seconds to process queued multiline messages
Default: 4
Specify one or multiple parser definitions to apply to the content. Part of the new Multiline Core support in 1.8
Default: ""
Specify the name of a parser to interpret the entry as a structured message.
Name of the parser that machs the beginning of a multiline message. Note that the regular expression defined in the parser must include a group name (named capture)

Pattern specifying a specific log files or multiple ones through the use of common wildcards.
If enabled, it appends the name of the monitored file as part of the record. The value assigned becomes the key in the map.
For new discovered files on start (without a database offset/position), read the content from the head of the file, not tail.

Default: 60
Specify the number of extra time in seconds to monitor a file once is rotated in case some pending data is flushed.
Default: 5
When a monitored file reach it buffer capacity due to a very long line (Buffer_Max_Size), the default behavior is to stop monitoring that file. Skip_Long_Lines alter that behavior and instruct Fluent Bit to skip long lines and continue processing other lines that fits into the buffer size.
Default: Off
Specify the buffering mechanism to use. It can be memory or filesystem.
Default: memory

Default: On
Buffer_Size (string, optional)
Set the buffer size for HTTP client when reading responses from Kubernetes API server. The value must be according to the Unit Size specification. A value of 0 results in no limit, and the buffer will expand as-needed. Note that if pod specifications exceed the buffer limit, the API response will be discarded when retrieving metadata, and some kubernetes metadata will fail to be injected to the logs. If this value is empty we will set it “0”.
Default: “0”

Configurable TTL for K8s cached metadata. By default, it is set to 0 which means TTL for cache entries is disabled and cache entries are evicted at random when capacity is reached.

When Merge_Log is enabled, the filter tries to assume the log field from the incoming message is a JSON string message and make a structured representation of it at the same level of the log field in the map. Now if Merge_Log_Key is set (a string name), all the new structured fields taken from the original log content are inserted under the new key.
