Overview ¶
Package logging provides implementations of runtime.LoggingManager.

Constants ¶
const ( // Overall capacity of the log buffer (in raw bytes, memory size will be smaller due to compression). DesiredCapacity = 1048576 // Some logs are tiny, no need to reserve too much memory. InitialCapacity = 16384 // Chunk capacity is the length of each chunk, it should be // big enough for the compression to be efficient. ChunkCapacity = 65536 // Number of zstd-compressed chunks to keep. NumCompressedChunks = (DesiredCapacity / ChunkCapacity) - 1 // Safety gap to avoid buffer overruns, can be lowered as with compression we don't need much. SafetyGap = 1 )
These constants should some day move to config.

Functions ¶
func NewJSONLines ¶
func NewJSONLines(cfg config.LoggingDestination) runtime.LogSender
NewJSONLines returns log sender that sends logs in JSON over TCP (newline-delimited) or UDP (one message per packet).
Types ¶
type CircularBufferLoggingManager ¶
type CircularBufferLoggingManager struct {
// contains filtered or unexported fields
}
CircularBufferLoggingManager implements logging to circular fixed size buffer.
func NewCircularBufferLoggingManager ¶
