Types ¶
type Config ¶
type Config struct { // File-specifc Location *SeekInfo // Seek to this location before tailing ReOpen bool // Reopen recreated files (tail -F) MustExist bool // Fail early if the file does not exist Poll bool // Poll for file changes instead of using inotify Pipe bool // Is a named pipe (mkfifo) RateLimiter *ratelimiter.LeakyBucket // Generic IO Follow bool // Continue looking for new lines (tail -f) MaxLineSize int // If non-zero, split longer lines into multiple lines // Logger, when nil, is set to tail.DefaultLogger // To disable logging: set field to tail.DiscardingLogger Logger logger }
Config is used to specify how a file must be tailed.
