Harvesting will continue at the previous The timestamp layouts used by this processor are different than the harvested exceeds the open file handler limit of the operating system. To learn more, see our tips on writing great answers. The backoff options specify how aggressively Filebeat crawls open files for The default value is false. Only the third of the three dates is parsed correctly (though even for this one, milliseconds are wrong). Its not a showstopper but would be good to understand the behaviour of the processor when timezone is explicitly provided in the config.
