Hi, I'm sort of new to ES and currently evaluating how well it will work for storing and querying our log data. I installed Marvel and it worked fine for a while but now I'm suddenly getting weird errors and the index stats are gone from Kibana: [2014-05-09 13:35:43,035][ERROR][marvel.agent.exporter] [Bushmaster] create failure (index:[.marvel-2014.05.09] type: [index\_stats]): MapperParsingException[failed to parse [index]]; nested: MapperParsingException[failed to parse date field [.marvel-2014.05.08], tried both date format [dateOptionalTime], and timestamp number with locale []]; nested: IllegalArgumentException[Invalid format: ".marvel-2014.05.08"]; [2014-05-09 13:35:43,037][ERROR][marvel.agent.exporter] [Bushmaster] create failure (index:[.marvel-2014.05.09] type: [index\_stats]): MapperParsingException[failed to parse [index]]; nested: MapperParsingException[failed to parse date field [.marvel-2014.05.09], tried both date format [dateOptionalTime], and timestamp number with locale []]; nested: IllegalArgumentException[Invalid format: ".marvel-2014.05.09"]; I created a gist detailing the steps I took so far trying to understand/debug what's going on. While debugging, I realized that I'm unable to recreate a marvel index with the same mapping that it "normally" has (either created by marvel or by ES automapping). I detailed this in the gist, too: > Since I didn't temper with Marvel indices to begin with, I don't really see how it suddenly could've gone wrong other than because of a bug. Any hints are appreciated. Regards, Chris -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
