Hello, I configure generator input to generate logs and sent them to elasticsearch by logstash. At the beginning of elasticsearch start working, the number of events can reach to 20000 events/sec into es. But over time, it becomes less and less. And on 8:00 everyday When logstash creat a new index into es automaticly, it will repeat this phenomenon. Does somebody know the reason for it? How can I optimize elasticsearch and make it steady index 20000 events/s all the time within a day? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
