Does telegraf have any failover mechanism while sending data to influx db ? For my usecase, No data loss is expected. Hence , if influx db is down, I was thinking to write data to file and then was thinking to replay it. Does telegraf provide any such functionality ?

Telegraf has an in memory fifo buffer that will cover small interruptions. You can control the size of this buffer with the `metric_buffer_limit` setting.
