Hello , How can I know the start time and the latest time coming of data of all index .
meaning that when was the first time data came in that index and when is the latest time data have came in that index.
Do you really want to know the times in the entire index? If so, tstats is usually the way to go.
| tstats min(_time) as start max(_time) as end where index=myindex
| fieldformat start = strftime(start, "%F %T")
| fieldformat end = strftime(end, "%F %T")
Something like that.
Thank You for your reply , but I want this information for all indexes at once with their respective names is that possible?
This is where you need to be extra diligent in problem statement. Yes, it is doable but volunteers are not mind readers.
| tstats min(_time) as start max(_time) as end where index=* by index
| fieldformat start = strftime(start, "%F %T")
| fieldformat end = strftime(end, "%F %T")
