storage.local.retention not working as expected

[abhijit...@gmail.com]

I am trying to retain data in prometheus for a period of one hour.

For this I am starting prometheus as given below

prometheus -config.file=prometheus.yml -storage.local.retention=1h

I would expect that data is retained for one hour and any data prior to one hour should be purged.

But it seem that the old data prior to an hour is not removed.

What am I doing wrong?

It takes some time for the storage engine to run through a cleanup cycle.  It's also not exact, as it also has to respect the -storage.local.series-file-shrink-ratio flag (default 0.1).

Thanks for the reply. 
But can I make any changes to any of these flags (or any other  such that I can enforce the one hour retention.
