The recovery time is just the same as critical. the retry_interval is
used only during SOFT NON-OK states.

You should most likely check more often. Most people run checks every 5
minutes, if not 1 minutes. Hourly checks means that it can take over an
hour to detect a service failure.

If you absolutely want that, you could use event-handlers to force
service checks upon host recovery, or configure adaptive monitoring to
that services gets checked more often during non-OK states.
