Werk #16254 added metric translations for the Windows-style Nagios plug-ins check_ping.exe and check_tcp.exe, but the registration key was not normalized the same way as the lookup key. As a result, the translations never fired:

The rta metric reported by check_ping.exe was rendered in seconds instead of milliseconds (values appeared ~1000× too large).
The time metric reported by check_tcp.exe was not renamed to response_time.

Both translations now apply correctly.
