Description Chris Duryee 2017-06-13 19:13:54 UTC
Description of problem:

A couple of users have expressed interest in a "host list only" API. This would be useful when scripting and looping over lots of hosts. If it took the same params as the existing /hosts api but returned only the host ID and hostname, that would be ideal.

There are a performance issues with the existing /hosts API call that are being addressed[1]; however even if it was lightning fast, a more minimal result set is still useful for scripting.

This is similar to Spacewalk's listActiveSystems call[2] which does not return system details. The RFE came about from users with spacewalk scripts that run much slower after porting to Katello.

Comment 1 Chris Duryee 2017-06-13 19:18:28 UTC
The listActiveSystems call takes approximately 2 sec for 2K hosts. This new API would need similar performance, at least under 10 seconds for 5K hosts.
