Description Andreas Karis 2017-05-12 17:17:44 UTC
Description of problem:
Execution time of /bin/tripleo-ansible-inventory way too high

Version-Release number of selected component (if applicable):
[root@undercloud-4 ~]# rpm -qf /bin/tripleo-ansible-inventory

Actual results:
[stack@undercloud-4 ~]$ time tripleo-ansible-inventory --list
{"overcloud": {"children": ["controller", "compute"], "vars": {"ansible_ssh_user": "heat-admin"}}, "controller": [""], "undercloud": {"hosts": ["localhost"], "vars": {"overcloud_horizon_url": "", "overcloud_admin_password": "dzd8PRdB4TWGGygkCDGdUHrkY", "ansible_connection": "local"}}, "compute": ["", ""]}

real	1m12.398s
user	0m0.779s
sys	0m0.110s

Expected results:
< 1 second execution time on any system

Additional info:
run in a virtual undercloud, however, as this doesn't do anything more than list a few hosts and passwords, it should not take this long

Comment 3 Florian Fuchs 2017-09-05 10:17:18 UTC
There have been several performance improvements to the inventory in Ocata (backported) and Pike.

However, because there are a number of API calls involved when creating the dynamic inventory result, expecting an execution time of < 1s is maybe not realistic. The inventory has a --static-inventory option though which writes the result to a static inventory file. This should help where performance is critical.
