Hi,
I’m having issues with a dynamic inventory script I created for Solar Winds. It’s here, https://github.com/cbabs/solarwinds-ansible-inv. The script seems to work as expected. When I copy to hosts and run with --list seems fine. It takes a few seconds to query the Orion SQL server via rest and return the data. However when I execute “ansible --list-hosts all” it’s very slow. I tried with the dyn inv script as ‘hosts’ and with a static hosts file with the same data. Clearly I don’t understand something.
It’s almost like Ansible is iterating it’s process on each entry instead of reading all the output at once. I’ve read the “Developing Dynamic Inventory Sources” doc three times looking a for something I missed. I don’t get it.
Here are my results:
