Using the CloudForms SOAP API for daily provision reports

For several reasons, we are currently unable to integrate directly from CloudForms to our CMDB. The current workaround is to send a CSV with the pertinent information to the group responsible for creating CIs in the CMDB. We implemented this originally as part of the Automation workflow – but after talking with this group, they indicated that the volume of individual CSV files would be overwhelming.

Our solution was to develop a job that would gather information from all of the provisioned VMs from the prior day and send a single CSV. I started with the built-in reporting options, but was unable to gather all of the items needed in the report – specifically custom attributes assigned to the VM (both in vCenter and CloudForms). Next, I looked at the REST API. Unfortunately in CloudForms 3.1 (CFME 5.3), the REST API is very sparse. This is something the ManageIQ community has been working on and I expect CloudForms 3.2 (CFME 5.4) will be much better. So I looked at the last remaining choice and implemented something using the SOAP API. In case it’s helpful, here’s what I came up with. I call it with the following cron job:

0 1 * * * root scl enable ruby193 /path/to/script

Here’s the script:

#!/usr/bin/env ruby
# This script will generate a CSV for all VMs provisioned the previous day
# Some fields can be controlled via the /etc/config.ini file
# * organization
# * apiuser
# * apipass
# * apiwsdl
# * notifyfrom
# * notifyaddr
