Tenant statistics example (based on v2 API/DSL)
===============================================
The example shows how Mistral can be used to gather information about
OpenStack tenant. The workbook "tenant_statistics" contains two workflows
that solve the same task: they send an email report containing a number
of virtual machines, number of active virtual machines and number of
networks. Workflow "tenant_statistics_plain" runs runs all its tasks
sequentially one after another. Workflow "tenant_statistics_join" runs
two tasks in parallel to gather tenant metrics, waits their completion
using "join" workflow control and after that sends a report.
To run the example:
1. Load workbook from tenant_statistics.yaml:
mistral workbook-create tenant_statistics.yaml
1. Create input.json file containing workflow input parameters as follows:
{
"to_email": "admin@my_domain.com",
"from_email": "my_address@my_domain.com",
"smtp_server": "smtp.my_domain.com:587",
"smtp_password": "my_password"
}
1. Start workflow:
mistral execution-create tenant_statistics.tenant_statistics_join input.json
1. Using execution id from the previous step wait for completion (workflow SUCCESS state):
mistral execution-get <execution_id>
1. Check email inbox for the expected report.
