"""smoke
|
|
Runs a smoke test of the monitoring installation on mini-mon to ensure
|
|
the components (other than the UI) are functioning. The code tests these
|
|
components:
|
|
1. Agent - ensures metrics are being sent to API
|
|
2. API - ensures alarm definitions can created, listed, etc. Ensure
|
|
metrics and alarms can be queried
|
|
3. CLI - used to talk to the API
|
|
4. Persister - ensures metrics and alarm history has been persisted
|
|
in database because API can query them
|
|
5. Threshold Engine - ensures alarms are created and change state
|
|
6. Notification Engine - ensures email notifications are sent to the
|
|
local system
|
|
This must be run on either the mini-mon VM for the single VM mode or
|
|
on the kafka VM in the multi VM mode.
|
|
|
|
If the tests are to be run in a different environment other than mini-mon,
|
|
the environment variables below can be set and the smoke will use those
|
|
instead of the mini-mon credentials and settings:
|
|
|
|
OS_USERNAME
|
|
OS_PASSWORD
|
|
OS_TENANT_NAME
|
|
OS_AUTH_URL
|
|
MONASCA_API_URL
|
|
|
|
TODO:
|
|
1. Add more logic to give ideas of why a particular step failed, for
|
|
example, alarm did not get created because metrics weren't being
|
|
received
