This program analyzes the cost of Arvados container requests. For each uuid
supplied, it creates a CSV report that lists all the containers used to
container was reused between several container requests, its cost will only
be counted once.
- To get the node costs, the progam queries the Arvados API for current cost
- data for each node type used. This means that the reported cost always
- reflects the cost data as currently defined in the Arvados API configuration
- file.
-
Caveats:
- - the Arvados API configuration cost data may be out of sync with the cloud
- provider.
- - when generating reports for older container requests, the cost data in the
- Arvados API configuration file may have changed since the container request
- was fulfilled. This program uses the cost data stored at the time of the

execution of the container, stored in the 'node.json' file in its log
- collection.
+ collection. If the cost data was not correctly configured at the time the
+ container was executed, the output from this program will be incorrect.
+
+ - If a container was run on a preemptible ("spot") instance, the cost data
+ reported by this program may be wildly inaccurate, because it does not have
+ access to the spot pricing in effect for the node then the container ran. The
+ UUID report file that is generated when the '-output' option is specified has
+ a column that indicates the preemptible state of the instance that ran the
+ container.
+
+ - This program does not take into account overhead costs like the time spent
+ starting and stopping compute nodes that run containers, the cost of the
+ permanent cloud nodes that provide the Arvados services, the cost of data
+ stored in Arvados, etc.
+
+ - When provided with a project uuid, subprojects will not be considered.
In order to get the data for the uuids supplied, the ARVADOS_API_HOST and
ARVADOS_API_TOKEN environment variables must be set.
