Usage:

+
+ This program analyzes the cost of Arvados container requests and calculates

+ must be specified.
- 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
- fulfill the container request, together with the machine type and cost of
- each container. At least one uuid must be specified.
+ When the '-output' option is specified, a set of CSV files with cost details
+ will be written to the provided directory. Each file is a CSV report that lists
+ all the containers used to fulfill the container request, together with the
+ machine type and cost of each container.

+ When supplied with the UUID of a collection, it will see if there is a
+ container_request UUID in the properties of the collection, and if so, it
will calculate the cost of that container request and all its children.
- When supplied with a project uuid or when supplied with multiple container
- request or collection uuids, it will create a CSV report for each supplied
- uuid, as well as a CSV file with aggregate cost accounting for all supplied
- uuids. The aggregate cost report takes container reuse into account: if a
- container was reused between several container requests, its cost will only
- be counted once.
+ When supplied with a project UUID or when supplied with multiple container
+ request or collection UUIDs, it will calculate the total cost for all
+ supplied UUIDs.
- 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.
+ When supplied with a 'begin' and 'end' timestamp (format:
+ %s), it will calculate the cost for all top-level container
+ requests whose containers finished during the specified interval.
+
+ The total cost calculation takes container reuse into account: if a container
+ was reused between several container requests, its cost will only be counted
+ once.
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.
- - if a container was run on a preemptible ("spot") instance, the cost data
+ 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.

+
+ - 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.
