-# Design
-
-Utapi tracks metrics of a service's usage. Metrics provided by Utapi include the
-number of incoming and outgoing bytes, the number of objects being stored, the
-storage utilized in bytes, and a count of operations performed on a service's
-resources. Operations supported by Utapi include APIs offered by Scality's [S3
-Server](https://github.com/scality/S3). Metrics can be retrieved for a given
-time range in a service's history.
-
-## Time Range
-
-Utapi offers metrics for a time range provided by the user. For example, Utapi
-allows a user to view all actions that have occurred over the course of a
-particular month, week, or day. Time ranges are customizable up to a precision
-of fifteen minutes.
-
-Note: A time range precision of less than fifteen minutes can be supported as a
-feature request and could be set as a configurable option.
-
-### Timestamps
-
-Metrics provided by Utapi are set to the latest fifteen minute interval (i.e.,
-00:00:00, 00:15:00, 00:30:00, or 00:45:00). For example, if a user creates a
-bucket at 06:15:01, the operation will have a timestamp of 06:15:00. All
-timestamps are then formatted as a UNIX epoch expressed in milliseconds. During
-a listing of metrics, then, we can know that this operation occurred sometime
-between 06:15:00 and 06:29:59.
-
-#### Example
-
-| current time | timestamp | UNIX epoch timestamp |
-|--------------|-----------|----------------------|
-| 06:15:01     | 06:15:00  | 1483280100000        |
-| 06:29:59     | 06:15:00  | 1483280100000        |
-| 06:31:00     | 06:30:00  | 1483281000000        |
-| 07:01:00     | 07:00:00  | 1483282800000        |
-
-![timestamp graphic](res/timestamp-graphic.png)
-
-### Data Storage
-
-Utapi uses Redis as a database for storage of its metrics values. Accordingly,
-it uses three different Redis data types: Sorted Sets, Strings, and Lists. This
-document describes how these three data types are used by Utapi. For further
-information on data types see the Redis
-[documentation](https://redis.io/topics/data-types).
-
-#### Sorted Sets
-
-The Redis keys storing metrics for the number of objects and the storage
-utilized are recorded with a Sorted Set data type. We use this data type to
-associate the value of the key with its timestamp (in Redis terminology, a
-score). In this way, these two metrics hold *stateful* data. That is, the key's
-value represents the state of a metric at that point in history.
-
-With a Sorted Set, then, we can create a list of values ordered by their
-timestamp. This ordered nature is especially useful for Utapi during a listing
-of metrics, as it allows for speedy retrieval of the nearest starting and ending
-values.
-
-#### Strings
-
-The Redis keys storing metrics for incoming bytes, outgoing bytes, and all S3
-operations (e.g., 'CreateBucket', 'PutObject', etc.) are recorded with a String
-data type.
-
-Moreover, there are also global counters associated with metrics for the number
-of objects and the storage utilized. Such counters are updated during any
-applicable operation. For example, when uploading or deleting an object, the
-counter for the number of objects increments or decrements, respectively. These
-counters are used internally by Sorted Sets to record the state (the storage
-used and the number of objects) at a particular point in time.
-
-#### Lists
-
-Redis keys storing cached metrics use a List data type, where each List element
-is a string containing information from the original request. This datatype is
-used by a component named UtapiReplay that pushes any metrics stored in the List
-every five minutes, by default.
-
-#### Example
-
-Steps occurring during a successful 'PutObject' request:
-
-1. If the new object overwrites a pre-existing object, the counter for the
-    number of objects remains unchanged. Otherwise it increments by one.
-
-2. If the new object overwrites a pre-existing object, the counter for the
-    storage utilized increments by the difference between the byte size of the
-    object and byte size of the object being overwritten. Otherwise, it
-    increments by the byte size of the new object.
-
-3. The metric for the incoming bytes increments by the byte size of the new
-    object.
-
-4. The metric for the 'PutObject' operation increments by one.
-
-5. The Sorted Set keys (the storage used and the number of objects) are updated
-    to the value of their respective counter.
-
-If a connection to the Redis datastore cannot be made, metrics from the original
-request to Utapi are pushed to a local Redis cache to be retried at a later
-time.
-
-### Schema Keyspace
-
-The key created for each metric expresses a hierarchy of the data stored by that
-key. It expresses the service, resource type, the resource, and the metric value
-being stored by the key. These levels are divided by a colon.
-
-```
-<service>:<resourcetype>:<resource>:<metric>
-```
-
-`<service>` The service that the metric belongs to (for example, 's3').
-
-`<resourcetype>` The type of resource being accessed (for example, 'buckets'
-or 'accounts').
-
-`<resource>` The bucket name or account ID (for example, 'foo-bucket').
-
-`<metric>` The metric to get values for (for example, 'storageUtilized').
-
-Thus, a key storing the storage utilized by 'foo-bucket' in 's3' would be:
-
-```
-s3:buckets:foo-bucket:storageUtilized
-```
-
-#### Timestamped Keys
-
-Metrics for S3 operations create keys that generally follow the same pattern as
-above. However, they also include the timestamp at which the operation occurred.
-For example, the key storing the count of 'PutObject' operations `foo-bucket` on
-January 01 2016 00:01:00 (where `1451635200000` is the UNIX epoch timestamp of
-the operation):
-
-```
-s3:buckets:1451635200000:foo-bucket:PutObject
-```
-
-#### Local Redis Cache Key
-
-Metrics of operations pushed by S3 that are unsuccessfully recorded as schema
-keys in the Redis datastore (for example, in the case of a failed connection)
-are stored in a local Redis cache. For example, the key storing cached metrics
-of S3 operations:
-
-```
-s3:utapireplay
-```
-
-The value of the the local Redis cache key is list of JSON strings, where each
-string contains the parameters and timestamp of an unsuccessful `pushMetric`
-call. For example, a string storing metrics for a 'PutObject' operation:
-
-```
-"{\"action\":\"putObject\",\"reqUid\":\"3d534b1511e5630e68f0\",\"params\":{\"bucket\":\"foo-bucket\",\"newByteLength\":1024,\"oldByteLength\":null},\"timestamp\":1451635200000}"
-```
-
-### redis-cli
-
-Note: Using blocking calls (for example, `KEYS *`) with a Redis client during
-production will temporarily block other calls to the Redis Server by Utapi.
-
-Access the storage utilized for the latest fifteen minute time interval using
-the command line interface of Redis, `redis-cli` (see Redis
-[documentation](https://redis.io/topics/rediscli)):
-
-```
-ZRANGE s3:buckets:foo-bucket:storageUtilized -1 -1 WITHSCORES
-```
-
-The `WITHSCORES` option in the above command will return the timestamp for each
-value.
-
-Access the value stored by a key that is a String data type:
-
-```
-GET s3:buckets:1451635200000:foo-bucket:PutObject
-```

-## Design
-
-Please refer to the [design](/DESIGN.md) for more information.
-
-## Server
-
-To run the server:
-
-```
-npm start
-```
-
-## Client
-
-The module exposes a client, named UtapiClient. Projects can use this client to
-push metrics directly to the underlying datastore (Redis) without the need of an
-extra HTTP request to Utapi.
-
-```js
-const { UtapiClient } = require('utapi');
-
-const config = {
-    redis: {
-        host: '127.0.0.1',
-        port: 6379
-    },
-    localCache: {
-        host: '127.0.0.1',
-        port: 6379
-    }
-}
-const c = new UtapiClient(config);
-
-// The second argument to `pushMetric` is a hexadecimal string Request Unique
-// Identifier used for logging.
-c.pushMetric('createBucket', '3d534b1511e5630e68f0', { bucket: 'demo' });
-
-c.pushMetric('putObject', '3d534b1511e5630e68f0', {
-    bucket: 'demo',
-    newByteLength: 1024,
-    oldByteLength: null,
-});
-
-c.pushMetric('putObject', '3d534b1511e5630e68f0', {
-    bucket: 'demo',
-    newByteLength: 1024,
-    oldByteLength: 256,
-});
-
-c.pushMetric('multiObjectDelete', '3d534b1511e5630e68f0', {
-    bucket: 'demo',
-    byteLength: 1024,
-    numberOfObjects: 999,
-});
-```
-
-If an error occurs during a `pushMetric` call and the client is unable to record
-metrics in the underlying datastore, metric data is instead stored in a local
-Redis cache. Utapi attempts to push these cached metrics (every five minutes, by
-default) using a component named UtapiReplay. If the `pushMetric` call initiated
-by UtapiReplay fails, the metric is reinserted into the local Redis cache. The
-particularities of this behavior are configurable. For further information, see
-[design](/DESIGN.md).
-
-## Listing Metrics with Utapi
-
-To make a successful request to Utapi you would need
-
- 1. [IAM user with a policy giving access to Utapi](#iam-user-with-a-policy-giving-access-to-utapi)
- 2. [Sign request with Auth V4](#signing-request-with-auth-v4)
-
-### IAM user with a policy giving access to Utapi
-
-Note: The examples here use AWS CLI but any AWS SDK is capable of these actions.
-
-**endpoint-url:** This would be `https://<host>:<port>` where your Identity(IAM)
-Server is running.
-
-1. Create an IAM user
-
-    ```
-    aws iam --endpoint-url <endpoint> create-user --user-name <user-name>
-    ```
-
-2. Create access key for the user
-
-    ```
-    aws iam --endpoint-url <endpoint> create-access-key --user-name <user-name>
-    ```
-
-3. Define a managed IAM policy
-
-    sample utapi policy
-
-    ```json
-    cat - > utapipolicy.json <<EOF
-    {
-        "Version": "2012-10-17",
-        "Statement": [
-            {
-                "Sid": "utapiMetrics",
-                "Action": [ "utapi:ListMetrics" ],
-                "Effect": "Allow",
-                "Resource": [
-                    "arn:scality:utapi::012345678901:buckets/*",
-                    "arn:scality:utapi::012345678901:accounts/*",
-                    "arn:scality:utapi::012345678901:users/*",
-                ]
-            }
-        ]
-    }
-    EOF
-    ```
-
-    In the above sample, the `Resource` property includes a series of Amazon
-    Resource Names (ARNs) used to define which resources the policy applies to.
-    Thus the sample policy applies to a user with an account ID '012345678901',
-    and grants access to metrics at the levels 'buckets', 'accounts', and
-    'users'.
-
-    The account ID of the ARN can also be omitted, allowing any account to
-    access metrics for those resources. As an example, we can extend the above
-    sample policy to allow any account to access metrics at the level 'service':
-
-    ```json
-    ...
-    "Resource": [
-        "arn:scality:utapi::012345678901:buckets/*",
-        "arn:scality:utapi::012345678901:accounts/*",
-        "arn:scality:utapi::012345678901:users/*",
-        "arn:scality:utapi:::service/*",
-    ]
-    ...
-    ```
-
-    The omission of a metric level denies a user access to all resources at that
-    level. For example, we can allow access to metrics only at the level
-    'buckets':
-
-    ```json
-    ...
-    "Resource": ["arn:scality:utapi::012345678901:buckets/*"]
-    ...
-    ```
-
-    Further, access may be limited to specific resources within a metric level.
-    For example, we can allow access to metrics only for a bucket  'foo':
-
-    ```json
-    ...
-    "Resource": ["arn:scality:utapi::012345678901:buckets/foo"]
-    ...
-    ```
-
-    Or allow access to metrics for the bucket 'foo' for any user:
-
-    ```json
-    ...
-    "Resource": ["arn:scality:utapi:::buckets/foo"]
-    ...
-    ```
-
-4. Create a managed IAM policy
-
-    Once your IAM policy is defined, create the policy using the following
-    command.
-
-    ```
-    aws iam --endpoint-url <endpoint> create-policy --policy-name utapipolicy \
-     --policy-document file://utapipolicy.json
-    ```
-
-    A sample output of the above command would look like
-
-    ```json
-    {
-        "Policy": {
-            "PolicyName": "utapipolicy",
-            "CreateDate": "2017-06-01T19:31:18.620Z",
-            "AttachmentCount": 0,
-            "IsAttachable": true,
-            "PolicyId": "ZXR6A36LTYANPAI7NJ5UV",
-            "DefaultVersionId": "v1",
-            "Path": "/",
-            "Arn": "arn:aws:iam::0123456789012:policy/utapipolicy",
-            "UpdateDate": "2017-06-01T19:31:18.620Z"
-        }
-    }
-    ```
-
-    The arn property of the response, which we call `<policy arn>`, will be used
-    in the next step to attach the policy to the user.
-
-5. Attach user to the managed policy
-
-    ```
-    aws --endpoint-url <endpoint> iam  attach-user-policy --user-name
-    <user-name> --policy-arn <policy arn>
-    ```
-
-Now the user has access to ListMetrics request in Utapi on all buckets.
-
-### Signing request with Auth V4
-
-There are two options here.
-
-You can generate V4 signature using AWS SDKs or the node module aws4. See the
-following urls for reference.
-
-* http://docs.aws.amazon.com/general/latest/gr/sigv4_signing.html
-* http://docs.aws.amazon.com/general/latest/gr/sigv4-signed-request-examples.html
-* https://github.com/mhart/aws4
-
-You may also view examples making a request with Auth V4 using various languages
-and AWS SDKs [here](/examples).
-
-Alternatively, you can use a nifty command line tool available in Scality's
-CloudServer.
-
-You can git clone the CloudServer repo from here
-https://github.com/scality/cloudserver and follow the instructions in the README
-to install the dependencies.
-
-If you have CloudServer running inside a docker container you can docker exec
-into the CloudServer container as
-
-```
-docker exec -it <container-id> bash
-```
-
-and then run the command
-
-```
-node bin/list_metrics
-```
-
-It will generate the following output listing available options.
-
-```
-Usage: list_metrics [options]
-
-  Options:
-
-    -h, --help                    output usage information
-    -V, --version                 output the version number
-    -a, --access-key <accessKey>  Access key id
-    -k, --secret-key <secretKey>  Secret access key
-    -m, --metric <metric>         Metric type
-    --buckets <buckets>           Name of bucket(s) with a comma separator if
-                                  more than one
-    --accounts <accounts>         Account ID(s) with a comma separator if more
-                                  than one
-    --users <users>               User ID(s) with a comma separator if more than
-                                  one
-    --service <service>           Name of service
-    -s, --start <start>           Start of time range
-    -r, --recent                  List metrics including the previous and
-                                  current 15 minute interval
-    -e --end <end>                End of time range
-    -h, --host <host>             Host of the server
-    -p, --port <port>             Port of the server
-    --ssl                         Enable ssl
-    -v, --verbose
-```
-
-An example call to list metrics for a bucket `demo` to Utapi in a https enabled
-deployment would be
-
-```
-node bin/list_metrics --metric buckets --buckets demo --start 1476231300000
---end 1476233099999 -a myAccessKey -k mySecretKey -h 127.0.0.1 -p 8100 --ssl
-```
-
-Both start and end times are time expressed as UNIX epoch timestamps **expressed
-in milliseconds**.
-
-Keep in mind, since Utapi metrics are normalized to the nearest 15 min.
-interval, start time and end time need to be in the specific format as follows.
-
-#### Start time
-
-Start time needs to be normalized to the nearest 15 minute interval with seconds
-and milliseconds set to 0. So valid start timestamps would look something like
-`09:00:00:000`, `09:15:00:000`, `09:30:00:000` and `09:45:00:000`.
-
-For example
-
-Date: Tue Oct 11 2016 17:35:25 GMT-0700 (PDT)
-
-Unix timestamp (milliseconds): 1476232525320
-
-Here's an example JS method to get a start timestamp
-
-```javascript
-function getStartTimestamp(t) {
-    const time = new Date(t);
-    const minutes = time.getMinutes();
-    const timestamp = time.setMinutes((minutes - minutes % 15), 0, 0);
-    return timestamp;
-}
-```
-
-This would format the start time timestamp to `1476231300000`
-
-#### End time
-
-End time needs to be normalized to the nearest 15 minute end interval with
-seconds and milliseconds set to 59 and 999 respectively. So valid end timestamps
-would look something like `09:14:59:999`, `09:29:59:999`, `09:44:59:999` and
-`09:59:59:999`.
-
-Here's an example JS method to get an end timestamp
-
-```javascript
-function getEndTimestamp(t) {
-    const time = new Date(t);
-    const minutes = time.getMinutes();
-    const timestamp = time.setMinutes((minutes - minutes % 15) + 15, 0, -1);
-    return timestamp;
-}
-```
-
-This would format the end time timestamp to `1476233099999`

-# Utapi Release Plan
-
-## Docker Image Generation
-
-Docker images are hosted on [ghcr.io](https://github.com/orgs/scality/packages).
-Utapi has one namespace there:
-
-* Namespace: ghcr.io/scality/utapi
-
-With every CI build, the CI will push images, tagging the
-content with the developer branch's short SHA-1 commit hash.
-This allows those images to be used by developers, CI builds,
-build chain and so on.
-
-Tagged versions of utapi will be stored in the production namespace.
-
-## How to Pull Docker Images
-
-```sh
-docker pull ghcr.io/scality/utapi:<commit hash>
-docker pull ghcr.io/scality/utapi:<tag>
-```
-
-## Release Process
-
-To release a production image:
-
-* Name the tag for the repository and Docker image.
-
-* Use the `yarn version` command with the same tag to update `package.json`.
-
-* Create a PR and merge the `package.json` change.
-
-* Tag the repository using the same tag.
-
-* [Force a build] using:
-  * A given branch that ideally matches the tag.
-  * The `release` stage.
-  * An extra property with the name `tag` and its value being the actual tag.
-
-[Force a build]:
