Creating the Databus credentials

Databus credentials are needed to establish secure connections for the Metering V2 service to transmit metrics.

Ensure that you have the following:

A Cloudera user account that can be promoted to Full Administrator role in Cloudera Manager.
Grants to create API keys and Machine Users in Cloudera User Management Service (UMS).

Create a new Machine User by following Creating a machine user in Cloudera.
note
- The particular machine user name is not important but will be needed for the following commands.
- Make sure that the machine user is not deleted, to avoid losing metering events, which is registered by the Metering Events Monitor (MEM) service.

Retrieve the DatabaseUploader role CRN:

cdp iam list-roles | grep “altus:role:DbusUploader”

Update machine user with DatabaseUploader role:

cdp iam assign-machine-user-role --machine-user-name ***USER-NAME-FROM-STEP1*** --role ***CRN-FROM-STEP-2***

Create API Access Keys

cdp iam create-machine-user-access-key --machine-user-name ***USER-NAME-FROM-STEP1***

Record the accessKeyId and the privateKey for use later:

{
    "accessKey": {
        "accessKeyId": "abc",
        "crn": "",
        "actorCrn": "",
        "creationDate": "",
        "status": "ACTIVE",
        "type": "V2"
    },
    "privateKey": "abc"
}

In the CRN value from the JSON in the previous step, record the region and the account number. For example, the Region (us-west-1) and Tenant ID (215d3903-333d-45ae-8824-6a4a85e17e22) are highlighted in the example CRN:
```
crn:altus:iam:***REGION***:***TENANT-ID***:accesskey:***ACCESS-KEY***
```
```
crn:altus:iam:us-west-1:215d3903-333d-45ae-8824-6a4a85e17e22:accesskey:b940b1ef-3ef7-425f-9140-2709990f544c
```
