  • Generate UCA data
  • Convert raw data in CSV form to UCA JSON format

Prerequisites

  • Tested on MacOS, should probably run on Linux in general
  • Python 3.9 or newer
  • pipx or your favorite method of installing packages from PyPi. Have you considered pipx?

Installation

  $ pipx install cloudzero-uca-tools

Quick Starts

General Usage

CloudZero UCA tools exist to produce UCA events that can then be transmitted to the CloudZero API for analysis and processing. To use the CloudZero API, you should first obtain an API key from https://app.cloudzero.com/organization/api-keys

$ uca
Usage: uca [OPTIONS] COMMAND [ARGS]...

  CloudZero Unit Cost Analytics Toolkit

Options:
  --version                 Show the version and exit.
  -c, --configuration TEXT  UCA configuration file (JSON)
  -dry, --dry-run           Perform a dry run, read and transform the data but
                            do not send it to the API. Sample events will be output to the screen
  -k, --api-key TEXT        API Key to use
  --help                    Show this message and exit.

Commands:
  convert
  transmit
  generate

Basic Configuration

A configuration file is typically required to define how UCA telemetry is to be created, converted or transmitted. The following is a minimal configuration file for transmitting data to the CloudZero API (if you don't want to specify the API on the command line, otherwise no configuration file is required for transmit). If you wish to use generate or convert however a configuration file is required.

{
  "version": "1",                               
  "settings": {
    "api_key": "<YOUR API KEY HERE>"
  }
}

# API Key can also be provided at runtime via the CLI. Get an API key at https://app.cloudzero.com/organization/api-keys

Each command has its own set of command line options that will need to be provided as well

Transmit

transmit allows you send UCA data directly to the CloudZero API without having to write code. To use transmit you prepare in advance an ND-JSON formatted input file which contains one or more correctly formatted JSON UCA records as input.

Help

$ uca transmit --help
Usage: uca transmit [OPTIONS]

Options:
  -d, --data TEXT       Source data, in text or gzip + text format, supports
                        file:// or s3:// paths  [required]
  -o, --output TEXT     Instead of sending events to the API, write
                        events to an output file (note: will overwrite file if it exists)
  -t, --transform TEXT  Optional transformation script using jq
                        (https://stedolan.github.io/jq/). Used when the source
                        data needs modification or cleanup. See README.md for
                        usage instructions
  --help                Show this message and exit.

input data

Your input data must be a valid ND-JSON document which can be either a text or gzip file, consisting of one JSON record per line.

For example:

 {'timestamp': '2021-03-22 00:00:00+00:00', 'granularity': 'DAILY', 'element-name': 'StateEx', 'filter': {"custom:Environment": ["Production"]}, 'telemetry-stream': 'test-data', 'value': '40.0000'} 
 {'timestamp': '2021-04-01 00:00:00+00:00', 'granularity': 'DAILY', 'element-name': 'Hooli', 'filter': {"custom:Environment": ["Production"]}, 'telemetry-stream': 'test-data', 'value': '23.0000'}

Using an optional JQ transform

You can optionally provide a JQ script to transform the source data on the fly before transmission. This is helpful when you have minor or even major changes you want to make to the data quickly, and it would be more complicated or impossible to alter the input data (for example an existing system is producing UCA data in an older format).

Example JQ Script

The following script requires the id field to be present (records missing this field will be skipped), followed by setting the target field using a metadata and cost-context field, followed by setting the cost-context to a constant value and then deleting the metadata and uca fields

select(.id != "")
| .filter = {"tag:environment": [.metadata.environment], "tag:feature": [".metadata.feature"] }
| del(.metadata, .uca)
Example Input before JQ transform:
{
  "uca": "v1.5",
  "timestamp": "2021-05-25 13:00:00+0000",
  "granularity": "HOURLY",
  "element-name": "frank",
  "telemetry-stream": "test-data",
  "value": "1073641",
  "metadata": {
    "environment": "production",
    "feature": "rosebud"
  }
}
Example Transformed Output after JQ transform:
{
  "timestamp": "2021-05-25 13:00:00",
  "granularity": "HOURLY",
  "id": "frank",
  "filter": {
    "tag:environment": ["production"],
    "tag:feature": ["rosebud"]
  },
  "telemetry-stream": "Cost-Per-Customer",
  "value": "1073641"
}

Convert

convert allows you to convert raw data in CSV format to UCA JSON format. To use convert you prepare in advance a CSV file of the raw unit cost data you wish to convert and then define the mapping of the CSV columns to UCA fields in a configuration file.

Help

Examples

Convert raw data from data-file.csv into UCA JSON format using a config-file.json as configuration, and write to output-file.json

$ uca convert -d data-file.csv -c config-file.json -o output-file.json

Generate

generate will create UCA data over a defined time period based on rules and source data (CSV) that you define. Rules enable you to define how the data is to be generated based on the provided source data and can be used to create static allocations, dynamic allocations, or even random allocations that can be used to verify system operation or facilitate a demonstration.

  --help             Show this message and exit.                               [optional]

Examples

Generate UCA data between 2021-03-13 and 2021-04-07 using data/configuration.json and data/data.csv as input. Performs only a dry run and do not send the results to the CloudZero API

$ uca generate -s 2021-03-13 -e 2021-04-07 -c data/configuration.json -d data/data.csv --dry-run

Generate UCA data using data/configuration.json and data/data.csv (which must contain a timestamp column) as input. Performs only a dry run and do not send the results to the CloudZero API

$ uca generate -s 2021-03-13 -e 2021-04-07 -c data/configuration.json -d data/data.csv --dry-run

Configuration File

The generate command requires a UCA template definition and specific settings that should be applied when generating data. You can learn more about the UCA format and our UCA Telemetry API here.

{
  "version": "1",                               # can be anything you want that helps you keep track of things
  "template": {
    "timestamp": "$timestamp",                  # Timestamp will be replaced automatically or from the input data source
    "granularity": "DAILY",                     # Granularity can be HOURLY, DAILY or MONTHLY. See notes below for usage
    "element-name": "$element_name",            # Will be replaced using data from your data CSV
    "filter": {},                               # Use a filter to map spend to a combination of tags, dimensions, accounts, etc...
    "telemetry-stream": "test-data",            # Unique name for this telemetry stream          
    "value": "$value"                           # Will be replaced using generated data or data from your data CSV
  },
  "settings": {
    "generate": {
      "mode": "exact",                          # Can be `exact`, `random`, `jitter` or `allocation`
      "jitter": 15,                             # if mode is jitter, defines the +/- random range to applie to the $value
      "allocation": 1000                        # if mode is allocation, defines the total amount to be allocated across elements in your data file
      "precision": 4                            # The number of desired decimal places. If not provided, the default is 4
    },
    "api_key": "<YOUR API KEY HERE>"            # Also can be provided at runtime via the CLI. Get an API key at https://app.cloudzero.com/organization/api-keys
  }
}
A note on using MONTHLY granularity.

MONTHLY is a special (non-standard) granularity that can only be used with the UCA toolkit. MONTHLY will expand the input data over the year and month provided to all possible days in a given month to create DAILY UCA telemetry.

For example if you have this input data:

 element_name,timestamp,value
 "SuperDogs, Inc",2022-10-1,8
 "CoolCats, LLC",2022-10-1,229

This will expand to 61 events, 31 for "SuperDogs, Inc" and 31 for "CoolCats, LLC" (31 days in October)

Data CSV

The data CSV defines the input data you wish to feed into the template to produce matching UCA records for all rows in your data CSV for each hour or day as defined. The following example has 13 "customers" and can be used as input for all configuration modes (exact, random, jitter, or allocation).

    element_name,value,allocation
    Sunbank,37,8.5574
    SoftwareCorp,17,0.4091
    "Parts, Inc.",140,10.9955
    Transport Co.,25,6.3033
    "WeShipit, Inc.",124,23.7549
    CapitalTwo,90,1.5231
    Bank of Sokovia,43,0.1198
    Makers,9,1.0767
    StateEx,40,3.5057
    Flitter,15,22.9554
    Pets2you,78,6.3358
    Hooli,23,4.3294
    Massive Dynamic,42,10.1339

Example output

Using the exact configuration above, this data will produce UCA events similar to the following:

{'timestamp': '2021-03-22 00:00:00+00:00', 'granularity': 'DAILY', 'element-name': 'StateEx', 'filter': {}, 'telemetry-stream': 'test-data', 'value': '40.0000'}
{'timestamp': '2021-04-01 00:00:00+00:00', 'granularity': 'DAILY', 'element-name': 'Hooli', 'filter': {}, 'telemetry-stream': 'test-data', 'value': '23.0000'}
{'timestamp': '2021-04-01 00:00:00+00:00', 'granularity': 'DAILY', 'element-name': 'Sunbank', 'filter': {}, 'telemetry-stream': 'test-data', 'value': '37.0000'}
{'timestamp': '2021-04-06 00:00:00+00:00', 'granularity': 'DAILY', 'element-name': 'Transport Co.', 'filter': {}, 'telemetry-stream': 'test-data', 'value': '25.0000'}
{'timestamp': '2021-03-19 00:00:00+00:00', 'granularity': 'DAILY', 'element-name': 'StateEx', 'filter': {}, 'telemetry-stream': 'test-data', 'value': '40.0000'}

Testing/Developing

First create a virtual environment of your choice, and activate it. Then, install UCA Toolkit for local development:

python -m pip install --editable .

Run the following commands if you had previously installed it using pip or pipx:

  1. Uninstall uca (e.g. pipx uninstall cloudzero-uca-tools)
  2. Create a Virtualenv for your uca development
  3. Enter your virtualenv and install all of the necessary dependencies by running make init
  4. Finally, configure uca for use in your environment using pip install -e .
  5. Once that is done, the uca cli will be available in your shell (you may or may not need to restart your shell).
