Usage

Please also refer to examples for more detailed usage.

Installation

# Choose the version to install
VERSION=0.4.0
pip install frequenz-client-reporting==$VERSION

Initialize the client

from datetime import datetime

from frequenz.client.common.metric import Metric
from frequenz.client.reporting import ReportingApiClient

# Change server address
SERVICE_ADDRESS = "localhost:4711"
API_KEY = open('api_key.txt').read().strip()
client = ReportingApiClient(service_address=SERVICE_ADDRESS, key=API_KEY)

Query metrics for a single microgrid and component:

data = [
    sample async for sample in
    client.list_single_component_data(
        microgrid_id=1,
        component_id=100,
        metrics=[Metric.AC_ACTIVE_POWER, Metric.AC_REACTIVE_POWER],
        start_dt=datetime.fromisoformat("2024-05-01T00:00:00"),
        end_dt=datetime.fromisoformat("2024-05-02T00:00:00"),
        page_size=10000,
        resolution=1,
    )
]

Query metrics for multiple microgrids and components

# Set the microgrid ID and the component IDs that belong to the microgrid
# Multiple microgrids and components can be queried at once
microgrid_id1 = 1
component_ids1 = [100, 101, 102]
microgrid_id2 = 2
component_ids2 = [200, 201, 202]
microgrid_components = [
    (microgrid_id1, component_ids1),
    (microgrid_id2, component_ids2),
]

data = [
    sample async for sample in
    client.list_microgrid_components_data(
        microgrid_components=microgrid_components,
        metrics=[Metric.AC_ACTIVE_POWER, Metric.AC_REACTIVE_POWER],
        start_dt=datetime.fromisoformat("2024-05-01T00:00:00"),
        end_dt=datetime.fromisoformat("2024-05-02T00:00:00"),
        page_size=10000,
        resolution=1,
    )
]

Optionally convert the data to a pandas DataFrame

import pandas as pd
df = pd.DataFrame(data)
print(df)

Command line client example

The example folder contains a simple client that can be used to query the reporting API from the command line:

python examples/client.py \
    --url localhost:4711 \
    --key=$(<api_key.txt)
    --mid 42 \
    --cid 23 \
    --metrics AC_ACTIVE_POWER AC_REACTIVE_POWER \
    --start 2024-05-01T00:00:00 \
    --end 2024-05-02T00:00:00
