Grafana Foundation SDK – Python
A set of tools, types and builder libraries for building and manipulating Grafana objects in Python.
Installing
python3 -m pip install 'grafana_foundation_sdk==v0.0.21'
Example usage
Building a dashboard
from grafana_foundation_sdk.builders.dashboard import Dashboard, Row
from grafana_foundation_sdk.builders.prometheus import Dataquery as PrometheusQuery
from grafana_foundation_sdk.builders.timeseries import Panel as Timeseries
from grafana_foundation_sdk.cog.encoder import JSONEncoder
from grafana_foundation_sdk.models.common import TimeZoneBrowser
def build_dashboard() -> Dashboard:
builder = (
Dashboard("[TEST] Node Exporter / Raspberry")
.uid("test-dashboard-raspberry")
.tags(["generated", "raspberrypi-node-integration"])
.refresh("1m")
.time("now-30m", "now")
.timezone(TimeZoneBrowser)
.with_row(Row("Overview"))
.with_panel(
Timeseries()
.title("Network Received")
.unit("bps")
.min_val(0)
.with_target(
PrometheusQuery()
.expr('rate(node_network_receive_bytes_total{job="integrations/raspberrypi-node", device!="lo"}[$__rate_interval]) * 8')
.legend_format("{{ device }}")
)
)
)
return builder
if __name__ == '__main__':
dashboard = build_dashboard().build()
encoder = JSONEncoder(sort_keys=True, indent=2)
print(encoder.encode(dashboard))
Unmarshaling a dashboard
import json
from grafana_foundation_sdk.cog.plugins import register_default_plugins
from grafana_foundation_sdk.models.dashboard import Dashboard as DashboardModel
if __name__ == '__main__':
# Required to correctly unmarshal panels and dataqueries
register_default_plugins()
with open("dashboard.json", "r") as f:
decoded_dashboard = DashboardModel.from_json(json.load(f))
print(decoded_dashboard)
Defining a custom query type
While the SDK ships with support for all core datasources and their query types, it can be extended for private/third-party plugins.
To do so, define a type and a builder for the custom query:
# src/customquery.py
from typing import Any, Optional, Self
from grafana_foundation_sdk.cog import variants as cogvariants
from grafana_foundation_sdk.cog import runtime as cogruntime
from grafana_foundation_sdk.cog import builder
class CustomQuery(cogvariants.Dataquery):
# ref_id and hide are expected on all queries
ref_id: Optional[str]
hide: Optional[bool]
# query is specific to the CustomQuery type
query: str
def __init__(self, query: str, ref_id: Optional[str] = None, hide: Optional[bool] = None):
self.query = query
self.ref_id = ref_id
self.hide = hide
def to_json(self) -> dict[str, object]:
payload: dict[str, object] = {
"query": self.query,
}
if self.ref_id is not None:
payload["refId"] = self.ref_id
if self.hide is not None:
payload["hide"] = self.hide
return payload
@classmethod
def from_json(cls, data: dict[str, Any]) -> Self:
args: dict[str, Any] = {}
if "query" in data:
args["query"] = data["query"]
if "refId" in data:
args["ref_id"] = data["refId"]
if "hide" in data:
args["hide"] = data["hide"]
return cls(**args)
def custom_query_variant_config() -> cogruntime.DataqueryConfig:
return cogruntime.DataqueryConfig(
# datasource plugin ID
identifier="custom-query",
from_json_hook=CustomQuery.from_json,
)
class CustomQueryBuilder(builder.Builder[CustomQuery]):
_internal: CustomQuery
def __init__(self, query: str):
self._internal = CustomQuery(query=query)
def build(self) -> CustomQuery:
return self._internal
def ref_id(self, ref_id: str) -> Self:
self._internal.ref_id = ref_id
return self
def hide(self, hide: bool) -> Self:
self._internal.hide = hide
return self
Register the type with cog, and use it as usual to build a dashboard:
from grafana_foundation_sdk.builders.dashboard import Dashboard, Row
from grafana_foundation_sdk.builders.timeseries import Panel as Timeseries
from grafana_foundation_sdk.cog.encoder import JSONEncoder
from grafana_foundation_sdk.cog.plugins import register_default_plugins
from grafana_foundation_sdk.cog.runtime import register_dataquery_variant
from src.customquery import custom_query_variant_config, CustomQueryBuilder
if __name__ == '__main__':
# Required to correctly unmarshal panels and dataqueries
register_default_plugins()
# This lets cog know about the newly created query type and how to unmarshal it.
register_dataquery_variant(custom_query_variant_config())
dashboard = (
Dashboard("Custom query type")
.uid("test-custom-query")
.refresh("1m")
.time("now-30m", "now")
.with_row(Row("Overview"))
.with_panel(
Timeseries()
.title("Sample panel")
.with_target(
CustomQueryBuilder("query here")
)
)
).build()
print(JSONEncoder(sort_keys=True, indent=2).encode(dashboard))
Defining a custom panel type
While the SDK ships with support for all core panels, it can be extended for private/third-party plugins.
To do so, define a type and a builder for the custom panel's options:
# src/custompanel.py
from typing import Any, Self
from grafana_foundation_sdk.cog import builder
from grafana_foundation_sdk.cog import runtime as cogruntime
from grafana_foundation_sdk.builders.dashboard import Panel as PanelBuilder
from grafana_foundation_sdk.models import dashboard
class CustomPanelOptions:
make_beautiful: bool
def __init__(self, make_beautiful: bool = False):
self.make_beautiful = make_beautiful
def to_json(self) -> dict[str, object]:
return {
"makeBeautiful": self.make_beautiful,
}
@classmethod
def from_json(cls, data: dict[str, Any]) -> Self:
args: dict[str, Any] = {}
if "makeBeautiful" in data:
args["make_beautiful"] = data["makeBeautiful"]
return cls(**args)
def custom_panel_variant_config() -> cogruntime.PanelCfgConfig:
return cogruntime.PanelCfgConfig(
# plugin ID
identifier="custom-panel",
options_from_json_hook=CustomPanelOptions.from_json,
)
class CustomPanelBuilder(PanelBuilder, builder.Builder[dashboard.Panel]):
def __init__(self):
super().__init__()
# plugin ID
self._internal.type_val = "custom-panel"
def make_beautiful(self) -> Self:
if self._internal.options is None:
self._internal.options = CustomPanelOptions()
assert isinstance(self._internal.options, CustomPanelOptions)
self._internal.options.make_beautiful = True
return self
Register the type with cog, and use it as usual to build a dashboard:
from grafana_foundation_sdk.builders.dashboard import Dashboard, Row
from grafana_foundation_sdk.cog.encoder import JSONEncoder
from grafana_foundation_sdk.cog.plugins import register_default_plugins
from grafana_foundation_sdk.cog.runtime import register_panelcfg_variant
from src.custompanel import custom_panel_variant_config, CustomPanelBuilder
if __name__ == '__main__':
# Required to correctly unmarshal panels and dataqueries
register_default_plugins()
# This lets cog know about the newly created panel type and how to unmarshal it.
register_panelcfg_variant(custom_panel_variant_config())
dashboard = (
Dashboard("Custom panel type")
.uid("test-custom-panel")
.refresh("1m")
.time("now-30m", "now")
.with_row(Row("Overview"))
.with_panel(
CustomPanelBuilder()
.title("Sample panel")
.make_beautiful()
)
).build()
print(JSONEncoder(sort_keys=True, indent=2).encode(dashboard))
Maturity
The code in this repository should be considered as "public preview". While it is used by Grafana Labs in production, it still is under active development.
