newrelic-telemetry-sdk-python provides a Python library for sending data into New Relic using the Python urllib3 library.

See dimensional metrics, events, logs, and spans/traces in New Relic, without having to use an agent!

To start, the newrelic-telemetry-sdk package must be installed. To install through pip:

$ pip install newrelic-telemetry-sdk

If that fails, download the library from its GitHub page and install it using:

$ python setup.py install

There are 3 different types of metrics:

• GaugeMetric
• CountMetric
• SummaryMetric

The example code assumes you've set the following environment variables:

• NEW_RELIC_LICENSE_KEY

import os
import time
from newrelic_telemetry_sdk import GaugeMetric, CountMetric, SummaryMetric, MetricClient

metric_client = MetricClient(os.environ["NEW_RELIC_LICENSE_KEY"])

temperature = GaugeMetric("temperature", 78.6, {"units": "Farenheit"})

# Record that there have been 5 errors in the last 2 seconds
errors = CountMetric(name="errors", value=5, interval_ms=2000)

# Record a summary of 10 response times over the last 2 seconds
summary = SummaryMetric(
    "responses", count=10, min=0.2, max=0.5, sum=4.7, interval_ms=2000
)

batch = [temperature, errors, summary]
response = metric_client.send_batch(batch)
response.raise_for_status()
print("Sent metrics successfully!")

Events represent a record of something that has occurred on a system being monitored. The example code assumes you've set the following environment variables:

• NEW_RELIC_LICENSE_KEY

import os
import time
from newrelic_telemetry_sdk import Event, EventClient

# Record that a rate limit has been applied to an endpoint for an account
event = Event(
    "RateLimit", {"path": "/v1/endpoint", "accountId": 1000, "rejectRatio": 0.1}
)

event_client = EventClient(os.environ["NEW_RELIC_LICENSE_KEY"])
response = event_client.send(event)
response.raise_for_status()
print("Event sent successfully!")

Log messages are generated by applications, usually via the Python logging module. These messages are used to audit and diagnose issues with an operating application. The example code assumes you've set the following environment variables:

• NEW_RELIC_LICENSE_KEY

import os

from newrelic_telemetry_sdk import Log, LogClient

log = Log("Hello World!")

log_client = LogClient(os.environ["NEW_RELIC_LICENSE_KEY"])
response = log_client.send(log)
response.raise_for_status()
print("Log sent successfully!")

Spans provide an easy way to time components of your code. The example code assumes you've set the following environment variables:

• NEW_RELIC_LICENSE_KEY

import os
import time
from newrelic_telemetry_sdk import Span, SpanClient

with Span(name="sleep") as span:
    time.sleep(0.5)

span_client = SpanClient(os.environ["NEW_RELIC_LICENSE_KEY"])
response = span_client.send(span)
response.raise_for_status()
print("Span sleep sent successfully!")

Tips on how to find and query your data in New Relic:

• Find metric data
• Find event data
• Find log data
• Find trace/span data

For general querying information, see:

• Query New Relic data
• Intro to NRQL

The New Relic Telemetry APIs are rate limited. Please reference the documentation for New Relic Metrics API and New Relic Trace API requirements and limits on the specifics of the rate limits.
