# Wavefront Django SDK
This SDK provides support for reporting out of the box metric, histograms and tracing from your Django based application. That data is reported to Wavefront via proxy or direct ingestion. That data will help you understand how your application is performing in production.
## Install
```bash
pip install wavefront_django_sdk_python
```
## Usage
Configure *settings.py* of your application to install Django SDK as follows:
```python
# setting.py
from wavefront_pyformance.wavefront_reporter import WavefrontDirectReporter, WavefrontProxyReporter
from wavefront_sdk.common import ApplicationTags
from wavefront_django_sdk import DjangoTracing
from wavefront_opentracing_sdk import reporting, WavefrontTracer
INSTALLED_APPS = [
'...',
'wavefront_django_sdk',
'...'
]
MIDDLEWARE = [
'wavefront_django_sdk.middleware.WavefrontMiddleware',
'...'
]
SOURCE = "{SOURCE}"
APPLICATION_TAGS = ApplicationTags(
application="{APP_NAME}",
service="{SERVICE_NAME}",
cluster="{CLUSTER_NAME}", # Optional
shard="{SHARD_NAME}," , # Optional
custom_tags=[("location", "Oregon"), ("env", "Staging")] # Optional
)
# Sending data via Direct Ingestion
WF_REPORTER = WavefrontDirectReporter(
server="{ADDRESS}",
token="{TOKEN}",
reporting_interval=5, # Optional, default value is 10 secs
source=SOURCE,
tags={"application": APPLICATION_TAGS.application}
).report_minute_distribution()
# Or, Sending data via Proxy
WF_REPORTER = WavefrontProxyReporter(
host="{HOST}",
port=2878, # Optional, Wavefront Proxy running on 2878 by default
reporting_interval=5, # Optional, default value is 10 secs
source=SOURCE,
tags={"application": APPLICATION_TAGS.application}
).report_minute_distribution()
span_reporter = reporting.WavefrontSpanReporter(
client=WF_REPORTER.wavefront_client,
source=SOURCE,
)
OPENTRACING_TRACE_ALL = True # Optional, default value is False
OPENTRACING_TRACING = DjangoTracing(WavefrontTracer(
reporter=span_reporter, application_tags=APPLICATION_TAGS))
```
## Out of the box metrics and histograms for your Django based application.
Assume you have the following API in your Django Application:
```python
# urls.py
from django.urls import path
from . import views
urlpatterns = [
path('style//make', views.make_shirts, name="style/{id}/make")
]
# view.py
from django.http import HttpResponse
def make_shirts(request, id):
return HttpResponse("completed", status=200)
```
