Export Django logs to Azure AppInsights with OpenCensus - django

Question

I'm following this guidance for Django and Azure. I'm able to get dependancies and requests, but not traces.
I added this to middleware:
'opencensus.ext.django.middleware.OpencensusMiddleware'
Here is the LOGGING and OPENCENSUS portions of settings.py
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'default': {
'format': '%(asctime)s - %(levelname)s - %(processName)s - %(name)s\n%(message)s',
},
},
"handlers": {
"azure": {
"level": "DEBUG",
"class": "opencensus.ext.azure.log_exporter.AzureLogHandler",
"instrumentation_key": assert_env('APPINSIGHTS_INSTRUMENTATIONKEY'),
},
"console": {
"level": "DEBUG",
"class": "logging.StreamHandler",
"formatter": "default",
},
},
"loggers": {
"logger_name": {"handlers": ["azure", "console"]},
},
# For some reason, this is needed or logging doesn't show up in the
# celery log file.
'skyforge.tasks': {
'handlers': ['azure','console'],
'level': assert_env('DJANGO_LOG_LEVEL'),
},
}
OPENCENSUS = {
'TRACE': {
'SAMPLER': 'opencensus.trace.samplers.ProbabilitySampler(rate=1)',
'EXPORTER': '''opencensus.ext.azure.trace_exporter.AzureExporter(
service_name='skyforge'
)'''
#Assumes Environmental Variable 'APPINSIGHTS_INSTRUMENTATIONKEY'
}
}
Any guidance on where to look for why no trace logs. The django-critical and django-tasks are still going to the console.

Answer 1

This is the part that is wrong:
"loggers": {
"logger_name": {"handlers": ["azure", "console"]},
The "logger_name" needed to be populated with the App name so that
logger = logging.getLogger(__name__) worked properly.
Also a level is needed in the logger.
Here is what worked for me.
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'default': {
'format': '%(asctime)s - %(levelname)s - %(processName)s - %(name)s\n%(message)s',
},
},
'handlers': {
'azure': {
'class': 'opencensus.ext.azure.log_exporter.AzureLogHandler',
'formatter':'default'
# https://pypi.org/project/opencensus-ext-azure/
#Assumed ENV APPLICATIONINSIGHTS_CONNECTION_STRING
},
'console': {
'class': 'logging.StreamHandler',
'formatter': 'default',
},
},
'loggers': {
'polls': {
'handlers': ['azure', 'console'],
'level':'DEBUG'
},
}
}
The following options did not make a difference:
'level' parameter in handler
'filter':'[]' in handler
'stream':sys.stdout in handler.
I put the Appinsights connection string in an environmental variable, but the reference shows how to place in settings also. Also the original key in settings seems to work also.
APPLICATIONINSIGHTS_CONNECTION_STRING=InstrumentaionKey=<key uuid>
