I made my fastapi app to log data into json format
also I added
span_idtrace_idintimport json_logging
import logging
import sys
from config import config
from fastapi import FastAPI
app = FastAPI(title=config.app_title)
class JSONLogWebFormatter(json_logging.JSONLogFormatter):
"""
Formatter for web application log
"""
def _format_log_object(self, record, request_util):
json_log_object = super(JSONLogWebFormatter, self)._format_log_object(
record, request_util
)
current_span = trace.get_current_span()
if current_span:
json_log_object["span_id"] = current_span.get_span_context().span_id
json_log_object["trace_id"] = current_span.get_span_context().trace_id
json_log_object.update(
{
"correlation_id": request_util.get_correlation_id(
within_formatter=True
),
}
)
return json_log_object
json_logging.init_fastapi(enable_json=True, custom_formatter=JSONLogWebFormatter)
json_logging.init_request_instrument(app, custom_formatter=JSONLogWebFormatter)
# init the logger as usual
logger = logging.getLogger()
logger.setLevel(logging._nameToLevel[config.log_level.upper()])
logger.addHandler(logging.StreamHandler(sys.stdout))n

03/01/2023, 3:03 PMYou will have to use the SDK https://github.com/open-telemetry/opentelemetry-python/tree/main/docs/examples/logs
Or If your application is running in docker or k8s, then logs emitted to stdout will be collected by signoz

03/01/2023, 3:05 PMI'm in k8s and other logs are collecting except this app
I think something are wrong with my log structure
Or with my configuration
@nitya-signoz What can I do to fix that?

03/01/2023, 3:14 PMIf you logs are getting printed to stdout then it will be collected, did you try to filter in the UI

}here is the sample log
@nitya-signoz
I have removed trace_id and span_id from logs but I'm not able to see logs in signoz

03/05/2023, 3:42 PMCan you check if by any change if the namespace where you have deployed the above application is excluded in the otel collector config file receiver ?

03/05/2023, 8:55 PM- type: filter
id: remove_some_logs
expr: 'resource["k8s.namespace.name"] matches "(^stage-.*$)" and resource["k8s.namespace.name"] != "stage-this-project"'
drop_ratio: 1.0stage-this-project is the name of the namespace
I think this filter is not making problems
n
nitya-signoz
03/06/2023, 5:18 AMIt shouldn’t cause any issue, but try removing it?
or if there is something else.
m
Muhammed Hussein Karimi
03/06/2023, 5:22 AMI will check
But there are no other drop filters
If I remove that my storage will become 100% full

03/06/2023, 5:22 AMGot it then try deploying in some other namesapce ?
m
Muhammed Hussein Karimi
03/06/2023, 6:58 AMI will test that
I changed the namespace but problem persist
