Dear Ravi Gadhia,

Thanks for your reply..

we are trying to monitor how the ERP Application works, we are using the tool DataDog / Elastic APM [Application monitoring tools], With a proper application monitoring tool we could see how the components of the Application works ( like Interaction of Application with DB, and filestorage, also how the SQL query works )

To make the oddo work with the DataDog we need to do some changes in the odoo to talk to the datadog. They have given the instruction at the url

datadog:

https://docs.datadoghq.com/tracing/advanced/manual_instrumentation/?tab=python

Elastic APM:

https://www.elastic.co/blog/creating-custom-framework-integrations-with-the-elastic-apm-python-agent

So i want a middleware to integrate odoo with any on of these applications..

it seems datadog monkey patching lib and you have to runt odoo as script with datadog

ref: http://pypi.datadoghq.com/trace/docs/web_integrations.html#flask

so import ddtrace as soon as possible and start odoo with WSGI app

app is https://github.com/odoo/odoo/blob/8f4b98e67fe49516c0c830524de351db67c58357/odoo/service/wsgi_server.py#L102

For elastic you have to override request dispatcher with elasitc client
