Hi Everyone 

Need som help here, has anyone worked on or implemented this before - integrating webMethods with Datadog for end-to-end monitoring? Any guidance or reference links would be appreciated.

I have integrated with Datadog for trace, metrics and log integration at a few customers. But I have accomplished this using OpenTelemetry and Otelscope. Otelscope is a third party webMethods plugin for OpenTelemetry integration. See https://www.nibl.tech/products/otelscope

I Have worked on splunk integrated with webmethods, I guess there must be an option in data dog to connect a database or configure a file directory.

with connect to a database - you can connect mws or IS database 

with file directory option: you can connect server log directory.

After this you need to create couple search patterns with key words used in your error logging. that will give you results to generate reports or alert emails.

Hello @Yogeshwar Kabra,

you have an very interesting question, but shared a bit too few details for an detailed answer.
The webMethods Suite has many various products from API GW over Integration to B2B and MFT as well as BPMN in onPrem world.
When you say "end2end monitoring" what products are involved and are you talking about onPrem or SaaS?

When we assume, as example, that you are using the IBM webMethods Hybrid Integration,
then you have in the integration space options like "Dual Channel" support to feed your external system easily with tracking data.

This works for onPrem (self hosted) as well as in Develop Anywhere, Deploy Anywhere (DADA) world.
For more details see also:
https://www.ibm.com/docs/en/wm-end-to-end-monitoring?topic=shtm-self-hosted-agent-configuration-share-data-external-systems
What you will see there is that DataDog is planned to be suppported, but not covered today.

For any other case there remains the option of an "Custom Implementation"
