We have an application stack where several different components hosted on different servers talk to each other.
The components are as below,
Apache Http Server - Web Server
IBM Websphere Portal - Web Application Server
Documentum Platform - Middleware Server
Oracle - Database Server
Below is a brief overview of how the system works.
User sends a http request to the web application
The web application receives the http request and sends a RPC call to the Middleware
Middleware receives the RPC call and sends a Database call to the Database
Middleware receives the response from the database
Webapplication receives the response from the middleware
Webapplication sends out an http resopne
FYI, RPC stands for Remote Procedure Call
Basically the entire flow would be something like HTTP request -> RPC call -> Database call/response -> RPC Response- > HTTP Response
All the 4 different components mentioned above are hosted on completely different servers.
As you can see, debugging becomes difficult and time consuming when an issue happens in one of these components.
Any suggestions you may have on how can we have a central logging/data flow system using graylog would be really helpful
