OSB: how to figure out the execution time of OSB proxy

Question

Trying to figure out how to determine the execution time taken for any given OSB proxy. Seems like the OSB built-in alerting facilities can display the average response time of all calls to a proxy but not individually. Is there a way to dig this out from the monitoring data being collected?

Answer 1

Service monitoring which comes OOTB is supposed to be aggregated because in usual scenarios you dont need to see the processing time of a specific request. From a performance monitoring perspective the useful data usually is average processing time and minimum or maximum processing time for any request within the aggregation interval which is provided by OSB OOTB.
Now, in some cases the business might want to track each request individually. So, for example they can track how long did it take to process a specific order. OSB does not provide this feature OOTB. There are multiple ways to get this implemented. Two of the most common ways are:
1. Add a start and end time capturing in Proxy Services. You can use logging/reporting/publish to a DB etc to achieve this. But this is indeed intrusive and you will need to do this for every Proxy which needs to be monitored at every instance level. This is also a slight overhead in processing in itself.
2. Use monitoring products which can monitor the WS invocations externally. This will mean more investment but definitely a much better solution. You can consider using different products from Oracle and other vendors based on your requirements, features of products and costs. A few examples are OWSM, Oracle EM, CA Wily etc.
