Responses times gateway endpoints

Products

• CA API Gateway

Issue/Introduction

Looking for a quick way to gather response times of various endpoints after some performance tests were completed. 

Does Broadcom recommend any other solution? 

Environment

Gateway 10.X 11.X

Resolution

The dashboard a good starting point to review end-points and response times 

Response times for each endpoint can be logged in SSG_DB or the audit DB using the Audit Detail Assertions

Link how to track latency 

https://techdocs.broadcom.com/us/en/ca-enterprise-software/layer7-api-management/api-gateway/10-1/policy-assertions/assertion-latency.html

Summary:

Context variables related to track time taken:

assertion.latency.ms - placed after any assertions to see how long it took

request.elapsedTime  - place at the end of a service or in a Global message complete policy equals total time service took 

service.resolutionUri - context variable to log the resolved URI 

service.name - context variable to log service name 

httpRouting.latency - context variable to log latency fo the router assertions 

Another good method when performance is isolated is to audit log before and after assertions 

Audit Detail assertion:

Policy#: ${assertion.numberstr}; assertion.latency=${assertion.latency.ms}; elapsedTime=${request.elapsedTime}; Policyname ${policy.name}; ServiceName ${service.name}; Service URl  ${service.resolutionUri}

ASSERTIONS under question

Audit Detail assertion:  

Policy#: ${assertion.numberstr};  assertion.lat=${assertion.latency.ms}; ElapsedTime=${request.elapsedTime}; GatewayTime: ${request.time}
