How to evaluate the complete processing time taken by an Apigee proxy

[akashtp]

The current metrics I am aware of are:

requestProcessingTime = context.getVariable("target.sent.end.timestamp") - context.getVariable("client.received.start.timestamp")

Looks like this doesn't show the time Apigee took to process a request and lapsed time in sending the response. Is my understanding correct?

@Akash Prabhashankar,

Im not sure why are you using target.sent.end.timestamp. Wont client.sent.end.timestamp would be a better metric to give the exact time?

See this question in the community: https://community.apigee.com/questions/3756/elapsed-time-to-be-sent-as-a-part-of-response-from.html

Here is the link to Apigee Community article describing how to get data that we require : https://community.apigee.com/questions/3756/elapsed-time-to-be-sent-as-a-part-of-response-from.html . So you basically we may want to use : client.sent.end.timestamp - client.received.start.timestamp instead of target.sent.end.timestamp -

client.received.start.timestamp .
