Response time indicates total time taken to process an incoming API request and send the response to the client during API transactions. This includes the time taken by API Gateway and the backend service to process the request. This widget provides a comprehensive overview of response time of all runtimes along with the details of the runtime with maximum and minimum latency to make informed business decisions. Click Top runtimes or All runtimes tab to view its respective response time in the runtime split and line graph.

You can customize the number of Top runtimes to display using Row settings under User preferences - Display. For more details, see Customizing Row Settings.

The Upward Trending tab displays the list of runtimes for which the response time trend percentage is lesser than the set response time trend threshold in the Runtime: Upward trending/improving section of the User preference - Threshold page. The Downward trending tab displays the list of runtimes for which the response time trend percentage is greater than the set response time trend threshold in the Runtime: Downward trending / deteriorating by section of the User preferences - Threshold page. For more details on how to set the trend threshold, see Change Threshold Settings.

Example:

Let’s determine the response time of the runtime A for 4 hours based on the following metrics. Let’s assume:

Response time of the runtime A for 4 hours=[((1.05∗10)+(2.07∗15)+(0.08∗20)+(1.07∗30)​)/75]=1.00ms

Similarly, let’s assume, the response time of the runtime B for 4 hours is 0.05ms

Let’s determine the response time of all runtimes for 4 hours. Let’s assume:

Response time of all runtimes=[((1.00∗75)+(0.05∗60)​)/135]=0.57ms

Response time trend analysis allows you to compare current and past response time based on the time range you choose to spot changes, which helps in making informed business decisions and predicting future performance..

You can replace 24 hours with the time range that you select. If the determined trend percentage of response time is

Example:

Let’s determine the response time trend percentage for all runtimes for 24 hours. Let’s assume:

Response time trend percentage for runtimes for 24 hours time range= [(0.57-3.41)/3.41] * 100 = -83.28%

The determined response time trend percentage, -83.28% (negative), appears in green with a downward arrow indicating that the error rate has decreased compared to the previous 24 hours.
