The API monitoring module displays the APIs in client, server, and local calls as well as the call traces in the upstream and downstream services, allowing you to check the key metrics like the number of requests, average response time, error rate, and throughput.

Prerequisites

Go to the API monitoring page in the APM console.

API overview

On the API monitoring page, select the target API on the left to display API analysis and Exception analysis on the right. You can select the target caller to view its details.

API analysis

API analysis allows you to select the target API service and view its total throughput, top 5 callers, average response time (99, 90, or 50 pct), error rate, and error code breakdown.
Metric
Description
Top 5 callers
The top 5 upstream applications/components calling the selected application API most frequently
Error code breakdown
The distribution trend of error codes returned by the current API
Note:
99 pct: Data in the 99th percentile in ascending order.
90 pct: Data in the 90th percentile in ascending order.
50 pct: Data in the 50th percentile in ascending order.

Exception statistics

Besides basic metrics, you can also view top 5 APIs in the current application in terms of average response time and error rate, which are intelligently filtered by the exception analysis module. You can click View details above the curve to view the call trace of the target API in the last 15 minutes, so you can drill down to the issue to troubleshoot it quickly.

Upstream and downstream analysis

You can switch between the Upstream analysis and Downstream analysis tabs to analyze upstream and downstream calls and quickly identify performance bottlenecks.
