Performance Measurement with Sentry

from Sentry Memo Performance Measurement with Sentry

• Included Instrumentation for React | Sentry Documentation
  • Performance measurement is now available. ts

export const getNewTalkID = () => {
  const transaction = Sentry.startTransaction({ name: "getNewTalkID" });
  const span = transaction.startChild({ op: "getNewTalkID" });
 
  fetch(...)...
    .then((text) => {
    	  ...
          span.finish();
          transaction.finish();
        });
    })
    .catch(() => {
      Sentry.captureMessage("ERROR_ON_SERVER: getNewTalkID");
      ...
    });
};

If the filter is set to p100, outliers are included in the order of slowest to fastest. In this example, there’s one outlier that took 16 seconds. Actually, this is what I wanted to know (the time it takes for the server to sleep and wake up after receiving a request).
