Providing additional stack trace information for time-based sampling in asynchronous execution environments

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• determining whether time-based sampling is activated to capture a time-based sampling data during execution of a JavaScript function, wherein the JavaScript function comprises an asynchronous function execute in a Node.js system;
• in response to determining that the time-based sampling is activated to capture the time-based sampling data, determining whether a callback stack trace is active;
• in response to determining that the callback stack trace is active, loading the callback stack trace;
• retrieving a current stack trace of the JavaScript function;
• and
• saving the loaded callback stack trace and the current stack trace of the JavaScript function as the time-based sampling data.

A computer-implemented system, comprising:

• a computer memory;
• and
• a hardware processor interoperably coupled with the computer memory and configured to perform operations comprising:
• determining whether time-based sampling is activated to capture a time-based sampling data during execution of a JavaScript function, wherein the JavaScript function comprises an asynchronous function execute in a Node.js system;
• in response to determining that the time-based sampling is activated to capture the time-based sampling data, determining whether a callback stack trace is active;
• in response to determining that the callback stack trace is active, loading the callback stack trace;
• retrieving a current stack trace of the JavaScript function;
• and
• saving the loaded callback stack trace and the current stack trace of the JavaScript function as the time-based sampling data.
