How to Check if NodeJs IO loop is doing too much heavy task or not on Google App Engine?

[Sudhanshu Gaur]

I am running my NodeJs app on Google App Engine and as NodeJs IO loop runs in a single-threaded environment that's why i wanted to ask is there any way to check if my IO loop is doing heavy tasks or not ??

You can use the Stackdriver Profiler tool to gain insights into the different processes under the main event loop that are consuming the most runtime resources. You can also simply profile the event loop yourself and log the results to Stackdriver Logging.
