Monitor NodeJs

[Yasmine Mbarek]

Hello everyone , 

Is there any other way to monitor NodeJS application without touching anything in the app.js file ?

Thank you.

Depends what sort of monitoring you want to do.  You can:

- Test it using blackbox_exporter.  This will tell you if the app is up or down, and the latency in responding to test requests.

- Read its logfiles using mtail or grok_exporter.  This will let you synthesize metrics like number and type of requests and number of failures, as long as such things are logged.
