Introduction to NodeJS monitoring with Prometheus

Let's take a look at how to monitor and instrument your NodeJS code using Prometheus. Very simple and effective way to find out how long your functions take and how many requests or operations your code is performing per second :)

These videos are just SOOO useful. Where everything is filled with, at this point, useless basic content, you actually provide real life information. Thank you sooo much man!

Like your style of teching things with cool music in the background :)

Finally a good video on using Prometheus. Great work dude.

Helped me a TON as compared to prom-client's own documentation. Thanks!

Fantastic tutorial NodeJS monitoring with Prometheus.

Great video sir, Will recommend to my friends

Marcel - your video guide is very good - many thanks

[teste-yhdf]

very underrated! Im new to this and its becommin much clear!

[azidahaka]

Great, very informative video! Just getting started with Prometheus and Node.js here and this helped a ton. Just a tip - I found the background music kind of distracting/too loud, but otherwise great content. I was also wondering if you could do a video on your arm routine? Thanks!

Nenhum tutorial em português tava ensinando tão bem, tive que vir aqui aprender, muito obrigado <3

[tusharrastogi]

Really informative...would be great help for us, if you also create a video for nodejs with cluster and pm2 cluster as well.

Thanks for this awesome video. I was looking forward for the same. But I have a doubt that I am running the backend with node js and I need the login count in graffana with each time the user login, but once the user logged out then how it will manage the same. Looking forward for your response.

Hello thank you your tutorials are great
can you do a tutorial on exporting stackdriver to monitor a cloud server (google cloud)

[banjovictor]

Hi Marcel.
Thank you for sharing this but can this set up equally work with restify middleware?

[РусланИсаев]

oooohh man! thank u for this explanations!

[luisbraga]

Keep up with the awesome content !
Always relevant and pertinent content with very realistic use cases !
Thank you !

How can I apply the same in Prometheus operator.

Thanks for video, Is it possible to monitor mqtt traffic, or websockets?

Is it possible to monitor whole node.js work? Event-loop status/charge, memory, cpu charge by node.js?

If we can only observe charge of http requests (and for requests we need to connect some library code at all code paths manually - maybe it can be solved by some middleware? ) what is the sense?

[wolfdhib]

hello, thank for sharing but if I have many other requests paths in the NodesJS app, So in order to monitor on the every request path, Should I manually edit every function that serves a request?

[sriyulianti]

Hi, thanks for the video. It is really helpful. However I have a problem when I adopt your approach to my own node.js server and used your code for docker-compose, prometheus and grafana but I got this error when I launch prometheus targets from browser even though my web server is already UP :
"INVALID" is not a valid start token
Do you have any idea why?
