uptime command in webapp shows [0,0,0]

Asked by abdullah527382

Lookng at tutorial: How To Monitor CPU Use on DigitalOcean Droplets | DigitalOcean I’m trying to get CPU usage / load metrics of the environment where my node application is running but running the command uptime just gives load average as load average: 0.0, 0.0, 0.0 whereas in both my local dev (WSL) and docker container has the proper load avg which I’m later using in my node app with func: os.loadavg(). I assume there are permission errors but isn’t there any way to get system load info i.e. cpu, mem, etc. in a web app env or will I need to recreate as a droplet? In the tutorial they also run uptime with no issues. Thanks

Heya,

You are correct, it’s permissions issues as you are not on a dedicated environment. As you know, App Platform is a Platform-as-a-Service (PaaS) offering that allows developers to publish code directly to DigitalOcean servers and as such you do not have the proper permissions to show you the load averages.

Additionally, I don’t think there is a way to check the load on the servers.

Hi there,

It’s great to see you leveraging DigitalOcean’s resources to monitor your application’s performance.

Regarding the issue you’re encountering with the uptime command on the App Platform, it’s important to understand that the DigitalOcean App Platform operates differently from a traditional Droplet or a local development environment like WSL. In the App Platform, your application is running in a more abstracted environment, where certain system-level metrics and commands might not function as they would on a dedicated virtual machine or your local setup.

Regarding your specific issue with the uptime command showing [0,0,0], this is likely due to the abstracted nature of the App Platform. The platform is designed to abstract away many of the underlying infrastructure details, including certain aspects of system load monitoring.

Instead of relying on traditional Linux commands like uptime, I recommend utilizing the built-in monitoring tools provided by the App Platform. These tools are specifically designed to give you insights into your application’s performance, including CPU and memory usage, in a way that’s tailored to the platform’s unique environment.

Now, if you were working on a traditional Droplet, the output of uptime showing load averages like 0.0, 0.0, 0.0 would generally indicate a system that’s not under much load. This could be completely normal, especially for a server that’s not handling heavy traffic or processing.

To get a more interactive and detailed view of your system’s performance on a droplet, I would suggest using a tool like htop. This command-line tool provides a dynamic real-time view of your server’s resource usage, including CPU, memory, and process management. It’s a powerful tool for diagnosing performance issues and understanding how your server is handling its workload.

In summary, for your App Platform scenario, lean on the platform’s monitoring features for insights. If you ever transition to or work with a droplet, tools like uptime and htop are invaluable for understanding system performance.

Hope this helps and happy coding!

Best,

Bobby
