DEC Monitoring

Welcome to the monitoring setup for DEC! This guide explains how to access the Grafana dashboards we’ve set up to monitor CPU, memory, and node availability across the cluster.

This monitoring system is a prototype and will be improved over time. If you have any feedback or suggestions, please let us know! It is not yet exposed to the public internet, so you need to access it via SSH port forwarding.

Accessing Grafana via SSH Port Forwarding

Since port 3000 is not exposed publicly, you need to forward it from your local machine:

Command (from your laptop):

ssh -L 3000:localhost:3000 mardec.in2p3.fr
  • Leave this terminal window open during your session
  • Then open your browser and visit:
http://localhost:3000

You will be connected to the internal Grafana service running on mardec.

Login Credentials

Use the following login:

Username: decuser
Password: (sent to you by email)

If you’ve lost the password, just ask the admin (nicely 😄).

Available Dashboards

Once logged in, you'll see:

  • All Nodes: CPU & Memory Usage
    → Live CPU & memory usage for all nodes in a single panel http://localhost:3000/goto/T3oMR9TNR?orgId=1

  • DEC Disk Usage Overview
    → Disk usage across all DEC disks http://localhost:3000/goto/5IjxRrTHg?orgId=1
