Monitoring

Overview 

 

 The lab uses a self-hosted monitoring stack to track CPU, GPU, memory, disk, network, and per-process resource usage across all lab servers. Metrics are visualised in Grafana, which is available at https://grafana.lab.pyarelal.xyz . Log in with your lab account via the Sign in with Kanidm button. 

 What is monitored 

 

 CPU usage (by type: user, system, iowait, etc.) 

 RAM usage (used, cached, buffers) 

 Network traffic (sent and received)

 Using the dashboard 

 After logging in, open the Infrastructure Overview dashboard. Use the Host dropdown at the top to switch between servers. The time range selector in the top right controls how far back the graphs show. 

 The dashboard is divided into three sections: 

 

 System — CPU, RAM, network, and disk panels visible for all hosts 

 GPU — GPU panels, populated only for GPU-equipped hosts 

 Processes — top 10 processes by CPU and memory usage
