Smarter Performance Insights for Your Cloud Servers
We’re excited to introduce a new section in the ServersCamp control panel – Performance Insights.
What is PSI and why it matters
Alongside traditional metrics like CPU, memory, disk I/O, and network throughput, you now get Pressure Stall Information (PSI) graphs. PSI is a Linux kernel feature that shows how much time processes inside your VM spend waiting on CPU, memory, or I/O.
Unlike simple “usage” charts, PSI highlights the real bottleneck of your workload:
- Is your VM waiting on CPU cycles?
- Does it lack memory and swap kicks in?
- Or is storage I/O too slow?
How to use it
With PSI, you can clearly see where the pressure comes from and take action:
- Add more vCPUs when CPU stall is high.
- Upgrade RAM allocation if memory stall persists.
- Consider faster storage or even a dedicated server when I/O stall is critical.
Together with the existing Performance Metrics (CPU, RAM, Disk, Network), these new insights give you a complete view of your server’s health and help you scale smarter.
