Introduction to Server Monitor

The Server Monitor is a feature in erty that lets you track your server’s health in real time.

With this tool, you can monitor:

  • CPU usage – how much processing power is being used
  • RAM usage – how much memory is in use
  • Disk usage – how much storage space is being used

Its goal is to notify you immediately when a resource exceeds the usage threshold you set, allowing you to act before the server slows down or crashes.

 

Which types of servers can I monitor

The Server Monitor works on servers where you can install and run scripts from the terminal.

Here are some examples:

âś… Compatible

  • Dedicated Servers
  • VPS (Virtual Private Servers)
  • Cloud servers (AWS EC2, Google Cloud, Azure, etc.)
  • Self-hosted environments with root or SSH access

⚠️ To verify

  • Shared Hosting servers
  • Other managed environments that might have security restrictions

Note: In shared hosting and managed environments, settings and possible blocks for installing third-party scripts depend on the provider. Before proceeding, check with your hosting provider whether running external scripts is allowed.

Check interval

  • How often erty collects data from your server.
  • The shorter the interval, the more up-to-date your data will be (1 min, 5 min, 10 min...).
  • Important: If you change this value after creation, you must reinstall the script.

Advanced settings
Optional configuration panel for more control.

  • Custom timeout – how long to wait for a server response before marking it as unreachable.
  • Direct project assignment.

Alerts

  • Create rules to be notified when a resource exceeds a limit.
  • Metric – choose CPU usage, RAM usage, or Disk usage.
  • Rule – condition (e.g., is higher than).
  • Value – the threshold in percentage (e.g., 90).

Pro Tips

đź’ˇ Useful suggestions:

  • Set alert thresholds slightly below the critical limit (e.g., RAM 80% instead of 95%) to give yourself time to react.
  • If managing multiple servers, use Projects to group them and filter easily.
  • Regularly check resource usage graphs to spot recurring issues or unusual spikes.
  • Always configure at least two notification channels so you don’t miss important alerts.
