Every server you connect or buy reports its resource usage to Symplax through the agent. There is nothing to configure.

​
What is measured

The agent reports these figures, as percentages of the server’s total:
  • CPU usage
  • Memory usage
  • Disk usage
It also reports network traffic in and out, per-container Docker stats, and the server’s operating system, CPU cores, memory and disk size, which appear on the server page.

​
Where to see it

Dashboard

Resource Usage Over Time charts CPU across your servers, with 1H, 24H and 7D views. The Uptime card shows the share of your servers that are online right now.

Servers page

Avg CPU, Avg RAM and Avg Disk across all servers, plus each server’s own CPU, RAM and disk usage on its card.

Server page

The Overview tab shows CPU, memory and disk for that server, its connection details, and Last Seen, the last time the agent checked in.

Maintenance

The server’s Maintenance tab shows root disk usage, reclaimable Docker space and build cache. Cleanup removes build cache, dangling images and stopped containers, never running apps or volumes.
The dashboard updates live while you have it open.

​
History

Symplax saves a data point for each server at most every 10 seconds. There is no long-term history beyond that. If you need months of data, run your own monitoring stack on the server.

​
Online and offline

A server counts as online while its agent keeps reporting. If Symplax hears nothing for about 90 seconds, it marks the server offline. Symplax doesn’t ping your server from outside. Offline means the agent stopped reporting, which can be because the machine is down, the agent stopped, or the server lost its outbound internet connection.
This is about the server itself. To check that your app’s public URL responds, see uptime monitoring.

​
Alerts

These alerts exist today: Offline and online alerts always appear as dashboard notifications, and are also emailed. Memory alerts are email only. Docker cleanup alerts arrive as an email and a notification. Every email here, and the cleanup notification, follows your Server Alerts setting below.
No offline alert is sent for a bought server paused because your wallet ran out. You get the pause notice instead.

​
Turn email alerts on or off

Go to Settings, find Notification Preferences, and switch Server Alerts. It is on by default.
There are no alerts for high CPU or a filling disk yet. Check the dashboard, or watch disk usage on the server page, especially on servers with many images or large databases.
