Telemetry Widget
The Telemetry widget shows how hard the machine running Lastboard is working right now. It is listed as Server Health in the widget picker.
Description
Section titled “Description”Up to three ring gauges — CPU, RAM and temperature — for the server Lastboard itself is installed on. No agent, no exporter and no configuration: the readings come from the server you are already running.
Metrics Displayed
Section titled “Metrics Displayed”| Metric | Meaning |
|---|---|
| CPU | Processor use, as a percentage. |
| RAM | Memory in use, as a percentage of the total. |
| TEMP | The server’s temperature reading. |
Each ring is green while the value is comfortable, amber as it climbs and red when it is high: above 60% and 80% for CPU and RAM, above 50 °C and 70 °C for temperature. Those two temperatures are the thresholds whichever unit you display.
Configuration Options
Section titled “Configuration Options”| Option | Default | Description |
|---|---|---|
| Metrics | All three | Which of CPU, RAM and TEMP the widget draws. At least one has to stay on — the last one you try to switch off comes back. |
| Refresh Rate | 5s | How often the widget redraws: 1s, 2s, 5s or 10s. |
The Personalize tab adds a border color and a border width (Thin, Regular or Thick) for the widget’s card.
Saving the metrics resizes the widget. One metric takes one cell, two take two, three take three — so the gauges keep their proportions instead of stretching. The widget has no resize handle of its own in Edit Mode; this is how its width is set.
- The server measures once a second and pushes the readings to every open Lastboard tab. It skips the measurement entirely when nobody has Lastboard open. The Refresh Rate setting decides how often the widget redraws with what arrives.
- Nothing is recorded. This widget is the present moment only — for a history of your services over time, see Monitoring & Uptime.
- Readings are read from the Linux kernel. On a server that is not running Linux there is nothing to read: CPU and RAM sit at 0%.
- Temperature needs a thermal sensor the server can read. Where there is none — which includes many virtual machines — the gauge shows -1 instead of a reading.
- The temperature unit follows Measurement Units in your preferences: °C or °F.
