SimTX Guide/Health
The Health tab shows the load and state of the server you are connected to.
The header
The header shows the server's name, when the report was last updated, and a status: Healthy, Attention or Degraded. Auto-refresh updates the report every 5 seconds; Refresh updates it now.
Problems show as warnings below the header:
- The server is not accepting new connections.
- System CPU at a percentage of 90 or more.
- Server memory is nearly full.
Overview
| Figure | Meaning |
|---|---|
| Uptime | How long the server has been running. |
| Clients | Connected programs, with the number of stations in use. |
| Transmitters | Transmissions on the air. |
| Receiver groups | Groups of receivers that share processing. |
| Sim time | The simulation clock, in UTC. |
Resources and work queues
Resources shows the server's CPU, the machine's CPU, memory, threads, open files and load average. Work queues shows how many session tasks, receiver DSP jobs and propagation jobs are running and waiting. Waiting jobs, overruns and Stalls above zero mean the server is falling behind.
Transmitters and receivers
| Table | Columns |
|---|---|
| Transmitters | Callsign, Frequency, Mode, Rate, Buffer (audio waiting at the server), Last data and Connected. |
| Receivers | Callsign, Center, Rate, Queue, Dropped, Group and Connected. |
A short Buffer or a Last data time of a second or more means that transmitter's audio is not arriving fast enough. A full Queue or rising Dropped count means that receiver isn't reading its samples fast enough.
