| client | xpra.client.subsystem.ping |
| client connection | xpra.server.source.ping |
| server | xpra.server.subsystem.ping |
Both packet types may flow in either direction.
| Packet Type | Arguments |
|---|---|
ping |
monotonic timestamp in milliseconds, optional source ID |
ping-echo |
echoed timestamp, 1/5/15-minute loads scaled by 1000, latency in milliseconds, optional source ID |
The timestamp correlates the response with the request; it is not wall-clock time. A negative latency means that no latency measurement is available.
