.SYNOPSIS
|
|
Vigilante (watchdog) de OmniRoute: garantiza que el servidor local este SIEMPRE arriba.
|
|
|
|
.DESCRIPTION
|
|
OmniRoute escucha en http://127.0.0.1:20128 y tarda ~60 s en quedar listo.
|
|
Este vigilante:
|
|
- Comprueba el puerto 20128 periodicamente.
|
|
- Si no hay proceso, arranca el servidor en segundo plano (oculto, desde un
|
|
directorio neutro para no contaminarse con .env de repositorios).
|
|
- Si hay proceso pero no responde tras el tiempo de arranque, lo mata y lo relanza.
|
|
Se lanza al iniciar sesion mediante la tarea programada "OmniRoute Watchdog".
|
|
|
|
.PARAMETER Once
|
|
Comprueba/arranca una sola vez, espera a que responda y sale (para pruebas).
|
|
.PARAMETER IntervalSeconds
|
|
Segundos entre comprobaciones del bucle de vigilancia (por defecto 120).
|
|
.PARAMETER StartupTimeoutSeconds
|
|
Segundos maximos de espera a que OmniRoute responda antes de considerarlo colgado.
|
|
.PARAMETER UseTray
|
|
Arranca OmniRoute con icono en la bandeja del sistema (por defecto NO, para maxima
|
|
fiabilidad en el arranque desatendido).
|
|
|
|
