Refer e20fd18a-ad8a-4775-b753-7b37bd5402dd_getHostInformation.log on the agent host for more details.

El registro de plug-in de host de agente indicado muestra lo siguiente:

<Date Time> acputil.py[671]:execute() Info:Running command: /sbin/ip link
<Date Time> host.py[1458]:getAliases() NICList :: ['vethxxxd@if256', 'lo', 'enxxx2', ............]
<Date Time> acputil.py[270]:getCommandTimeout() CommandTimeout value : 1800
<Date Time> acputil.py[665]:execute() commandTimeout value : 1800
<Date Time> acputil.py[671]:execute() Info:Running command: /sbin/ip addr show dev vethxxxd@if256
<Date Time> host.py[1465]:getAliases() Error:ip command not found

Si se ejecuta el comando manualmente, es el dispositivo que no existe el que se devuelve, a pesar de que el dispositivo existe.

[root@SourceHost logs]# /sbin/ip addr show dev vethxxxd@if256
Device "vethxxxd@if256" does not exist.

El comando de vínculo de IP de Red Hat devolvía varios dispositivos de red. La primera de estas no era válida y, como resultado, el siguiente comando provocó que el agente dejara de responder.

Comuníquese con el administrador de host para quitar el dispositivo de red no válido.
