<Date Time> INFO [Thread-78 (ActiveMQ-client-global-threads)] [com.emc.archway.service.eventservice.EventServiceBean] [AppSync Server] [] 123->>> EVENT [GENL_000055]: An error occurred while running getHostInformation on host SourceHost. Refer e20fd18a-ad8a-4775-b753-7b37bd5402dd_getHostInformation.log on the agent host for more details.

Il log del plug-in host dell'agent indicato mostra:

<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

Se si esegue il comando manualmente, è il dispositivo che non esiste e viene restituito, anche se il dispositivo esiste.

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

Il comando link IP di Red Hat restituisce diversi dispositivi di rete. Il primo di questi non era valido e, di conseguenza, il comando successivo ha fatto sì che l'agent smettesse di rispondere.

Contattare l'host administrator per rimuovere il dispositivo di rete non valido.
