표시된 에이전트 호스트 플러그인 로그에는 다음이 표시됩니다.

<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> host.py[1465]:getAliases() Error:ip command not found

 

수동으로 명령을 실행하면 디바이스가 존재하더라도 반환되지 않는 디바이스입니다.

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

 

Cause

Red Hat IP 링크 명령이 여러 네트워크 디바이스를 반환하고 있었습니다. 이 중 첫 번째가 유효하지 않아 다음 명령으로 인해 에이전트가 응답을 중지했습니다.

 

Resolution

호스트 관리자에게 연결하여 잘못된 네트워크 디바이스를 제거합니다.
