Keepalived SNMP가 작동하지 않습니다.

RHEL 7에서 Keepalived를 구성합니다. snmp를 통해서는 잘 작동합니다.

snmpwalk -v2c -cpublic 10.18.0.8 KEEPALIVED-MIB::vrrpInstanceTable

KEEPALIVED-MIB::vrrpInstanceTable = No more variables left in this MIB View (It is past the end of the MIB tree)

나는 Debian 10 Buster에서 같은 문제를 겪었고 마침내 여기에서 답을 찾았습니다.

분명히 기본적으로 snmpd는 다음 하위 트리에만 액세스하도록 구성되어 있습니다.

view   systemonly  included   .1.3.6.1.2.1.1
view   systemonly  included   .1.3.6.1.2.1.25.1
rocommunity public  default    -V systemonly

추가 등 뷰를 수정하여 다양한 방법으로 수정할 수 있습니다.

view systemonly included .1.3.6.1.4.1.9586

또는 다른 무제한 커뮤니티 등을 추가하세요.
