Red Hat Summit7.3. Alertmanager Webhook 추가
기존 Alertmanager 구성에 새 Webhook를 추가하여 스토리지 클러스터 상태에 대한 실시간 경고를 수신할 수 있습니다. 들어오는 웹 후크를 활성화하여 타사 애플리케이션에 비동기 메시지를 허용해야 합니다.
예를 들어 Red Hat Ceph Storage 클러스터에서 OSD가 다운된 경우 Google 채팅에서 알림을 전송하도록 Alertmanager를 구성할 수 있습니다.
사전 요구 사항
- 모니터링 스택 구성 요소가 활성화된 Red Hat Ceph Storage 클러스터.
- 수신 타사 애플리케이션에 구성된 들어오는 Webhook입니다.
절차
cephadm쉘에 로그인합니다.예제
cephadm shell
[root@host01 ~]# cephadm shellCopy to Clipboard Copied! 알림에 Webhook를 사용하도록 Alertmanager를 구성합니다.
