1. 개요

1.1. 문서 목적

본 문서(설치가이드)는, IaaS(Infrastructure as a Service) 중 하나인 Openstack 기반의 Cloud 서비스 상태 및 자원 정보, 그리고 VM Instance의 시스템 정보를 수집 및 관리하고, 사전에 정의한 Alarm 규칙에 따라 실시간으로 모니터링하여 관리자에게 관련 정보를 제공하기 위한 서버를 설치하는데 그 목적이 있다.

1.2. 범위

본 문서의 범위는 Openstack 모니터링을 위한 오픈소스인 Monasca 제품군의 설치 및 관련 S/W(Kafka, Zookeeper, InfluxDB, MariaDB) 설치하기 위한 내용으로 한정되어 있다.

1.3. 참고자료

7. Reference : Cross-Project(Tenant) 사용자 추가 및 권한 부여

Openstack 기반으로 생성된 모든 Project(Tenant)의 정보를 하나의 계정으로 수집 및 조회하기 위해서는 Cross-Tenant 사용자를 생성하여, 각각의 Project(Tenant)마다 조회할 수 있도록 멤버로 등록한다. Openstack Cli를 이용하여 Cross-Tenant 사용자를 생성한 후, Openstack Horizon 화면으로 통해 각각의 프로젝트 사용자 정보에 생성한 Cross-Tenant 사용자 및 권한을 부여한다. 1. Cross-Tenant 사용자 생성

    $ openstack user create --domain default --password-prompt monasca-agent
    $ openstack role create monitoring-delegate

  1. Project 사용자 추가

    각각의 프로젝트 멤버관리에 추가한 Cross-Tenant 사용자 정보를 등록한다.

    추가한 Cross-Tenant 사용자를 선택 후, 생성한 Role을 지정한다.
