oVirt从4.4开始集成了Grafana作为监控门户，但使用oVirt Node+HostedEngine方式部署的环境默认是未开启的，如果想使用的话，可以在部署完成后通过engine-setup重新开启Grafana，以下为具体步骤：
1、首先在Node主机上将HostedEngine设置为全局维护模式，执行以下命令：
hosted-engine –set-maintenance –mode=global
2、在HostedEngine里重新setup，执行以下命令：
engine-setup –reconfigure-optional-components
注意Grafana的配置项选择默认的Yes：Configure Grafana on this host (Yes, No) [Yes]:
注意有配置Grafana用户密码的地方，具体过程如下：
[root@engine100 ~]# engine-setup –reconfigure-optional-components

Setup can automatically configure the firewall on this system.
Note: automatic configuration of the firewall may overwrite current settings.
Do you want Setup to configure the firewall? (Yes, No) [Yes]:
[ INFO ] firewalld will be configured as firewall manager.
–== DATABASE CONFIGURATION ==–
DWH database is on localhost, user for Grafana not configured yet.
Create a local user for Grafana? (Yes, No) [Yes]:
The detected DWH database size is 29.32115077972412 MB.
Setup can backup the existing database. The time and space required for the database backup depend on its size. This process takes time, and in some cases (for instance, when the size is few GBs) may take several hours to complete.
If you choose to not back up the database, and Setup later fails for some reason, it will not be able to restore the database and all DWH data will be lost.
Would you like to backup the existing database before upgrading it? (Yes, No) [Yes]:
Perform full vacuum on the oVirt engine history
database ovirt_engine_history@localhost?
This operation may take a while depending on this setup health and the
configuration of the db vacuum process.
See https://www.postgresql.org/docs/12/sql-vacuum.html
(Yes, No) [No]:
–== OVIRT ENGINE CONFIGURATION ==–
Perform full vacuum on the engine database engine@localhost?
This operation may take a while depending on this setup health and the
configuration of the db vacuum process.

Grafana admin password:
Please confirm password:
[WARNING] Password is weak: The password fails the dictionary check – it is based on a dictionary word

3、第二步的setup执行完成后，到主机上将HostedEngine的维护模式置回none，执行如下命令：
hosted-engine –set-maintenance –mode=none
4、重新访问engine管理台，可以看到有了“监控门户”，使用第二步中setup过程中配置的用户密码即可访问：
