# Configuring a Monitoring node for Scaling and High Availability[](#configuring-a-monitoring-node-for-scaling-and-high-availability "Permalink")

在 GitLab 12.0 中[引入](https://gitlab.com/gitlab-org/omnibus-gitlab/-/issues/3786) .

您可以配置 Prometheus 节点以监视 GitLab.

## Standalone Monitoring node using Omnibus GitLab[](#standalone-monitoring-node-using-omnibus-gitlab "Permalink")

Omnibus GitLab 软件包可用于配置运行[Prometheus](../monitoring/prometheus/index.html)和[Grafana](../monitoring/performance/grafana_configuration.html)的独立 Monitoring 节点. 监视节点不是高度可用. 请参阅[缩放和高可用性](../reference_architectures/index.html)的 GitLab 扩展和高可用性选项的概述.

以下步骤是使用 Omnibus 配置运行 Prometheus 和 Grafana 的 Monitoring 节点的最低必需步骤：

1.  SSH 进入"监视"节点.
2.  从 GitLab 下载页面使用**步骤 1 和 2** [下载/安装](https://about.gitlab.com/install/)所需的 Omnibus GitLab 软件包.
    *   不要完成下载页面上的任何其他步骤.
3.  [`CONSUL_SERVER_NODES`](../postgresql/replication_and_failover.html#consul-information) ，请确保收集[`CONSUL_SERVER_NODES`](../postgresql/replication_and_failover.html#consul-information) ，它们是 Consul 服务器节点的 IP 地址或 DNS 记录. 请注意，它们显示为`YYYY consul1.gitlab.example.com ZZZZ`

4.  编辑`/etc/gitlab/gitlab.rb`并添加内容：

    ```
    external_url 'http://gitlab.example.com'

    # Enable Prometheus
    prometheus['enable'] = true
    prometheus['listen_address'] = '0.0.0.0:9090'
    prometheus['monitor_kubernetes'] = false

    # Enable Login form
    grafana['disable_login_form'] = false

    # Enable Grafana
    grafana['enable'] = true
    grafana['admin_password'] = 'toomanysecrets'

    # Enable service discovery for Prometheus
    consul['enable'] = true
    consul['monitoring_service_discovery'] =  true

    # Replace placeholders
    # Y.Y.Y.Y consul1.gitlab.example.com Z.Z.Z.Z
    # with the addresses of the Consul server nodes
    consul['configuration'] = {
       retry_join: %w(Y.Y.Y.Y consul1.gitlab.example.com Z.Z.Z.Z),
    }

    # Disable all other services
    gitlab_rails['auto_migrate'] = false
    alertmanager['enable'] = false
    gitaly['enable'] = false
    gitlab_exporter['enable'] = false
    gitlab_workhorse['enable'] = false
    nginx['enable'] = true
    postgres_exporter['enable'] = false
    postgresql['enable'] = false
    redis['enable'] = false
    redis_exporter['enable'] = false
    sidekiq['enable'] = false
    puma['enable'] = false
    node_exporter['enable'] = false
    gitlab_exporter['enable'] = false 
    ```

5.  运行`sudo gitlab-ctl reconfigure`来编译配置.

下一步是告诉所有其他节点监视节点在哪里：

1.  编辑`/etc/gitlab/gitlab.rb` ，然后添加或查找并取消注释以下行：

    ```
    gitlab_rails['prometheus_address'] = '10.0.0.1:9090' 
    ```

    其中`10.0.0.1:9090`是 Prometheus 节点的 IP 地址和端口.

2.  保存文件并[重新配置 GitLab，](../restart_gitlab.html#omnibus-gitlab-reconfigure)以使更改生效.

## Migrating to Service Discovery[](#migrating-to-service-discovery "Permalink")

使用`consul['monitoring_service_discovery'] = true`启用使用服务发现进行`consul['monitoring_service_discovery'] = true` ，请确保未在`/etc/gitlab/gitlab.rb`设置`prometheus['scrape_configs']` . 在`/etc/gitlab/gitlab.rb`同时设置`consul['monitoring_service_discovery'] = true`和`prometheus['scrape_configs']`都会导致错误.
