I have disable the embeded GitLab Prometheus in my docker-compose file and setup exporter as mentionned in this documentation (https://docs.gitlab.com/ee/administration/monitoring/prometheus/#using-an-external-prometheus-server) like this : ```yaml version: '3' services: web: image: 'gitlab/gitlab-ce:latest' restart: always hostname: 'mycustomurl' environment: TZ: Europe/Paris GITLAB_OMNIBUS_CONFIG: | external_url 'https://mycustomurl' gitlab_rails['monitoring_whitelist'] = ['127.0.0.1', 'PROMETHEUS_IP'] prometheus['listen_address'] = '0.0.0.0:9090' prometheus['enable'] = false gitlab_monitor['listen_address'] = '0.0.0.0' gitlab_monitor['listen_port'] = '9168' gitaly['prometheus_listen_addr'] = "0.0.0.0:9236" node_exporter['listen_address'] = '0.0.0.0:9100' redis_exporter['listen_address'] = '0.0.0.0:9121' postgres_exporter['listen_address'] = '0.0.0.0:9187' #gitlab_rails['gitlab_default_projects_features_builds'] = false gitlab_rails['gitlab_default_projects_features_container_registry'] = false #gitlab_rails['lfs_enabled'] = false gitlab_rails['lfs_storage_path'] = "/var/opt/git-lfs" # limit backup lifetime to 2 days - 172800 seconds gitlab_rails['backup_keep_time'] = 172800 gitlab_rails['gitlab_shell_ssh_port'] = 2224 gitlab_rails['smtp_enable'] = true; gitlab_rails['smtp_address'] = '172.17.0.1'; gitlab_rails['smtp_port'] = 25; gitlab_rails['smtp_domain'] = '172.17.0.1'; gitlab_rails['smtp_tls'] = false; gitlab_rails['smtp_openssl_verify_mode'] = 'none' gitlab_rails['smtp_enable_starttls_auto'] = false gitlab_rails['smtp_ssl'] = false gitlab_rails['smtp_force_ssl'] = false gitlab_rails['omniauth_enabled'] = false ports: - '80:80' - '443:443' - '2224:22' - '9168:9168' - '9236:9236' - '9100:9100' - '9121:9121' - '9187:9187' - '8060:8060' - '9229:9229' - '8080:8080' - '8082:8082' volumes: - '/srv/git_nfs/gitlab/config:/etc/gitlab' - '/srv/git_nfs/gitlab/logs:/var/log/gitlab' - '/srv/git_nfs/gitlab/data:/var/opt/gitlab' - '/srv/git_nfs/gitlab/secret:/secret/gitlab/backups' - '/tmp/lfs-objects:/var/opt/git-lfs' ```   Here is my prometheus.yml config file (it's a copy of the GitLab one) : ```yaml --- global: scrape_interval: 15s scrape_timeout: 15s remote_read: [] remote_write: [] scrape_configs: - job_name: prometheus static_configs: - targets: - 0.0.0.0:9090 - job_name: nginx static_configs: - targets: - IP_OF_DOCKER_HOST_FOR_GITLAB:8060 - job_name: redis static_configs: - targets: - IP_OF_DOCKER_HOST_FOR_GITLAB:9121 - job_name: postgres static_configs: - targets: - IP_OF_DOCKER_HOST_FOR_GITLAB:9187 - job_name: node static_configs: - targets: - IP_OF_DOCKER_HOST_FOR_GITLAB:9100 - job_name: gitlab-workhorse static_configs: - targets: - IP_OF_DOCKER_HOST_FOR_GITLAB:9229 - job_name: gitlab-unicorn metrics_path: "/-/metrics" static_configs: - targets: - IP_OF_DOCKER_HOST_FOR_GITLAB:8080 - job_name: gitlab-sidekiq static_configs: - targets: - IP_OF_DOCKER_HOST_FOR_GITLAB:8082 - job_name: gitlab_monitor_database metrics_path: "/database" static_configs: - targets: - IP_OF_DOCKER_HOST_FOR_GITLAB:9168 - job_name: gitlab_monitor_sidekiq metrics_path: "/sidekiq" static_configs: - targets: - IP_OF_DOCKER_HOST_FOR_GITLAB:9168 - job_name: gitlab_monitor_process metrics_path: "/process" static_configs: - targets: - IP_OF_DOCKER_HOST_FOR_GITLAB:9168 - job_name: gitaly static_configs: - targets: - IP_OF_DOCKER_HOST_FOR_GITLAB:9236 ``` Now in my Grafana, when I use the official GitLab Omnibus dashboard, all graph are not working :    Anyone can help me with that ? And how can target multiple GitLab instance in the prometheus.yml file ? Thank you very much for your help. Best regards
