# Monitoring HAProxy > 原文：[https://docs.gitlab.com/ee/user/project/integrations/prometheus_library/haproxy.html](https://docs.gitlab.com/ee/user/project/integrations/prometheus_library/haproxy.html) * [Requirements](#requirements) * [Metrics supported](#metrics-supported) * [Configuring Prometheus to monitor for HAProxy metrics](#configuring-prometheus-to-monitor-for-haproxy-metrics) * [Specifying the Environment label](#specifying-the-environment-label) # Monitoring HAProxy[](#monitoring-haproxy "Permalink") 在 GitLab 9.4 中[引入](https://gitlab.com/gitlab-org/gitlab-foss/-/merge_requests/12621) GitLab 支持自動檢測和監視 HAProxy. 這是通過利用[HAProxy Exporter](https://github.com/prometheus/haproxy_exporter)來提供的，后者將 HAProxy 統計信息轉換為 Prometheus 可讀形式. ## Requirements[](#requirements "Permalink") 必須啟用[Prometheus 服務](../prometheus.html) . ## Metrics supported[](#metrics-supported "Permalink") | Name | Query | | --- | --- | | 吞吐量（要求/秒） | `sum(rate(haproxy_frontend_http_requests_total{%{environment_filter}}[2m])) by (code)` | | HTTP 錯誤率（％） | `sum(rate(haproxy_frontend_http_requests_total{code="5xx",%{environment_filter}}[2m])) / sum(rate(haproxy_frontend_http_requests_total{%{environment_filter}}[2m]))` | ## Configuring Prometheus to monitor for HAProxy metrics[](#configuring-prometheus-to-monitor-for-haproxy-metrics "Permalink") 要開始使用 NGINX 監視，您應該安裝并配置[HAProxy 導出程序](https://github.com/prometheus/haproxy_exporter) ，該程序可以解析這些統計信息并將其轉換為 Prometheus 監視端點. ## Specifying the Environment label[](#specifying-the-environment-label "Permalink") 為了隔離并僅顯示給定環境的相關指標，GitLab 需要一種方法來檢測關聯了哪些標簽. 為此，GitLab 將[查找`environment`標簽](index.html#identifying-environments) .
