Red Hat Quay 提供了有助于监控 registry 的指标,包括常规 registry 使用的指标、上传、下载、垃圾回收和身份验证。

13.2.1. 常规 registry 统计

常规 registry 统计可指示 registry 的增长量。

指标名称描述

数据库中的机器人帐户数

quay_org_rows

数据库中的机构数量

quay_repository_rows

数据库中的存储库数

未被最新安全扫描程序扫描的镜像数

指标输出示例

# HELP quay_user_rows number of users in the database
# TYPE quay_user_rows gauge
quay_user_rows{host="example-registry-quay-app-6df87f7b66-9tfn6",instance="",job="quay",pid="65",process_name="globalpromstats.py"} 3

# HELP quay_robot_rows number of robot accounts in the database
# TYPE quay_robot_rows gauge
quay_robot_rows{host="example-registry-quay-app-6df87f7b66-9tfn6",instance="",job="quay",pid="65",process_name="globalpromstats.py"} 2

# HELP quay_org_rows number of organizations in the database
# TYPE quay_org_rows gauge
quay_org_rows{host="example-registry-quay-app-6df87f7b66-9tfn6",instance="",job="quay",pid="65",process_name="globalpromstats.py"} 2

quay_security_scanning_unscanned_images_remaining{host="example-registry-quay-app-6df87f7b66-9tfn6",instance="",job="quay",pid="208",process_name="secscan:application"} 5

13.2.2. 队列项

队列项目 指标提供有关 Quay 用来管理工作的多个队列的信息。

指标名称描述

quay_queue_items_available

特定队列中的项目数

quay_queue_items_locked

正在运行的项目数

quay_queue_items_available_unlocked

等待处理的项目数

指标标签

  • queue_name : 队列的名称。其中之一:

    • exportactionlogs : 排队请求以导出操作日志。这些日志随后会被处理并放入存储中。然后,通过电子邮件将链接发送到请求者。
    • namespacegc: 要收集的垃圾命名空间
    • 通知: 要发送存储库通知队列
    • repositorygc: 要收集垃圾收集的队列存储库
    • secscanv4: 特定于 Clair V4 的通知队列
    • dockerfilebuild: Quay docker 构建队列
    • Imagestoragereplication : 要在多个存储间复制排队 Blob
    • chunk_cleanup : 需要删除队列 Blob 段。这仅适用于某些存储实施,如 Swift。

例如,queue labelled repositorygc 包含由存储库垃圾回收 worker 标记的存储库。对于带有 queue_name 标签为 repositorygc 的指标:

  • quay_queue_items_locked 是当前删除的存储库数。
  • quay_queue_items_available_unlocked 是 worker 等待处理的存储库数量。

指标输出示例

# HELP quay_queue_items_available number of queue items that have not expired
