statsd / Graphite Integration

When using nsqd --statsd-address=... you can specify a nsqadmin --graphite-url=http://graphite.yourdomain.com to enable graphite charts in nsqadmin. If using a statsd clone (like statsdaemon) that does not prefix keys, also specify --use-statsd-prefix=false.

当使用 nsqd --statsd-address=... 您可以指定一个 nsqadmin --graphite-url=http://graphite.yourdomain.com 来启用 nsqadmin中的graphite 图表。如果使用没有前缀键的statsd克隆(如statsdaemon)，也要指定 --use-statsd-prefix=false。

Admin Notifications

Admin 通知

If the --notification-http-endpoint flag is set, nsqadmin will send a POST request to the specified (fully qualified) endpoint each time an admin action (such as pausing a channel) is performed.

如果设置了 --notification-http-endpoint标志，那么每次执行管理操作(例如暂停通道)时，nsqadmin将向指定的(完全限定的)端点发送POST请求。

The body of the request contains information about the action (some fields will be omitted when appropriate), like so:

请求的主体包含有关操作的信息(在适当的时候会省略一些字段)，如下:

{
  "action": "unpause_channel",
  "channel": "mouth",
  "topic": "beer",
  "timestamp": 1357683731,
  "user": "df",
  "user_agent": "Mozilla/5.0 (Macintosh; Iphone 8)",
  "remote_ip": "1.2.3.4:5678",
  "url": "http://nsqadmin.local/api/topics/api_requests/nsq_to_file",
  "via": "localhost"
}

The user field will be filled if a HTTP Basic Authentication Username is present in the request made to nsqadmin, say if it were running with htpasswd authentication or behind oauth2_proxy.

如果在向nsqadmin发出的请求中出现HTTP基本身份验证用户名，则 user 字段将被填充，比如它是在htpasswd身份验证下运行的，或者在[' oauth2_proxy ']后面运行(https://github.com/bitly/oauth2_proxy#oauth2_proxy)。

htpasswd: 建立和更新存储用户名、密码的文本文件， 用于对HTTP用户的basic认证。

Hint: You can create an NSQ stream of admin action notifications with the topic name admin_actions by setting --notification-http-endpoint to point to the nsqd HTTP Publish API. For example if running nsqd on the same node you could use --notification-http-endpoint="http://127.0.0.1:4151/put?topic=admin_actions"

​ 提示： 您可以创建一个主题名为 admin_actions 的NSQ管理操作通知流，方法是设置 --notification-http-endpoint 指向 nsqd HTTP Publish API。例如，如果在同一个节点上运行nsqd，可以使用--notification-http-endpoint="http://127.0.0.1:4151/put?topic=admin_actions"

There are community contributed utilities nsqadmin2slack and nsqadmin2hipchat to relay messages to HipChat and Slack respectively.

有社区提供的实用程序nsqadmin2slack和nsqadmin2hipchat 分别向HipChat和Slack传递消息。

Metrics

测试

The following metrics are exposed through nsqadmin on Topic, Channel and Client Connections.

以下指标通过 nsqadmin 公开主题、通道和客户端连接。

Message Queues:

消息队列

  • Depth: Current sum of messages in memory + on disk (i.e. the “backlog” of messages pending delivery).

“深度”:内存+磁盘上消息的当前总数(即待发消息的“积压”)。

  • In-Flight: Current count of messages delivered but not yet finished (FIN), requeued (REQ) or timed out.

“飞行中”:当前发送但尚未完成的消息数(' FIN ')、重新请求的消息数(' REQ ')或超时的消息数。

  • Deferred: Current count of messages that were requeued and explicitly deferred which are not yet available for delivery.

“延迟”:当前已请求并显式延迟的消息数量，这些消息目前还不能交付。

Statistics:

统计

  • Requeued: Total times a message has been added back to the queue due to time outs or explicit requeues.

由于超时或显式请求，消息被添加回队列的总次数。

  • Timed Out: Total times a message has been requeued after not receiving a response from the client before the configured timeout.

在配置超时之前没有收到来自客户机的响应后，请求消息的总时间。

  • Messages: Total count of new messages recieved since node startup.

自节点启动以来接收的新消息总数。

  • Rate: The per-second rate of new messages over the previous two statsd intervals (available only when graphite integration is enabled).

前两个statsd间隔的每秒新消息速率(仅在启用graphite 集成时可用)。

  • Connections: Current number of connected clients.

当前已连接的客户端数量。

Client Connections:

客户端链接

  • Client Host: Client ID (hostname) and on-hover the connection remote-address.

客户端ID(主机名)和on-hover连接远程地址。

  • Protocol: NSQ protocol version and client user-agent.

NSQ协议版本和客户端用户代理。

  • Attributes: TLS and AUTH connection state.

TLS和AUTH连接状态。

  • NSQd Host: Address of the nsqd node this client is connected to.

此客户端连接到的nsqd节点的地址。

  • In-flight: Current count of messages awaiting response that have been delivered to this client.

等待已发送到此客户机的响应的消息的当前计数。

  • Ready Count: Max number of messages that can be in-flight on this connection. This is controlled by a client’s max_in_flight setting.

在此连接上可以运行的最大消息数。这由客户机的max_in_flight设置控制。

  • Finished: Total count of messages that this client has finished (FIN).

此客户端已完成的消息总数(' FIN ')。

  • Requeued: Total count of messages that this client has requeued (REQ).

此客户端已请求的消息总数(' REQ ')。

  • Messages: Total count of messages delivered to this client.

发送到此客户机的消息总数。
