NSQ
采集 NSQ 运行数据并以指标的方式上报到观测云。
配置¶
前置条件¶
推荐 NSQ 版本 >= 1.0.0,已测试的版本:
- 1.2.1
- 1.1.0
- 0.3.8
采集器配置¶
进入 DataKit 安装目录下的 conf.d/nsq
目录,复制 nsq.conf.sample
并命名为 nsq.conf
。示例如下:
[[inputs.nsq]]
## NSQ Lookupd HTTP API endpoint
lookupd = "http://localhost:4161"
## NSQD HTTP API endpoint
## example:
## ["http://localhost:4151"]
nsqd = []
## time units are "ms", "s", "m", "h"
interval = "10s"
## Set true to enable election
election = true
## Optional TLS Config
# tls_ca = "/etc/telegraf/ca.pem"
# tls_cert = "/etc/telegraf/cert.pem"
# tls_key = "/etc/telegraf/key.pem"
## Use TLS but skip chain & host verification
# insecure_skip_verify = false
[inputs.nsq.tags]
# some_tag = "some_value"
# more_tag = "some_other_value"
配置好后,重启 DataKit 即可。
NSQ 采集器提供两种配置方式,分别为 lookupd
和 nsqd
lookupd
:配置 NSQ 集群的lookupd
地址,采集器会自动发现 NSQ Server 并采集数据,扩展性更佳nsqd
:配置固定的 NSQ Daemon(nsqd
)地址列表,采集器只会采集该列表的 NSQ Server 数据
以上两种配置方式是互斥的,lookupd
优先级更高,推荐使用 lookupd
配置方式。
目前可以通过 ConfigMap 方式注入采集器配置来开启采集器。
指标¶
以下所有数据采集,默认会追加全局选举 tag,也可以在配置中通过 [inputs.nsq.tags]
指定其它标签:
