Couchbase
Couchbase 采集器用于采集 Couchbase 服务器相关的指标数据。
Couchbase 采集器支持远程采集，可以运行在多种操作系统中。
已测试的版本：
- Couchbase enterprise-7.2.0
- Couchbase community-7.2.0
配置¶
前置条件¶
- 安装 Couchbase 服务
- 验证是否正确安装
在浏览器访问网址 <ip>:8091 可以进入 Couchbase 管理界面。
Tip
- 采集数据需要用到
809191021809119102几个端口，远程采集的时候，被采集服务器这些端口需要打开。
采集器配置¶
进入 DataKit 安装目录下的 conf.d/couchbase 目录，复制 couchbase.conf.sample 并命名为 couchbase.conf。示例如下：
[[inputs.couchbase]]
## Collect interval, default is 30 seconds. (optional)
# interval = "30s"
## Timeout: (defaults to "5s"). (optional)
# timeout = "5s"
## Scheme, "http" or "https".
scheme = "http"
## Host url or ip.
host = "127.0.0.1"
## Host port. If "https" will be 18091.
port = 8091
## Additional host port for index metric. If "https" will be 19102.
additional_port = 9102
## Host user name.
user = "Administrator"
## Host password.
password = "123456"
## TLS configuration.
tls_open = false
# tls_ca = ""
# tls_cert = "/var/cb/clientcertfiles/travel-sample.pem"
# tls_key = "/var/cb/clientcertfiles/travel-sample.key"
## Disable setting host tag for this input
disable_host_tag = false
## Disable setting instance tag for this input
disable_instance_tag = false
## Set to 'true' to enable election.
election = true
# [inputs.couchbase.tags]
# some_tag = "some_value"
# more_tag = "some_other_value"
配置好后，重启 DataKit 即可。
可通过 ConfigMap 方式注入采集器配置 或 配置 ENV_DATAKIT_INPUTS 开启采集器。
也支持以环境变量的方式修改配置参数（需要在 ENV_DEFAULT_ENABLED_INPUTS 中加为默认采集器）：
