External¶
External 采集器可以启动外部程序进行采集。
配置¶
前置条件¶
- 启动命令的程序及其运行环境的依赖完备。比如用 Python 去启动外部 Python 脚本，则该脚本运行所需的引用包等依赖必须要有。
采集器配置¶
进入 DataKit 安装目录下的 conf.d/external 目录，复制 external.conf.sample 并命名为 external.conf。示例如下：
[[inputs.external]]
# Collector's name.
name = 'some-external-inputs' # required
# Whether or not to run the external program in the background.
daemon = false
# If the external program running in a Non-daemon mode,
# runs it in every this interval time.
#interval = '10s'
# The environment variables running the external program.
#envs = ['LD_LIBRARY_PATH=/path/to/lib:$LD_LIBRARY_PATH',]
# The external program' full path. Filling in absolute path whenever possible.
cmd = "python" # required
# Filling "true" if this collecor is involved in the election.
# Note: The external program must running in a daemon mode if involving the election.
election = false
args = []
[[inputs.external.tags]]
# tag1 = "val1"
# tag2 = "val2"
配置好后，重启 DataKit 即可。
目前可以通过 ConfigMap 方式注入采集器配置来开启采集器。
