Zipkin
DataKit 内嵌的 Zipkin Agent 用于接收,运算,分析 Zipkin Tracing 协议数据。
配置¶
采集器配置¶
进入 DataKit 安装目录下的 conf.d/zipkin
目录,复制 zipkin.conf.sample
并命名为 zipkin.conf
。示例如下:
[[inputs.zipkin]]
pathV1 = "/api/v1/spans"
pathV2 = "/api/v2/spans"
## ignore_tags will work as a blacklist to prevent tags send to data center.
## Every value in this list is a valid string of regular expression.
# ignore_tags = ["block1", "block2"]
## Keep rare tracing resources list switch.
## If some resources are rare enough(not presend in 1 hour), those resource will always send
## to data center and do not consider samplers and filters.
# keep_rare_resource = false
## delete trace message
# del_message = true
## Ignore tracing resources map like service:[resources...].
## The service name is the full service name in current application.
## The resource list is regular expressions uses to block resource names.
## If you want to block some resources universally under all services, you can set the
## service name as "*". Note: double quotes "" cannot be omitted.
# [inputs.zipkin.close_resource]
# service1 = ["resource1", "resource2", ...]
# service2 = ["resource1", "resource2", ...]
# "*" = ["close_resource_under_all_services"]
# ...
## Sampler config uses to set global sampling strategy.
## sampling_rate used to set global sampling rate.
# [inputs.zipkin.sampler]
# sampling_rate = 1.0
# [inputs.zipkin.tags]
# key1 = "value1"
# key2 = "value2"
# ...
## Threads config controls how many goroutines an agent cloud start to handle HTTP request.
## buffer is the size of jobs' buffering of worker channel.
## threads is the total number fo goroutines at running time.
# [inputs.zipkin.threads]
# buffer = 100
# threads = 8
## Storage config a local storage space in hard dirver to cache trace data.
## path is the local file path used to cache data.
## capacity is total space size(MB) used to store data.
# [inputs.zipkin.storage]
# path = "./zipkin_storage"
# capacity = 5120
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。
