SkyWalking Configurations mostly are set through application.yml
and OS system environment variables. But some of them are supporting dynamic settings from upstream management system.
Right now, SkyWalking supports following dynamic configurations.
Config Key | Value Description | Value Format Example |
---|---|---|
receiver-trace.default.slowDBAccessThreshold | Thresholds of slow Database statement, override receiver-trace/default/slowDBAccessThreshold of applciation.yml . | default:200,mongodb:50 |
receiver-trace.default.uninstrumentedGateways | The uninstrumented gateways, override gateways.yml . | same as gateways.yml |
alarm.default.alarm-settings | The alarm settings, will override alarm-settings.yml . | same as alarm-settings.yml |
core.default.apdexThreshold | The apdex threshold settings, will override service-apdex-threshold.yml . | same as service-apdex-threshold.yml |
This feature depends on upstream service, so it is OFF as default.

Dynamic Configuration Service is a gRPC service, which requires the upstream system implemented. The SkyWalking OAP fetches the configuration from the implementation(any system), after you open this implementation like this.
configuration: grpc: # Upstream system hostname host: 127.0.0.1 # Upstream system port port: 9555 #period : 60 # Unit seconds, sync period. Default fetch every 60 seconds. #clusterName: "default" # the name of current cluster, set the name if you want to upstream system known.
Apollo is also supported as DCC(Dynamic Configuration Center), to use it, just configured as follows:
configuration: apollo: apolloMeta: <your apollo meta address> apolloCluster: default # apolloEnv: # defaults to null appId: skywalking period: 5
Nacos is also supported as DCC(Dynamic Configuration Center), to use it, please configure as follows:
configuration: nacos: # Nacos Server Host serverAddr: 127.0.0.1 # Nacos Server Port port: 8848 # Nacos Configuration Group group: 'skywalking' # Nacos Configuration namespace namespace: '' # Unit seconds, sync period. Default fetch every 60 seconds. period : 60 # the name of current cluster, set the name if you want to upstream system known. clusterName: "default"
Zookeeper is also supported as DCC(Dynamic Configuration Center), to use it, please configure as follows:
configuration: zookeeper: period : 60 # Unit seconds, sync period. Default fetch every 60 seconds. nameSpace: /default hostPort: localhost:2181 #Retry Policy baseSleepTimeMs: 1000 # initial amount of time to wait between retries maxRetries: 3 # max number of times to retry
Etcd is also supported as DCC(Dynamic Configuration Center), to use it, please configure as follows:
configuration: etcd: period : 60 # Unit seconds, sync period. Default fetch every 60 seconds. group : 'skywalking' serverAddr: localhost:2379 clusterName: "default"
Consul is also supported as DCC(Dynamic Configuration Center), to use it, please configure as follows:
configuration: consul: # Consul host and ports, separated by comma, e.g. 1.2.3.4:8500,2.3.4.5:8500 hostAndPorts: 127.0.0.1:8500 # Sync period in seconds. Defaults to 60 seconds. period: 60
