+# Metric Exporter
+SkyWalking provides basic and most important metric aggregation, alarm and analysis.
+In real world, people may want to forward the data to their 3rd party system, for deeper analysis or anything else.
+**Metric Exporter** makes that possible.
+
+Metric exporter is an independent module, you need manually active it.
+
+Right now, we provide the following exporters
+1. gRPC exporter
+
+## gRPC exporter
+gRPC exporter uses SkyWalking native exporter service definition. Here is proto definition.
+```proto
+service MetricExportService {
+ rpc export (stream ExportMetricValue) returns (ExportResponse) {
+ }
+
+ rpc subscription (SubscriptionReq) returns (SubscriptionsResp) {
+ }
+}
+
+message ExportMetricValue {
+ string metricName = 1;
+ string entityName = 2;
+ string entityId = 3;
+ ValueType type = 4;
+ int64 timeBucket = 5;
+ int64 longValue = 6;
+ double doubleValue = 7;
+}
+
+message SubscriptionsResp {
+ repeated string metricNames = 1;
+}
+
+enum ValueType {
+ LONG = 0;
+ DOUBLE = 1;
+}
+
+message SubscriptionReq {
+
+}
+
+message ExportResponse {
+}
+```
+
+To active the exporter, you should add this into your `application.yml`
+```yaml
+exporter:
+ grpc:
+ targetHost: 127.0.0.1
+ targetPort: 9870
+```
+
+- `targetHost`:`targetPort` is the expected target service address. You could set any gRPC server to receive the data.
+- Target gRPC service needs to be standby, otherwise, the OAP starts up failure.
+
+## For target exporter service
+### subscription implementation
+Return the expected metric name list, all the names must match the OAL script definition. Return empty list, if you want
+to export all metrics.
+
+### export implementation
+Stream service, all subscribed metrics will be sent to here, based on OAP core schedule. Also, if the OAP deployed as cluster,
+then this method will be called concurrently. For metric value, you need follow `#type` to choose `#longValue` or `#doubleValue`.
