    Custom SA tag in Zipkin

    +
    +

    Sometimes you want to create a manual Span that will wrap a call to an external service which is not instrumented. +What you can do is to create a span with the peer.service tag that will contain a value of the service that you want to call. +Below you can see an example of a call to Redis that is wrapped in such a span.

    +
    +
    +
    +
    org.springframework.cloud.sleuth.Span newSpan = tracer.createSpan("redis");
+try {
+	newSpan.tag("redis.op", "get");
+	newSpan.tag("lc", "redis");
+	newSpan.logEvent(org.springframework.cloud.sleuth.Span.CLIENT_SEND);
+	// call redis service e.g
+	// return (SomeObj) redisTemplate.opsForHash().get("MYHASH", someObjKey);
+} finally {
+	newSpan.tag("peer.service", "redisService");
+	newSpan.tag("peer.ipv4", "1.2.3.4");
+	newSpan.tag("peer.port", "1234");
+	newSpan.logEvent(org.springframework.cloud.sleuth.Span.CLIENT_RECV);
+	tracer.close(newSpan);
+}
    +
    +
    +
    + + + + + +
    +
    Important
    +    		 +Remember not to add both peer.service tag and the SA tag! You have to add only peer.service. +
