**Kibana version** : 7.3.2

**Elasticsearch version** : 7.3.2

**APM Server version** : 7.3.2

**APM Agent language and version** : java 1.9.0

**Fresh install or upgraded from other version?** fresh install

**Is there anything special in your setup?** For example, are you using the Logstash or Kafka outputs? Are you using a load balancer in front of the APM Servers? Have you changed index pattern, generated custom templates, changed agent configuration etc. :-----No

**Description of the problem including expected versus actual behavior. Please include screenshots (if relevant)** :

**Steps to reproduce** :

I am tracing my spans in Kibana using open tracing. But I have some actions which I don't want to create them as spans . I just need to capture them as events , which is exactly what the span.log api from opentracing does. But how can I visualize them in Kibana. Where exactly can I view the event that I have added into the logs

FOR EXAMPLE childSpan.log(System.currentTimeMillis()\*1000, "testing event"); I checked Kibana to see "testing event" , but couldn't locate it.

To be more precise how can we log events using Elastic APM opentracing bridge or set an the action related to a span using the open tracing bridge

Please see the caveats section of the OpenTracing bridge docs:

> **[OpenTracing bridge | APM Java Agent Reference \[1.x\] | Elastic](https://www.elastic.co/guide/en/apm/agent/java/current/opentracing-bridge.html#logs)**

(This feature is not supported, apart from error logs.)
