Hi Balaiya
Gald you join me in this way. I need the following info 1. Why version are you using? Our beta release, or branch master built by yourself. 2. Have you set application.yml right? Such as: ElasticSearch related settings.By following our documents: https://github.com/apache/incubator-skywalking/blob/master/docs/README.md 3. This is the expected output in log: 2018-05-29 14:48:05,439 - org.apache.skywalking.apm.collector.client.elasticsearch.ElasticSearchClient -4943 [main] INFO [] - elasticsearch cluster nodes: localhost:9300 Your logs show: org.apache.skywalking.apm.collector.client.elasticsearch.ElasticSearchClient -9093 [main] INFO [] - elasticsearch cluster nodes: null My guess, you don't start up or set your elastic search right.
