Version 3.x -> 5.0.0-alpha Upgrade FAQs

Collector

Problem

There is no information showing in the UI.

Cause

In upgrate from 3.2.6 to 5.0.0, Elasticsearch indexes aren’t recreated, because not indexes exist, but aren’t compatible with 5.0.0-alpha. When service name registered, the es will create this column by default type string, which is wrong.

Solution

Clean the data folder in ElasticSearch and restart ElasticSearch, collector and your under monitoring application.
