Depending on the target system tech stack, there are very different ways how the probe performs such tasks. But ultimately, they all work towards the same goal — to collect and reformat data, and then to send them to the backend.

 <meta itemprop="description" content="Version 3.x -&gt; 5.0.0-alpha Upgrade FAQs Collector Problem There is no information showing in the UI.
 Cause In the upgrade from version 3.2.6 to 5.0.0, the existing Elasticsearch indexes are kept, but aren&rsquo;t compatible with 5.0.0-alpha. When service name is registered, ElasticSearch will create this column by default type string, which will lead to an error.
 Solution Clean the data folder in ElasticSearch and restart ElasticSearch, collector and your application under monitoring.">
