Kibana is a powerful visualization and exploration tool designed to work with Elasticsearch. It allows users to create visualizations, dashboards, and manage data through an intuitive interface. One of its features, 'Runtime Fields', enables users to define fields that are computed at query time, providing flexibility in data analysis without altering the underlying data.
When using Kibana, you might encounter an issue where 'Runtime Fields' are not functioning as expected. This can manifest as missing fields in visualizations, incorrect data being displayed, or errors during query execution.
The problem often arises from incorrect configuration of runtime fields or issues with the data source. Runtime fields are defined using scripts, and any syntax errors or logical mistakes can lead to failures. Additionally, if the data source is unavailable or misconfigured, it can prevent runtime fields from being evaluated correctly.
Ensure that the script used for defining the runtime field is correct and adheres to the Elasticsearch runtime field syntax. Common mistakes include incorrect field names, unsupported operations, or syntax errors.
Follow these steps to troubleshoot and resolve issues with Kibana's runtime fields:
curl -X GET "localhost:9200/_cluster/health?pretty".By carefully reviewing the configuration of runtime fields and ensuring the data source is operational, you can resolve most issues related to Kibana's runtime fields.
