Introducing Dev Tools

Dev Tools is an important feature of Kibana where we have a console for running Elasticsearch queries, a search profiler to profile the Elasticsearch query, and Grok Debugger to create a grok pattern for extracting fields from unstructured data, such as log files. For accessing the Elasticsearch index in Kibana, we need to create the index pattern; however, using the Dev Tools console, we can directly run queries on any index of Elasticsearch.

The search profiler of Dev Tools provides details of each query with the query duration for each component of the query, along with the percentage of time consumed for each component. We can optimize the queries using this detail if any component is taking a long time.

Now we will cover these three features of Dev Tools in detail.
