Now the fields have been given the general names column1, column2 and column3. We can demonstrate this by removing the first line from the example file and uploading it again. In this case, the find_file_structure endpoint will use temporary field names. This is all very well for a CSV file which has a header, but what if the data does not contain a header row at the top? For responsetime, which has been identified as being a numerical field the min, median and max values are also displayed. We can see that the types of the three fields have been correctly identified, with some high level statistics listed for each one. The top 10 occuring values are listed for each field. Underneath this Summary section is the fields section, this should be familiar with people who have used the original Data Visualizer feature. The first column has matched a known date format and so is highlighted as being the Time field. It has also detected that there is a header row, and has used these field names to label the data in each column. When we select the CSV file, the page sends the first 1000 lines from the file to the find_file_structure endpoint which runs its analysis and returns back its findings. Looking at the Summary section in the UI we can see that it has correctly detected that the data is in a delimited format and that the delimiter is a comma character. As of 6.5, we’re limited to a maximum file size of 100MB. The user is presented with a page which allows them to select or drag and drop a file. The File Data Visualizer feature can be found in Kibana under the Machine Learning > Data Visualizer section. Here we’re showing only the first five lines of the file to give you an idea of what the data looks like:Ĭonfigure the CSV Import within File Data Visualizer The following example will use data from a CSV file containing imaginary data from a flight booking website. The best way to demonstrate this functionality is to step through an example. Using the File Data Visualizer he was easily able to import earthquake data into Elasticsearch to help him explore and analyse earthquake locations using geo_point visualizations in Kibana.Įxample: Importing a CSV File into Elasticsearch The aim of this feature is to enable users who wish to explore their data with Kibana or Machine Learning to easily get small amounts of data into Elasticsearch without having to learn the intricacies of the ingest process.Ī great recent example is this blog post by a member of Elastic’s marketing team, who doesn’t have a development background. This includes a suggested ingest pipeline and mappings which can be used to import the file into elasticsearch from the UI. log files) where the new Elastic machine learning find_file_structure endpoint will analyse it and report back its findings about the data. CSV), NDJSON or semi-structured text (e.g. This new feature allows a user to upload a file containing delimited (e.g. Introduced in Elastic Stack 6.5 is the new File Data Visualizer feature.
