Output_line += ','.join(scan_source_data) Scan_duration = time.time()-scan_start_time Hits = scan(elastic_client, index=index, query=query, scroll='20h', clear_scroll=True, size=5000) With open('/tmp/scandocs.csv','w') as f_out: If it is the scan then you might be out of luck. Thanks.Įdit adding timing print statements to see if the scan call is slow, or the for loop is slow. I'm unable to find an optimised way to resolve this. I'm a newbie to python world and doesn't know much about it, but I'm sure there must be some better way. ![]() While trying to export 200,000 records I get time gap of 1 hour between two scroll queries run in the logs and was running for more than 24 hours. I tried exporting around 50,000 records in one go it took around one and half hour to get the CSV. POST Īs you can see first 5000 chunk took 3 minutes, next 5000 chunk took 4 minutes, next one 6 minutes, next 8 minutes and this time increases when the size of the append increases. Scan_docs = scan_docs.append(scan_doc_data) Scan_doc_data = pandas.Series(scan_source_data, name=scan_id) My code looks like: for hit in scan(elastic_client, index=index, query=query, scroll='20h', clear_scroll=True, size=5000): To achieve this I'm using scan helper function and split it into 5000 chunks, I'm able to extract all the elasticsearch data with infinite scroll with this It is taking too much of time in execution, while checking the logs I see that pandas is taking too much of time while appending the data. I'm taking about minimum of 1 million of records which needs to be exported. If you enjoyed this guide on how to export data from a Kibana search then why not check out our article on how to create a new Elastalert rule as well as our article on how to remove fields using Logstash filters.I'm trying to export large set of elasticsearch query results to csv with pandas. To get started with using Logit.io simply sign up to our platform and get 14-days of free access to create as many stacks as you require. If you are getting started with using Kibana for the first time then it is likely that you'll require a platform in order to host your Elasticsearch cluster.īy using a platform such as Logit.io, you can experience all of the benefits of fully open ELK without having to configure, maintain or manually upgrade your Stack. Then you will be able to export it by checking the check box next to its name and pressing the Export button. If you save a visualisation from the Visualisations menu, it will show in the list of saved objects. This can be used to backup data and then imported at any time using the import button in the top right of the page next to the refresh button, as shown below: This page allows you to selectively export one or more objects contained inside a single "export.json" file. You can filter by the type of export using the Types dropdown menu on the right of the search box. You can export saved dashboards, search results, visualisations and more inside the Saved Objects submenu. Kibana provides the capabilities to export saved objects created by the user using the Management menu. The raw version will show more specific values for numbers and the date/time values will used timestamps rather than easy to read labels (i.e. See the screenshot below:īoth the raw and formatted options will export a CSV file and include headers using the CSV data format, however the latter option will format data rows in a more human-readable format, similar to the data shown in the results panel. You cannot export a visualisation if there is no data within the visualisation, and as such the inspect button will be disabled.Ī right side inspection window will show where you will be able to select the type of CSV to download. In order to export a visualisation to a formatted CSV file, you must first open up a visualisation from the Visualisations menu and press the Inspect button at the top of the page. If you want to learn how to export your Kibana dashboards, visualisations, and search results as either CSV or JSON then follow the steps below in our brief guide.
