8/10/2023 0 Comments Splunk call rest api from search![]() More information on exporting data using the REST API. The REST API is often used by other applications to export data from Splunk via REST or to run saved searches remotely. The Splunk REST API is feature rich and allows the exporting of massive volumes of data from Splunk – although some skill is required to perform this accurately to maintain data integrity. The Splunk REST API can be used to export data from any Splunk environment, including on-premise and cloud deployments. Data can be exported in JSON, CSV or XML formats. The REST API can be leveraged to execute saved searches or to perform ad-hoc searches. Splunk REST APIĪ user can call the Splunk REST API to export search results. It is important to execute care when implementing forwarding to other systems, to ensure Splunk queues do not back up and the data being forwarding is accurate and complete. execute a Splunk search and forward the results on). ![]() as the data is indexed into Splunk) or at search time (i.e. Data can be forwarded from Splunk at index time (i.e. This can also be accomplished through Splunk apps, such as the Splunk App for CEF, which syslogs data in CEF format. Splunk Forwardingīy making revisions to the outputs, props and transforms configuration files, Splunk can be made to forward or stream data to a third-party application using any available network port using a standard syslog format. More information on using the Splunk GUI to export data. The capability to export data in this way may also be limited, depending on user access controls that have been set by your administrator. However, they are great way to export reports or result sets. One of the main issues with all these GUI based exporting approaches is that they typically do not allow for exporting of massive amounts of data. The dump search command can also be used to perform a oneshot export of search results to the local disk in the following directory: $SPLUNK_HOME/var/run/splunk/dispatch//dump. Another useful search command is outputcsv, which will store the search results into a CSV on the Search Head in the following directory: $SPLUNK_HOME/var/run/splunk/csv. In addition, search results can be e-mailed through alert actions or by executing the sendemail search command. Data can be exported to as a text file containing the raw events or exported in tabulated/structured CSV, XML or JSON formats. Remotely execute Splunk searches and export the resultsĭefine custom callbacks on a web resourceĬonnect third-party analytics tools to Splunk via ODBC to export dataĪ user can export results of a search directly from the Splunk GUI. MethodĬonfigure Splunk to stream data out of Splunk to a third-party application Each method is then explained further below. The following table provides a summary of methods that can be used to get data out of Splunk. In a related post, we outline some of the many ways to get data into Splunk.ĭiscovered Intelligence has implemented all the output methods outlined below for customers. In this post, we will outline some of the many methods you can use to get data out of Splunk. Once completed, I conducted tests by also running the searches via the REST API so I have documented that method as well.There are several ways of integrating Splunk within your environment or with your cloud service providers. I wanted to implement the gathering of results with a cron-scheduled bash script, so I decided to write the script with the scheduled search method. We can run the search on a schedule and then pull the results right away, or we can pull the results of a scheduled saved search. We can accomplish my goal one of two ways. The local Splunk instance is running on IP address 192.168.0.70 with the default REST interface running HTTPS on TCP 8089. This data is already indexed on my local Splunk instance so all I have to do is search for it. One of the things I wanted to display was the count of accepted and blocked connections through my firewall. I don’t think they had a good proof of concept that showed a fully working use case however, their documentation on all the available features is quite in-depth: ![]() I was able to complete this task utilizing the documentation that Splunk has provided for searching via the REST API. Therefore, I wanted a way to display all of the data with the console. This display board would be simple enough to just present a number of Splunk dashboards on the display, while being able to avoid running a window environment, web browser, and all of the associated overhead on my relatively weak Pi Zero W. As a way to justify essentially useless equipment around my house, I wanted to make a Raspberry Pi driven display board.
