Find and index data
Add Data
Adding data inputs to Splunk is easy and there are many methods for getting your data into Splunk. You can add data via SplunkWeb, Splunk's CLI, scripts and 3rd party software. To get started quickly and simply, you can immediately begin tailing a file in a log file directory, such as /var/log.
When you first access SplunkWeb, there is a helpful action link to begin tailing /var/log locally:
There are many other ways to set up data inputs into Splunk. This section is a high-level description of these techniques. For more detailed methods, see the data inputs section.
Tail a file
When you specify a file to tail, Splunk will process the entire file and then watch and process additions to the file. When you give a directory name to process, Splunk recursively searches all subdirectories looking for files resembling log files. You can explicitly include or exclude files with whitelisting and blacklisting.
Tailing files via the SplunkWeb Admin Interface
- Click the Data Inputs tab.
- The first row is the Files and Directories option. Click the Add input link under the Action heading.
- Under the Source heading
- Select Tail from the Data Access drop-down.
- Type in the path to the file in the text box.
Tailing files via the CLI
Use the splunk add command. These commands assume you have set a Splunk environment variable. If you have not, you must navigate to $SPLUNK_HOME/bin and run the ./splunk command.
For example:
splunk add tail /var/log/
This command tails all files in /var/log/.
Find logfiles
Splunk has a built-in command to search for potential log files to index. From the Splunk CLI, type:
splunk find logs "searchpath1;searchpath2;..."
This command will search for logs in any number of searchpaths.
The details of which directories and file types are ignored, as well as file size and modification date restrictions are defined in $SPLUNK_HOME/etc/findlogs.ini.
After logs are found, you will have the option of indexing some, all, or none of the files. If you answer Some, you will be prompted file-by-file.
Get help configuring your sources
New data sources can crop up daily. If you do not see the means to configure a data source to send the data you want to Splunk, be sure to look on SplunkBase or contact Splunk Support.
