Add or edit a virtual index in Splunk Web
You can also add HDFS providers and virtual indexes by editing. See Set up a virtual index in the configuration file for instructions on setting up virtual indexes in the configuration file.
1. Select Settings > Virtual Indexes.
2. Click the Virtual Indexes tab and click New Virtual Index or click the name of the index you want to edit. The New/Edit Virtual Index page appears:
3. In the Name field, provide a name for your virtual index.
4. Select a Provider. To add a new provider, see Add an HDFS provider.
5. Provide the following path information:
- Path to data in HDFS: This is the path to the data that Splunk Analytics for Hadoop will be accessing and reporting on. For example:
- Recursively process the directory: Check this if you want to (recursively) include the content of sub directories.
- Whitelist: Provide a regex that matches the file path. You can specify regular expressions to filter in/out files (based on the full path) that should/not be considered part of the virtual index. A common use case for using it is to ignore temporary files, or files that are currently being written to. Keep in mind that ignore takes precedence over accept. For example:
6. Check Customize timestamp format to open the controls that allow you to customize how data is collected based on timestamp information. Use simple date format to optionally customize the following:
- Time capturing Regex: Provide a regex that determines the earliest date/time that will be collected and processed based on timestamp. For example:
- Time Format: For the earliest time above, provide a time format that describes how to interpret the extracted time string. For example:
- Time Adjustment: Amount of time, in seconds, to add to the earliest time. Example (+7hrs): 25200
- Time Range: Provide a time range for which the index should collect data.
- Time Zone: Select your time zone.
