1.Using Delete Command In Splunk, the delete command is used to mark events as deleted from search results. However, it does not physically remove the events from disk or from the index. Instead, it hides the marked events so they are not returned in future search results. The events are still present in the index but flagged as deleted 2. Permanently Delete Data via Index Cleanup (Retention Policies) To physically delete data from Splunk's indexes, you typically rely on index retention policies. Splunk automatically deletes older data based on index size or time-based retention policies. Set Index Retention Policies: Maximum Size (based on disk usage): Once the index exceeds a defined size, Splunk will delete the oldest data. Time-based Retention: Splunk can automatically remove data that is older than a specific period (e.g., data older than 30 days). Steps: Modify the indexes.conf file, located in $SPLUNK_HOME/etc/system/local/indexes.conf or within an app-specific folder. Example configuration for size- or time-based retention: [your_index]
maxTotalDataSizeMB = 5000 # Set the maximum size of the index in MB
frozenTimePeriodInSecs = 2592000 # 30 days in seconds (30 * 24 * 60 * 60)
maxTotalDataSizeMB: Sets the maximum disk space the index can use. When this limit is reached, older data is deleted. frozenTimePeriodInSecs: Specifies the number of seconds to retain the data. Once the data is older than this, it will be deleted. After the index reaches the size or time threshold, old data is deleted automatically by Splunk.
