面试题与答案

Splunk forwarders are used to forward data from various sources to the Splunk indexer. They collect and forward machine data to be indexed and searched.

Example:

A Splunk forwarder installed on a web server can forward access logs to the Splunk indexer for analysis.

Sourcetype is a metadata attribute in Splunk that defines the format of the data. It helps Splunk understand how to index and extract fields from the incoming data.

Example:

If you have log data from a firewall, you might set the sourcetype to 'firewall_logs' to ensure proper indexing and field extraction.

To create a time chart in Splunk, you can use the 'timechart' command in the search query. It visualizes data over time and is often used for trend analysis.

Example:

 | timechart count by sourcetype

Splunk Universal Forwarder is a lightweight version of Splunk that only forwards data without performing indexing. It is used to collect and forward data from various sources to the Splunk indexer.

Example:

Installing Splunk Universal Forwarder on endpoints to forward application logs to the central Splunk indexer for analysis.
