Key Components of Splunk’s Indexing Process

Splunk’s indexing process consists of multiple stages that ingest, process, and store data efficiently for search and analysis.

✅1. Input Phase (E)

Collects data from sources (e.g., syslogs, cloud services, network devices).

Defines where the data comes from and applies pre-processing rules.

Example:

A firewall log is ingested from a syslog server into Splunk.

✅2. Parsing (A)

Breaks raw data into individual events.

Applies rules for timestamp extraction, line breaking, and event formatting.

Example:

A multiline log file is parsed so that each log entry is a separate event.

✅3. Indexing (C)

Stores parsed data in indexes to enable fast searching.

Assigns metadata like host, source, and sourcetype.

Example:

An index=firewall_logs contains all firewall-related events.

❌Incorrect Answers:

B. Searching → Searching happens after indexing, not during the indexing process.

D. Alerting → Alerting is part of SIEM and detection, not indexing.
