Splunk review

Powerful for troubleshooting via deep log correlation.

Verdict

Splunk's strength lies in its market-leading log analytics engine, making it a powerful choice for troubleshooting infrastructure issues when deep log correlation is the primary requirement.

What customers praise

The Splunk Search Processing Language (SPL) allows for incredibly powerful and flexible data querying that is unmatched by most competitors.

What customers criticise

Splunk is notoriously expensive, with costs scaling rapidly with data volume, and its infrastructure monitoring UI is less intuitive than its log search interface.
