How to Investigate a Sudden Loss of Security Log Ingestion

11/10/2026

A gap in centralized logs can result from agent failure, credential expiry, network changes, storage limits, or a source-side configuration update.

Checks to make

Identify affected sources and the last received event, inspect forwarding and collector health, and compare source-local logs with central storage. Preserve local evidence, restore ingestion through a controlled change, and document the gap’s impact.

When to get help
