@@ -202,8 +202,12 @@ Graylog under `System -> Configurations -> MCP` and use stream IDs internally;
the fgAI stream picker resolves titles in the UI.
For live monitoring, `graylog_range_seconds` controls how far back each MCP poll
searches. The default is one hour, which keeps findings and correlations more
stable than a very short window while still limiting MCP query cost.
searches. The default is 300 seconds, so each poll re-checks the last five
minutes. `graylog_max_events_per_stream` caps raw events fetched from each
stream during that window. If a stream hits the cap, the dashboard marks the
window as truncated because high EPS means SignalScope sampled only part of the
Graylog result set. For very high-volume streams, prefer aggregate baselines and
targeted drill-down queries over trying to pull every raw event through MCP.
