You monitor critical Windows server logs via Bindplane and want immediate notification when no logs are ingested for over 30 minutes. Most efficient notification solution?

• A. New YARA-L rule in SIEM to detect absence of logs.
• B. Windows server sending email on Bindplane error.
• C. Cloud Monitoring alert policy with a metric-absence condition based on server/hostname.
• D. Bindplane heartbeat signal to SecOps every 15 minutes and alert if two missed.

Answer: (C)

Monitoring data gaps directly is the most reliable way to catch when log ingestion stops. The idea is to set up an alert that watches a metric representing how many logs are ingested from each Windows server and triggers when no data points arrive for 30 minutes. This absence-based alert immediately notifies SecOps as soon as the ingestion path goes quiet, and it’s scoped to each host, so you only alert on the affected systems.

This approach leverages built-in alerting features that are designed for exactly this scenario: detecting gaps in data rather than waiting for a specific event. It also scales cleanly—add more servers and you simply get per-host absence alerts, routed through your normal notification channels.

Why the other options aren’t as effective: trying to detect absence with a SIEM rule or a YARA-L rule is brittle and complex, because SIEMs are built around processing events, not detecting the lack of events. Relying on an email notification from a Bindplane error only covers explicit errors and doesn’t address quiet periods where no logs are ingested. A heartbeat-based alert on Bindplane only tells you whether the service is reachable, not whether it’s actually delivering logs, so it can miss real ingestion failures or be misled by heartbeat issues.
