Conduct daily/weekly health checks for data ingestion status, indexing performance, CPU/memory utilization, and storage capacity. Detect and resolve issues related to dropped logs, parsing errors, ingestion failures, and time sync mismatches. Log Source Onboarding & Validation Validate newly onboarded log sources for correct parsing, categorization, and normalization. Maintain an up-to-date log source inventory and ingestion dashboard. Verify logs are received in the correct format, with relevant fields available for detection and correlation. Data Quality & Integrity Ensure log data integrity by continuously reviewing timestamp accuracy, event duplication, and message completeness. Implement log source heartbeat monitoring or alerting for missing logs or ingestion gaps. Automation & Dashboards Develop or enhance dashboards, scripts, or tools to automate health monitoring and alerting (e.g., using SPL, KQL, Python, PowerShell). Create visualizations and reports to track ingestion KPIs, latency, log volume trends, and data anomalies.
