Elasticsearch resource guidelines
editFollow these guidelines to ensure clusters have adequate memory to handle data volume:
- With 2GB of Java Virtual Machine (JVM) heap memory, the risk scoring engine can safely process around 44 million documents, or 30 days of risk data with an ingest rate of 1000 documents per minute.
- With 1GB of JVM heap, the risk scoring engine can safely process around 20 million documents, or 30 days of risk data with an ingest rate of around 450 documents per minute.
Known limitations
editThe risk scoring engine uses an internal user role to score all hosts and users, and doesn’t respect privileges applied to custom users or roles. After you turn on the risk scoring engine for a Kibana space, all alerts in the space will contribute to host and user risk scores.
Asset criticality

editTo use asset criticality, you need the following privileges for the .asset-criticality.asset-criticality-<space-id> index:
| Action | Index privilege |
