# MPN health status rule reference

# MPN health status rule reference {#ariaid-title1}

Release version: Brazil  
Updated September 10, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Default rule set (version 0.0.11) for calculating health status for MPN radio and core server components, including error codes.

## Rule structure {#mpn-rag-status-rule-reference__section_rule_structure}

Rules are organized by component type. Health status uses a RAG (Red, Amber, Green) indicator system. For radio and core server components, each condition is a simple field-and-value
match tied to an error code. A green result requires all conditions in the component's green rule to match simultaneously. If no rule matches, the status is unknown.{#mpn-rag-status-rule-reference__mpn-rag-status-rule-reference-para-1}
