# MPN health status rule reference

Default rule set \(version 0.0.11\) for calculating health status for MPN radio and core server components, including error codes.

## 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.

## Default rules for radio components

|Health status|Field|Value|Error code|
|-------------|-----|-----|----------|
|Red|`alarm_status`|MAJOR|EC2002|
|Red|`alarm_status`|CRITICAL|EC2003|
|Red|`operational_status`|DISABLED|EC2004|
|Red|`operational_status`|NOT\_AVAILABLE|EC2001|
|Red|`cell_status`|INACTIVE|EC2005|
|Red|`cell_status`|NOT\_AVAILABLE|EC2006|
|Red|`mme_status`|DISCONNECTED|EC2001|
|Red|`mme_status`|NOT\_AVAILABLE|EC2001|
|Red|`ap_connection_status`|DISCONNECTED|EC2001|
|Red|`ap_connection_status`|NOT\_AVAILABLE|EC2001|
|Amber|`alarm_status`|MINOR|EC2101|
|Amber|`alarm_status`|INDETERMINATE|EC2102|
|Amber|`alarm_status`|WARNING|EC2103|
|Amber|`operational_status`|UNKNOWN|EC2104|
|Amber|`cell_status`|UNKNOWN|EC2105|
|Amber|`cell_status`|PARTIALLY\_ACTIVE|EC2106|
|Amber|`mme_status`|UNKNOWN|EC2107|
|Amber|`ap_connection_status`|UNKNOWN|EC2107|
|Green|`alarm_status AND operational_status AND cell_status`|NORMAL, ENABLED, ACTIVE \(all three required\)|—|
|Unknown|\(no rule matched\)|—|EC2108|

## Default rules for core server components

|Health status|Field|Value|Error code|
|-------------|-----|-----|----------|
|Red|`edge_connection`|EDGE\_CONN\_STATUS\_UNAVAILABLE|EC3001|
|Red|`edge_connection`|OFFLINE|EC3002|
|Green|`edge_connection`|ONLINE|—|
|Unknown|\(no rule matched\)|—|EC3101|

## Default health rules for network-level aggregation

|Health status|Condition|Error code|
|-------------|---------|----------|
|Red|All radio components are red|EC1001|
|Red|All core server components are red|EC1002|
|Amber|Not all radio components are green|EC1101|
|Amber|Not all core server components are green|EC1102|
|Green|All radio and core server components are green|—|
|Unknown|\(no rule matched\)|EC1103|
