ParseSeverity

Overview

The ParseSeverity converter maps custom severity strings to standard OpenTelemetry severity levels. It takes a target value and a severity mapping that defines how custom strings translate to standard levels: fatal, error, warn, info, and debug.

Syntax

ParseSeverity(target, severityMapping)

• target: the string value to parse as a severity level
• severityMapping: a map that defines the mapping from standard OTel severity levels to arrays of match rules

The severity mapping uses this structure:

{
  "fatal": [{"equals": ["CRITICAL", "FATAL"]}],
  "error": [{"equals": ["ERROR", "ERR"]}],
  "warn":  [{"equals": ["WARNING", "WARN"]}],
  "info":  [{"equals": ["INFO"]}],
  "debug": [{"equals": ["DEBUG", "DBG"]}]
}

Each level maps to an array of matchers. The equals matcher checks for exact case-sensitive string matches.

Examples

Input

{
	"_type": "log",
	"body": {
		"level_critical": "CRITICAL",
		"level_warning": "WARNING",
		"level_info": "INFO",
		"level_debug": "DEBUG"
	},
	"resource": {...},
	"attributes": {}
}

Statement

set(attributes["parsed_crit"], ParseSeverity(body["level_critical"], {"fatal": [{"equals": ["CRITICAL", "FATAL", "CRIT"]}], "error": [{"equals": ["ERROR", "ERR"]}], "warn": [{"equals": ["WARNING", "WARN"]}], "info": [{"equals": ["INFO", "INFORMATION"]}], "debug": [{"equals": ["DEBUG", "DBG"]}]}))
set(attributes["parsed_warn"], ParseSeverity(body["level_warning"], {"fatal": [{"equals": ["CRITICAL", "FATAL", "CRIT"]}], "error": [{"equals": ["ERROR", "ERR"]}], "warn": [{"equals": ["WARNING", "WARN"]}], "info": [{"equals": ["INFO", "INFORMATION"]}], "debug": [{"equals": ["DEBUG", "DBG"]}]}))
set(attributes["parsed_info"], ParseSeverity(body["level_info"], {"fatal": [{"equals": ["CRITICAL", "FATAL", "CRIT"]}], "error": [{"equals": ["ERROR", "ERR"]}], "warn": [{"equals": ["WARNING", "WARN"]}], "info": [{"equals": ["INFO", "INFORMATION"]}], "debug": [{"equals": ["DEBUG", "DBG"]}]}))
set(attributes["parsed_debug"], ParseSeverity(body["level_debug"], {"fatal": [{"equals": ["CRITICAL", "FATAL", "CRIT"]}], "error": [{"equals": ["ERROR", "ERR"]}], "warn": [{"equals": ["WARNING", "WARN"]}], "info": [{"equals": ["INFO", "INFORMATION"]}], "debug": [{"equals": ["DEBUG", "DBG"]}]}))

Output

{
	"_type": "log",
	"body": {
		"level_critical": "CRITICAL",
		"level_warning": "WARNING",
		"level_info": "INFO",
		"level_debug": "DEBUG"
	},
	"resource": {...},
	"attributes": {
		"parsed_crit": "fatal",
		"parsed_warn": "warn",
		"parsed_info": "info",
		"parsed_debug": "debug"
	}
}

Each custom severity string was mapped to its corresponding OTel severity level: CRITICAL mapped to fatal, WARNING to warn, INFO to info, and DEBUG to debug.
