Log content transformation (Logs Classic)

Log Monitoring Classic

Dynatrace enables you to transform logs ingested both via OneAgent and API.

Transform the API-ingested logs

Generic log ingestion automatically transforms status, severity, level, and syslog.severity severity keys to the loglevel attribute.

The input values for the status, severity, level, and syslog.severity severity keys are transformed (transformation is not case sensitive) into output values for the loglevel attribute based on the mapping below:

Input value

Output value

Example value

Begins with emerg or f

EMERGENCY

Emergency, fail, Failure

Begins with e excluding emerg

ERROR

Error, error

Begins with a

ALERT

alarm, Alert

Begins with c

CRITICAL

Critical, crucial

Begins with s

SEVERE

Severe, serious

Begins with w

WARN

warn, Warning

Begins with n

NOTICE

note, Notice

Begins with i

INFO

Info, information

Begins with d or trace or verbose

DEBUG

debug, TRACE, Verbose

Transform all types of logs

This transformation applies both to OneAgent-ingested logs and API-ingested logs.

Additionally, for each log event, a status attribute is created with a value that is a sum of loglevel values based on the following grouping:

Included loglevel values

Combined status attribute value

SEVERE, ERROR, CRITICAL, ALERT, FATAL, EMERGENCY

ERROR

WARN

WARN

INFO, TRACE, DEBUG, NOTICE

INFO

NONE

NONE

For example: The level severity key in the generic log ingestion API request parameter contains the value serious.

  1. The level severity key is transformed into the loglevel attribute with the serious value mapped to SEVERE based on the above table.
  2. The loglevel attribute containing the SEVERE value is grouped into status attribute. Based on the grouping table above, the status attribute will contain the ERROR value.
  3. For the log event details, the log viewer will report the following:
  • status - ERROR
  • loglevel - SEVERE

Attributes added during a log ingest via OneAgent

During the log ingestion via OneAgent, the following attributes are added automatically:
