Different Log levels

AntonioSousa — Thu, 14 Nov 2024 01:55:26 GMT

Log levels are no easy thing. Dynatrace even has a page where it documents how different types of log severity keys are transformed into the loglevel attribute: https://docs.dynatrace.com/docs/observe-and-explore/log-monitoring/acquire-log-data/lm-log-data-transformation

Dynatrace uses the following values for loglevel:

EMERGENCY ERROR ALERT CRITICAL SEVERE WARN NOTICE INFO DEBUG

Now, these are different from RFC 3164, which was superseded by RFC 5424, and are known as the BSD syslog Protocol:

0 Emergency: system is unusable 1 Alert: action must be taken immediately 2 Critical: critical conditions 3 Error: error conditions 4 Warning: warning conditions 5 Notice: normal but significant condition 6 Informational: informational messages 7 Debug: debug-level messages

Java has yet other levels (in https://docs.oracle.com/javase/8/docs/api/java/util/logging/Level.html😞

SEVERE (highest value) WARNING INFO CONFIG FINE FINER FINEST (lowest value)

And of course Windows would be different (in https://learn.microsoft.com/en-us/answers/questions/788082/where-are-event-log-levels-defined-and-how-can-i-c )

0 Log Always 1 Only critical errors 2 All errors, includes win:Critical 3 All warnings, includes win:Error 4 All informational content, including win:Warning 5 All tracing, including previous levels

I have also converted from Cisco definitions, as described here: https://community.dynatrace.com/t5/Dynatrace-tips/Using-CASE-in-DPL/td-p/262365

But I believe there are many more. If you know of any page/documentation, or other log levels, please comment them below.
