Level : int
in package

Represents the log levels

Monolog supports the logging levels described by RFC 5424 https://datatracker.ietf.org/doc/html/rfc5424 but due to BC the severity values used internally are not 0-7.

To get the level name/value out of a Level there are several options:

  • Use ->getName() to get the standard Monolog name which is full uppercased (e.g. "DEBUG")
  • Use ->toPsrLogLevel() to get the standard PSR-3 name which is full lowercased (e.g. "debug")
  • Use ->toRFC5424Level() to get the standard RFC 5424 value (e.g. 7 for debug, 0 for emergency)
  • Use ->name to get the enum case's name which is capitalized (e.g. "Debug")

To get the internal value for filtering, if the includes/isLowerThan/isHigherThan methods are not enough, you can use ->value to get the enum case's integer value.

Methods

fromName()  : static

Cases

Debug

Detailed debug information

Info

Interesting events

Examples: User logs in, SQL logs.

Warning

Exceptional occurrences that are not errors

Examples: Use of deprecated APIs, poor use of an API, undesirable things that are not necessarily wrong.

Critical

Critical conditions

Example: Application component unavailable, unexpected exception.

Alert

Action must be taken immediately

Example: Entire website down, database unavailable, etc. This should trigger the SMS alerts and wake you up.
