NAME

6       Log::Agent::Priorities - conversion between syslog priorities and
7       levels
8

SYNOPSIS

10        Not intended to be used directly
11

DESCRIPTION

13       This package contains routines to convert between syslog priorities and
14       logging levels: level_from_prio("crit") yields 2, and
15       prio_from_level(4) yields "warning", as does prio_from_level(5).
16
17       Here are the known priorities (which may be abbreviated to the first 2
18       letters, in a case-insensitive manner) and their corresponding logging
19       level:
20
21             Name    Level   Traditional    Export
22           --------- -----  --------------  ------
23           none       -1                    NONE    (special, see text)
24           emergency   0    (emerg, panic)  EMERG
25           alert       1                    ALERT
26           critical    2    (crit)          CRIT
27           error       3    (err)           ERROR
28           warning     4                    WARN
29           notice      6                    NOTICE
30           info        8                    INFO
31           debug       10                   DEBUG
32
33       The values between parenthesis show the traditional syslog priority
34       tokens.  The missing levels (5, 7, 9) are there for possible extension.
35       They currently map to the level immediately below.
36
37       The Export column lists the symbolic constants defined by this package.
38       They can be imported selectively, or alltogether via the ":LEVELS" tag,
39       as in:
40
41           use Log::Agent::Priorities qw(:LEVELS);
42
43       The special token "none" may be used (and spelled out fully) on special
44       occasions: it maps to -1, and is convenient when specifying a logging
45       level, for instance: specifying "none" ensures that no logging will
46       take place, even for emergency situations.
47
48       Anywhere where a priority is expected, one may specify a number taken
49       as a logging level or a string taken as a priority. If the default
50       mapping outlined above is not satisfactory, it can be redefined by
51       specifying, for instance "notice:9". It will be taken as being of level
52       9, but with a "notice" priority nonetheless, not "info" as it would
53       have been implicitely determined otherwise.
54
55       The routine priority_level() decompiles "notice:9" into ("notice", 9),
56       and otherwise uses prio_from_level() or level_from_prio() to compute
57       the missing informatin.  For instance, given "critical",
58       priority_level() routine will return the tuple ("critical", 2).
