36 The Net::DNS::SEC::Tools::rolllog module provides logging interfaces
37 for the rollover programs. The logging interfaces allow log messages
38 to be recorded. rollerd must be running, as it is responsible for
39 updating the log file.
40 Each log message is assigned a particular logging level. The valid
42 logging levels are:
43 text numeric meaning
45 ---- ------- -------
46 tmi 1 The highest level -- all log messages
47 are saved.
48 expire 3 A verbose countdown of zone expiration
49 is given.
50 info 4 Many informational messages are recorded.
51 phase 6 Each zone's current rollover phase
52 is given.
53 err 8 Errors are recorded.
54 fatal 9 Fatal errors are saved.
55 The levels include all numerically higher levels. For example, if the
57 log level is set to phase, then err and fatal messages will also be
58 recorded.

61 rolllog_file(newfile,useflag)
62 This routine sets and retrieves the log file for rollerd. The
63 newfile argument specifies the new log file to be set. If newfile
64 exists, it must be a regular file.
65 The useflag argument is a boolean that indicates whether or not to
67 give a descriptive message if an invalid log file is given. If
68 useflag is true, the message is given and the process exits; if
69 false, no message is given. For any error condition, an empty
70 string is returned.
71 rolllog_gettz()
73 This routine returns the timezone selector currently in use. This
74 value may be either 'gmt' (for Greenwich Mean Time) or 'local' (for
75 the host's local time.)
76 rolllog_level(newlevel,useflag)
78 This routine sets and retrieves the logging level for rollerd. The
79 newlevel argument specifies the new logging level to be set.
80 newlevel may be given in either text or numeric form.
81 The useflag argument is a boolean that indicates whether or not to
83 give a descriptive message and exit if an invalid logging level is
84 given. If useflag is true, the message is given and the process
85 exits; if false, -1 is returned.
86 If given with no arguments, the current logging level is returned.
88 In fact, the current level is always returned unless an error is
89 found. -1 is returned on error.
90 rolllog_levels()
92 This routine returns an array holding the text forms of the user-
93 settable logging levels. The levels are returned in order, from
94 most verbose to least.
95 rolllog_log(level,group,message)
97 The rolllog_log() interface writes a message to the log file. Log
98 messages have this format:
99 timestamp: group: message
101 The level argument is the message's logging level. It will only be
103 written to the log file if the current log level is numerically
104 equal to or less than level.
105 group allows messages to be associated together. It is currently
107 used by rollerd to group messages by the zone to which the message
108 applies.
109 The message argument is the log message itself. Trailing newlines
111 are removed.
112 rolllog_num(loglevel)
114 This routine translates a text log level (given in loglevel) into
115 the associated numeric log level. The numeric log level is
116 returned to the caller.
117 If loglevel is an invalid log level, -1 is returned.
119 rolllog_settz(tzsel)
121 This routine sets the timezone to be used for timestamps in
122 messages written to the log. This tzsel value may be either 'gmt'
123 (Greenwich Mean Time) or 'local' (for the host's local time.)
124 tzsel may be uppercase or lowercase; the value will be converted to
125 lowercase. If no value is passed, then the default will be used.
126 The current timezone selector is returned. If an invalid selector
128 is given, then an undefined value is returned.
129 rolllog_str(loglevel)
131 This routine translates a log level (given in loglevel) into the
132 associated text log level. The text log level is returned to the
133 caller.
134 If loglevel is a text string, it is checked to ensure it is a valid
136 log level. Case is irrelevant when checking loglevel.
137 If loglevel is numeric, it is must be in the valid range of log
139 levels. undef is returned if loglevel is invalid.
140 rolllog_validlevel(level)
142 This interface returns a boolean value indicating if the given
143 logging level is valid.
144 The level argument is the logging level to be validated. It may be
146 a numeric or textual value.
