- Syntax: logmgr logfile logpatt arcpatt -a "arc cmd" [-k n1] [-s n2] [-l]
- [-m] [-v] [-w]
-
- Function: maintains a logfile directory.
-
- Arguments:
-
- logfile
- is the name of the currently existing log file.
-
- logpatt
- specifies a naming pattern for the logfile to be renamed to.
-
- arcpatt
- specifies an archive filename pattern to be used for storing
- old logfiles.
-
- "arc cmd"
- specifies the command and initial arguments for archiving
- old logs. Note that quotes are required if this argument
- contains any spaces.
-
- -k n1
- specifies how many old log to keep. Old logs in
- excess of this count will be deleted. A specification of zero
- (the default) means that no old logs will be deleted. Note:
- this count includes the just-renamed log.
-
- -s n2
- specifies how many old archives to keep. Old ones in
- excess of this count will be deleted. A specification of zero
- means that no old archives will be deleted. The default is 2.
-
- -l
- log all logmgr actions to the newly-created logfile.
-
- -m
- create new archive files monthly (the default).
-
- -v
- log all logmgr actions to the stdout (usually the console
- but can be redirected).
-
- -w
- create new archive files weekly (the default is monthly).
-
-
- Note:
-
- The "/" character may be used in place of "-" for those who prefer
- this style (.e.g /k 2).
-
-
- Warning:
-
- If you change from monthly to weekly archives using the same arcpattern
- you CANNOT change back until the beginning of the next year. The logmgr
- has no way of determining whether, for example, log-1290.arc refers
- to the archive for week 12 or for December except by the frequency
- specified in the command line (either explicitly or implicitly). Changing
- from monthly to weekly causes no problems, except for a gap in the
- numbering of the archives.
-
- Description:
-
- The logmgr command functions as follows:
-
- 1) The current logfile is renamed to a name created from the logpattern
- argument. Currently this is limited to a Julian-date specification,
- e.g. fd-log.###, where the ### is translated to the Julian day number.
- If this file already exists then logmgr has already been run today
- and will exit.
-
- 2) All other (excluding today's) old logs matching the logpattern
- are archived using the "arc cmd" string into an archive file derived
- from the arcpattern command. Currently this is limited to a month/year
- specification, e.g., log-####, where the #### will be translated
- to the MMYY digits of the month and year, for monthly archives (the
- default), or WWYY digits of the week and year for weekly archives
- (specified via the -w option).
-
- 3) All archives (including, potentially, the current one) matching the
- arcpatt(.*) in excess of the specified count will be deleted.
-
- 4) All old logs matching the logpatt in excess of the specified count
- will be deleted.
-
-
- Example:
-
- Today is December 16, 1990, i.e. day 350 of the year. Currently existing
- archive files are log-1189.arc log-1289.arc, log-0190 thru log-1190 (the
- logmgr has not been run recently), together with old log files fd-log.345
- thru fd-log.349.
-
- The command line
-
- logmgr fd.log fd-log.### log-#### -a "arc m" -s 10 -l -v
-
- results in the following actions:
-
- 1) fd.log is renamed fd-log.350
-
- 2) the command line
- arc m log-1290 fd-log.345 fd-log.346 fd-log.347 fd-log.348 fd-log.349
- is executed
-
- 3) the old archive files log-1189.arc, log-1289.arc, log-0190.arc and
- log-0290.arc are deleted, leaving 10 archive files (log-0390.arc
- thru log-1290.arc).
-
- 4) all these actions are reported in a newly-created fd.log.
-
- 5) all these actions are reported on stdout.
-
- Limitations:
-
- Currently only the Julian date pattern for old logs and the month/year or
- week/year patterns for log archives are supported.
-
- Because the extension of the log archive is dependent on the particular
- archiving command, arcpatt.* is used to match which files to consider
- eligible for deletion. The existence of additional files matching this
- pattern (e.g. in the above example log-1289.bak) will cause potential
- problems.
-
- The algorithm used to decide which log archives to delete is based solely
- upon a sort of the log archive file names. This is done in order to avoid
- the potential problems resulting from manual updating of the files if a
- date/time modified sort were used.
-
-
- Implementation:
-
- This program was written in C++ and compiled using Borland C++ version 2.
-
- Note:
-
- The logmgr will swap itself out to whichever is available of extended or
- expanded memory or a temporary disk file while executing the archival
- command.
