       lwatch.conf   — configuration file for lwatch(1), syntax highlighting for syslog/syslog-ng


       Default configuration file for lwatch is /etc/lwatch/lwatch.conf (built-in value), but you
       can specify another file with -C command line option. Read lwatch(1) for details.

       Everything from # (hash) to end of line is a comment.

   General options
       cfg_ver  - this is obligatory variable and it must be placed as the first option in config
       file. This  variable  contains  version  of  configuration  file  syntax.  Current  manual
       describes version 1.

       rule_action  -  after  successful  matching  rule  lwatch tries to match next one. You can
       choose to exit after executing matching rule changing this parameter from continue (that's
       the  default)  to  exit. You can override this global parameter for each rule. See section
       Actions and modificators.

       use_syslog - if set to yes some messages will be logged through syslog, default is yes

       log_level - how verbose log messages should produce lwatch

       date_color - default color of date part

       host_color - default color of hostname part

       serv_color - default color of service part

       mesg_color - default color of message part

       input_file   -   where   lwatch   is   reading   data   from,    built-in    default    is
       /var/lib/lwatch/syslog.fifo, could be overwritten with command line option -i

       output_file  -  where lwatch output colored data; built-in default is stdout (-), could be
       overwritten with command line option -o

       show_unparsed - by default lwatch ignores lines which cannot be  split  into  date,  host,
       service  and message, set this variable to yes if you would like to see those lines; it is
       the same as command line option -s

   Available colors
       To specify color you can use following strings: black, red, green, brown,  blue,  magenta,
       cyan, lightgray, darkgray, brightred, brightgreen, yellow, brightblue, purple, brightcyan,

   Available log levels
       To specify the  lower  visible  log  level  you  can  use  following  strings:  LOG_EMERG,
       lwatch logs some debug data at LOG_DEBUG, some maybe useful  messages  at  LOG_NOTICE  and
       errors at LOG_ERROR. So, technically, meaningful values are:

          ·  LOG_DEBUG - log everything

          ·  LOG_NOTICE - log maybe useful messages and errors (this is the default)

          ·  LOG_ERROR  -  log only errors (if LOG_NOTICE is too verbose for you this is the next
             recommended setting)

          ·  LOG_CRIT - be quiet

       Please keep in mind that meaningful values may be a subject of change in future releases.

   Matching patterns
       There The True Power of Lwatch is hidden. You can match input  lines  against  PCRE  (Perl
       Compatible  Regular  Expression)  and change output depends on matching. You can read more
       about PCRE in pcrepattern(3) (from libpcre) or in perlre(1) (from perl).

       There are two ways to define matching pattern/action. First one is the  simple  one.  Just
       pattern and one action:

       /regexp/      action

       The  second  one  is  more  complex,  but  it  allows  to  specify more than one action or
       modificator with one pattern:

       /regexp/      {

       There is one important thing you should remember. There is no need to quote /  (slash)  if
       you use it inside regexp pattern. For example:

       //USR/SBIN/CRON/        {       # cron's messages are not important
               color=blue              # display it in blue

   Actions and modificators
       date_color - set date color

       mesg_color, color - set message color

       serv_color - set service name color

       host_color - set hostname color

       ignore - ignore this pattern, do not match next patterns

       exit - do not match next patterns when rule_action is set to continue, in other case it is

       continue - continue with next pattern when rule_action is set to exit, in other case it is
       superfluous; please note, that if ignore> is used in the same action it takes a priority -
       it makes no sense to match other rules for string that has been ignored

       highlight - highlight matched string with given color (see NOTES)

       match_host - match hostname insted message

       match_service - match service name instead message


       highlight action changes the matched text.  That's why the following part of configuration
       wont work:

       /root/                         highlight=brown
       /session closed for user root/ ignore


       (pam_unix) session closed for user root

       would appear as an input line.

       First rule changes the text to:

       (pam_unix) session closed for user [BROWN]root[NORMAL]

       where  [BROWN] and [NORMAL] are control sequences to change color to brown, then change it
       back to default color of this part. Of course this line does not match the second rule and
       you can see it on the output.

       There are two possible workarounds:

          ·  put the ignore pattern before the highlight one

          ·  enhance your second rules like:

       /session closed for user .*root.*/ ignore


       Just look into provided lwatch.conf.
