Use the included make file and just type: make

make
make clean

Command line argument options

./pretty -h
usage: ./pretty [-hlvz] [ZONEINFO]
   -l       List out program timezone specifiers
   -z       Specify time zone to convert too
   -v       Print version
   -h, -?   Print options

./pretty -l

./pretty -z p

Example usage

Ensure the program is in your search path.

grep -ais "nrt.*BGP_IO_ERROR_CLOSE_SESSION:" syslogngfile.log | pretty -z nrt

tail -f syslogngfile.log | pretty -z nrt

Explanation of options

• ./pretty -h OR ./pretty -?
  • Prints out quick options
• ./pretty -v
  • Prints out author and version
• ./pretty -l
  • Lists out all the programmed in TIMEZONES specifiers that you can use
• ./pretty -z p
  • Convert the piped in syslogng text to PST8PDT timezone

Additional Notes

Syslog-ng string format the piped in text should be (taken from /etc/syslog-ng/conf.d/syslogngfile.conf)

template("${R_ISODATE} ${SOURCEIP} ${HOST} ${PROGRAM}[${PID}]: $MSG\n");

To add additional Zones and/or aliases:

• Edit the string array named zonetable.
  • Lines must end with the trailing NULL
  • Last line needs to be a NULL by it's self.
  • If the number of columns exceeds 15, then increase the defined preprocessor macro named TIMEZONECOLUMNS to match.
• Update the version minor number
