NAME

metalog - an alternative syslog daemon

SYNTAX

metalog [options]

DESCRIPTION

Metalog is a modern replacement for syslogd and klogd. The logged messages can be dispatched according to their facility, urgency, program name and/or Perl-compatible regular expressions. Log files can be automatically rotated when they exceed a certain size or age. External shell scripts (ex: mail) can be launched when specific patterns are found.

Metalog is easier to configure than syslogd and syslog-ng, accepts unlimited number of rules and has (switchable) memory bufferisation for maximal performance.

OPTIONS

-a, --async: Improve performance by using buffers (bug log files won't get updated in real time). Can be overridden for individual logs.
-B, --daemonize: Have the server start in background (daemonization).
-c, --consolelevel=0..7: Set the console log level (Linux only).
-C, --configfile=file: Use an alternate configuration file.
-h, --help: Output help information and exit.
-N, --no-kernel: Do not attempt to log messages from the kernel.
-P, --pidfile=file: Use an alternate file to store the process number.
-s, --sync, --synchronous: Start in synchronous mode, with no bufferization. Can be overridden for individual logs.
-v, --verbose: Run in verbose mode (useful for debugging behavior).
-V, --version: Display metalog version information.

SIGNALS

SIGUSR1: Enable synchronous mode.
SIGUSR2: Disable synchronous mode.

FILES
