NAME

iotrace_syphon - read iotrace log and dump to a file

SYNOPSIS

iotrace_syphon [OPTIONS...]

DESCRIPTION

iotrace_syphon is essentially a glorified cat. It reads data from /dev/iotrace (by default) every 30 seconds and copies the contents to /var/log/iotrace/DATE, where DATE is a filename composed of current year-month-date-hour. All error messages are sent to syslog.

It accepts the following command-line options.

-f, --file=TRACEDEV: Set the iotrace device name. Default name is /dev/iotrace. iotrace_syphon automatically creates the device (via mknod(2)) if the specified iotrace device does not yet exist.
-d, --daemon: Run the program as a daemon.
-i, --interval=N: Read contents from /dev/iotrace every N seconds. N defaults to 30.
-o, --output=DIR: Set the base output directory. The directory defaults to "/var/log/iotrace".
