Introduction +2. Usage +3. Files +4. Configuration Format +5. How to use + +1. Introduction +=============== +Systemtap initscript aims to provide +- running systemtap script as a service with dependency. +- easy way to control(start/stop) those scripts individually. +The dependency means that which user-defined systemtap script is required by +other script (Here the scripts don't include tapsets). This dependency +will be useful for users who use -DRELAY_HOST and -DRELAY_GUEST. + +2. Usage +======== +2.1 Synopsis + +/sbin/service systemtap {start|stop|restart|status|compile|cleanup} \ + [-r kernelrelease] [-c config] [-R] [-y] [script(s)] + +2.2 Commands + You have to specify one of the below commands. + +2.2.1 start + Run script(s). If the script(s) is already started, the command will be + ignored. If it fails to start, return FAIL. If AUTOCOMPILE option is 'yes' + (see 4.1.9), this will try to compile or update the specified script when + one of the below condition is true. + - compiled cache file does not exist. + - mtime (modified time stamp) of original script file is newer than compiled + script cache. + - script options which is used when compiling(see 4.2.1) has been changed. + - result of `uname -a` has been changed. + If no scripts specified from command line, it starts all scripts in the script + directory or the scripts specified by DEFAULT_START in config (see 4.1.10). + +2.2.2 stop + Stop script(s). If the script(s) is already stopped, this will be ignored. + If it fails to stop, return FAIL. + If no scripts specified from command line, it stops all running scripts. + +2.2.3 restart + Stop and start script(s) again. + +2.2.4 status + Show running script(s) status and dependency. + +2.2.5 compile + Compile script(s) on the specified kernel. This command takes '-r' option + which specifies the release of the kernel(see 2.3.4) on which you would + like to compile script(s). This command asks user whether it can overwrite +existing caches. + +2.2.6 cleanup + Cleanup compiled script(s) from cache directory(see 3.4). This command also + takes '-r' option. If '-r' option is omitted, cleanup all caches for running + kernel. This command asks user whether it can remove caches. + +2.3 Options + Systemtap initscript can have some options. However, since user can't pass + these options on boot, these options are only for testing or managing scripts + after booting. + +2.3.1 -c config_path + You can specify configuration path of this initscript. + +2.3.2 script(s) + You can specify individual scripts to the commands. If you omit to specify + any script, systemtap initscript will execute the command with all scripts + in the script directory(except 'start' and 'stop' command, see 2.2.1 and + 2.2.2). + +2.3.3 -R + If this option is specified, systemtap initscript will try to solve + dependency of specified script(s). This option is always set if you don't + specify any script(s) from command line. + +2.3.4 -r kernelrelease + You can specify release version of the kernel(e.g. 2.6.26.1).
