OS Watcher (OSW) is a collection of shell scripts intended to collect and archive operating
system and network metrics to aid support of generic performance issues. OSW operates as a
set of background processes on the server and gathers OS data on a regular basis, invoking
such utilities as vmstat, netstat and iostat.
Note: For more details, refer to the OS Watcher user’s guide in MetaLink note 301137.1.
The MetaLink note contains the link for downloading OS Watcher.

2：Configuring OSW
OSWatcher can be configured by editing the CONFIGURATION section of the OSWatcher.sh
script.
Here, the commands, along with their arguments, are listed. You can edit these here to
cause the behavior and output of the commands to change. The default setting for the Linux
platform is shown in the slide.
For example, the output from iostat with the ?x option, as shown above, shows the statistics
of the hard drive but not the partitions. You could change the ?x option to ?p /dev/hda and
the
output would show the individual partitions.

3：Running OSW
要运行 OSW，使用?本 startOSW.sh。
This is the script that starts the OSWatcher program. It accepts 2
arguments which control the frequency that data is collected and the
number of hours worth of data to archive.
$1 = ??的???隔(s)
$2 = 存???的保留??(hours)
缺省情?下，OSW??以 30s????隔，存?48 小?的??.

停止 OSW，使用?本 stopOSW.sh.

5：Viewing OSW Output
The only directory immediately under the osw installation directory is called archive.
That is where all output is stored. In that directory is a subdirectory for each command
that is being repeatedly run during the session. The subdirectory names are made up by
prepending the string “osw” to the command name. They are:
oswiostat
oswmeminfo
oswmpstat
oswnetstat
oswprvtnet
oswps
oswslabinfo
oswtop
Oswvmstat
Under each of those directories are the files that contain the collected data.
The names of those files follow this pattern for organizational purposes:
hostname_command_timestamp.dat
[oracle@Channel-MQ3 osw]$ cd archive
[oracle@Channel-MQ3 archive]$ ls -l

OSWg is a graphing utility which comes shipped with OSW v2.0.0 and
higher. This utility is a stand-alone java program which requires java
1.4.2 or higher. OSWg graphs vmstat data for all unix platforms and
graphs iostat data for solaris and linux only.
