OS WatcherBlack Box I. OS WatcherBlack Box description

OSWatcher is a toolkit provided by Oracle for operating system monitoring.

OS Watcher Black Box (OSWbb) is a collection of UNIX scripts that are used to collect and archive data and always help locate problems. The OSWbb operation can be set as a background process and then collect data regularly, which calls Unix tools such as vmstat,netstat and iostat.

two。 Supported OS platforms:

AIX

Tru64

Solaris

HP-UX

Linux

III. OS Watcher Black Box installation configuration OSWbb needs to be installed on each node

Upload installation package

Go to the server (put it in a directory with spare space and use df-h to check the directory space)

Extract and install OSwbb

The oswbb folder contains all the required files. The process of unzipping is the process of installing OSWbb. OSWbb does not need to be installed. It can be decompressed directly.

~] # tar-xvf oswbb703.tar-C /

-C: specify the directory to which you are decompressed, and this output is extracted to the root directory

~] # ls / oswbb/-d

/ oswbb/

four。 Uninstall oswbb Uninstall OSWbb, use the rm command to remove the entire folder, as follows:

~] # rm-rf / oswbb/

5. Oswbb use when the OSWbb installation is complete, you can use the start and stop scripts, which create some archived subdirectories the first time OSWbb is used. These archive directories contain multiple subdirectories, one for each subdirectory to collect data. Directories such as: top, vmstat, iostat, mpstat, netstat, ps, etc.

Note that before starting oswbb, you must set the LANG environment variable of OS to English environment, otherwise you will not be able to analyze it during oswbba

~] # export LANG=zh_US

~] View the locale through the output result of date

To start the oswbb startup OSWbb function, use the startOSWbb.sh script in the installation directory. This script has four parameters, as follows:

Parameter 1: frequency interval of data collection, how many seconds are collected

Parameter 2: time for data retention (in hours)

Parameter 3: optional parameter, specify compression method

Parameter 4: optional parameter to specify the location of the archive generated by the collection; default is under the archive directory under oswbba

If no parameters are specified, the default is to collect once in 30 seconds and retain archived data for 48 hours.

In general, we can specify the frequency and retention time, as follows:

~] # cd / oswbb/ # cd to the directory after oswbb is decompressed and installed

] # ls startOSWbb.sh # you can see that there are startoswbb.sh scripts

StartOSWbb.sh

] # nohup. / startOSWbb.sh 5 24 &

# nohup and &: are for running in the background

Parameters are collected once a second at 5:5.

Parameter 24: retain 24 hours of data

] # ps-ef | grep-I osw | grep-v grep# check that oswatcher is running

Root 31930 1 0 19:30 pts/1 00:00:00 / bin/sh. / OSWatcher.sh 5 24

Since parameter 3 and parameter 4 are not specified manually, compression is not used and the archive location is default, that is, under the archive directory under oswbb, as follows

] # pwd

/ oswbb

] # ls archive/

Oswiostat oswmeminfo oswmpstat oswnetstat oswprvtnet oswps oswslabinfo oswtop oswvmstat

Each subdirectory under the archive corresponds to the generated file, such as:

] # ls archive/oswiostat/

Uwaydb_iostat_14.01.03.1900.dat

Uwaydb_iostat_14.01.03.2000.dat

Uwaydb_iostat_14.01.03.2100.dat

Uwaydb_iostat_14.01.03.2200.dat

Uwaydb_iostat_14.01.03.2300.dat

Stop oswbb stop OSWbb, just use the stopOSWbb.sh script. This command will terminate all related processes.

For example

] # ps-ef | grep-I osw | grep-v grep

Root 31930 1 0 19:30 pts/1 00:00:07 / bin/sh. / OSWatcher.sh 5 24

Root 32166 31930 0 19:30 pts/1 00:00:00 / bin/sh. / OSWatcherFM.sh 24 / oswbb/archive

] #. / stopOSWbb.sh

# after the stoposwbb script is executed, the relevant process no longer exists, indicating that it has been stopped

] # ps-ef | grep-I osw | grep-v grep

OS Watcher Black Box Analyzer I. OS Watcher Black Box Analyzer description

We use OSWatcher to collect data and store it in an archive, but these files are not good for analysis, so Oracle provides the OSWbba (OSWatcher Black Box Analyzer) tool, which analyzes the data collected by OSWbb and displays it graphically.

OSWbba does not need to be installed, it is a separate java package

two。 Supported OS platform

AIX

Solaris

HP-UX

Linux

Windows XP

III. Java version restrictions

OSWbba is written in java, so running OSWbba requires at least version 1.4.2 of Java. OSWbba can run on any platform.

Use the following methods to view the java version

] # java-version

Java version "1.6.024"

OpenJDK Runtime Environment (IcedTea6 1.11.1) (rhel-1.45.1.11.1.el6-x86_64)

OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)

If the java version is less than 1.4.2, upgrade java first

four。 Using oswbba involves displaying graphics. You need to install xmanager on the local computer, start the Xmanager-Passive tool, turn off the local firewall, and configure the server host:

] # export DISPLAY=192.168.9.43:0.0

# where 192.168.9.43 is the local ip address

] # xhost + # see the following prompt to prove that the drawing is available

Access control disabled, clients can connect from any host

Enable oswbba

] # java-jar oswbba.jar-I / oswbb/archive

#-I specify the archive directory of the sampled data

Starting OSWbba V7.0
