XAS::Docs::Metrics::Installation - how to install the XAS Metrics processor

XAS is middleware for datacenter operations. It provides standardized methods, modules and philosophy for constructing applications typically used to manage a datacenter. This system is based on production level code.


Since the code repository is git based, you can use the following commands:

    # mkdir XAS-Metrics
    # cd XAS-Metrics
    # git init
    # git pull master

Or you can download the code from CPAN in the following manner:

    # cpan -g XAS-Metrics
    # tar -xvf XAS-Metrics-0.01.tar.gz
    # cd XAS-Metrics-0.01

When done, the following commands are run from that directory.


On Unix like systems, using pure Perl, run the following commands:

    # perl Build.PL --installdirs site
    # ./Build
    # ./Build test
    # ./Build install
    # ./Build post_install

If you are DEB based, Debian build files have been provided. If you have a Debian build environment, then you can do the following:

    # debian/rules build
    # debian/rules clean
    # dpkg -i ../libxas-metrics-perl_0.01-1_all.deb

If you are RPM based, a spec file has been included. If you have a rpm build environment, then you can do the following:

    # perl Build.PL
    # ./Build --installdirs vendor
    # ./Build test
    # ./Build dist
    # rpmbuild -ta XAS-Metrics-0.01.tar.gz
    # cd ~/rpmbuild/RPMS/noarch
    # yum --nogpgcheck localinstall perl-XAS-Metrics-0.01-1.noarch.rpm

Each of these installation methods will overlay the local file system and tries to follow Debian standards for file layout and package installation.

On Windows, do the following:

    > perl Build.PL
    > Build
    > Build test
    > Build install
    > Build post_install

It is recommended that you use Strawberry Perl, ActiveState Perl doesn't have all of the necessary modules available.


    Not all of the Perl modules have been included to make the software
    run. You may need to load additional CPAN modules. How you do this,
    is dependent on how you manage your systems. This software requires
    Perl 5.8.8 or higher to operate.


If you are planning to use a database as your datastore. The following will create a SQLite3 database.

On Unix/Linux do the following:

    # xas-create-schema --schema XAS::Model::Database::Metrics --directory .
    # sqlite3 /var/lib/xas/metrics.db < ./XAS-Model-Schema-0.01-SQLite.sql
    # rm -f ./XAS-Model-Schema-0.01-SQLite.sql

On Windows do the following:

    > xas-create-schema --schema XAS::Model::Database::Metrics --directory .
    > sqlite3 \XAS\lib\metrics.db < XAS-Model-Schema-0.01-SQLite.sql
    > delete XAS-Model-Schema-0.01-SQLite.sql


You should check the metric configuration file to see if the proper modules are being loaded.

Once that is done. You need to start the collector. On Debian or RHEL you would issue the following commands:

    # service xas-metrics start
    # chkconfig --add xas-metrics

On Windows, use these commands:

   > xas-metrics --install
   > sc start XAS_METRICS

Now you can check the log files for any errors and proceed from there.


After installing, you can find documentation for this module with the perldoc command.

    perldoc XAS-Metrics
