http://confluence.slac.stanford.edu/display/IEPM/FTMA+Design

Source:

• FTMA source tar ball
• SQL Procedures to build Database for FTMA

Pre-Req:

You might need to install the following perl modules if not already installed. Easiest way to do this is to use cpan e.g. "cpan module_name"

Perl:

• Module::Load
• HTTP::Daemon
• XML::SAX
• Config::General
• aliased
• Readonly
• Term::ReadKey
• DBI::DBD
• DBD::mysql
• DBD::SQLite
• Class::Accessor
• Class::Fields
• Params::Validate
• Statistics::Descriptive
• Data::UUID
• IO::Interface
• DateTime
• Error
• Date::Manip (this may require perl upgrade to 5.10 or above, directions)
• Log::Dispatch::FileRotate
• Log::Log4perl

Additionally more components may be required, which may come up when one tries to run the startup script of the service (section "How to run the service"):

• XML::LibXML

Installation:

Theoretically, the service can work with any kind of File Transfer protocol. For test purposes and limiting the large amount of possibilities we use GridFTP as a primary File Transfer Tool.

...

• There are a number of online resources, that can help an administrator, install GridFTP. Some of them are:
  • http://www.globus.org/toolkit/docs/latest-stable/data/gridftp/admin/
• A bug in GridFTP causes intervals to be calculated incorrectly unless you use a very recent version of GridFTP or the subversion trunk version of NetLogger.
• There is generally no restriction on the version of GridFTP to be used, however, it is advised to use the latest one, with minimum security risks.

NetLogger Installation

NetLogger forms the basis of Data collection in this service. A detailed description of installing NetLogger can be found by following this URL:http://acsconfluence.slac.lblstanford.govedu/NetLogger-releasesdisplay/doc/trunk/manual.html#python_install
The python install section current as of Jan 26 2010, is included here for quick reference.

Install Python Version

Prerequisites

The following Python modules may be needed by the NetLogger pipeline to interact with the database. To install these modules, either use a package manager such as Debian's APT, the RedHat/etc. yum, FreeBSD ports, etc., use Python's easy_install command from setuptools or download and install from source. The easy_install command and download URL are given below.

...

MySQLdb for MySQL

...

 easy_install MySQLdb 

web site: http://sourceforge.net/projects/mysql-python

...

psycopg2 or pgdb for PostgreSQL

...

 easy_install psycopg2 

web site: http://www.initd.org/pub/software/psycopg/

Install

Below are instructions for installing the Python instrumentation API and tools.

...

Install from source

...

• Unpack sources

  • Code Block
    tar xzvf netlogger-python-VERSION.tar.gz

  • Code Block
    cd netlogger-python-VERSION

• Run Python's standard install sequence

  Code Block
  python setup.py build python setup.py install

• Alternately, to install under "$NETLOGGER_HOME"

  Code Block
  export NETLOGGER_HOME=/my/path # or use setenv on csh python setup.py install --home=$NETLOGGER_HOME export PYTHONPATH=$NETLOGGER_HOME/lib/python export PATH=$PATH:$NETLOGGER_HOME/bin

Patching NetLogger to handle GridFTP logs(buggy/nob-buggy):

To patch your NetLogger distribution, you could just drop this file into the download directory under python/netlogger/parsers/modules/ , then reinstall (e.g. python setup.py install).

Executing NetLogger

Detailed Instructions on using NetLogger can be found here:http://acs.lbl.gov/NetLogger-releases/doc/trunk/cookbook.html

PerfSONAR_PS FTMA

Download the Source Code as a tar ball

...

• Create the log Directory

  Code Block
  mkdir /var/log/perfsonar (Create the log directory as is shown by daemon_logger.conf)

• Create a mysql database for FTMA service to interact with:

  Code Block
  mysql -u $USER -p $PASS -e "create database ft_ma"

• Run the SQL Procedure(mysql) on the netlogger database to produce a secondary database.

...

Settings for bin/daemon.conf file

Change "db_name", "db_username" and "db_password" in the following file:

How to run the Service:

* cd bin
* sh FtpMaExecute.sh \--skip-input \|\| \--help

• • Attempts to install the missing, perl modules.
  • Stops any previous running instance of the service.
  • Creates a backup of any existing log file.
  • Everytime the script executes, it copies the log file from the main log directory to an hourlyfolder in the same directory. The folder is named as: Ftp_MM-DD-YY:HH
  • Starts a new Instance of the service by running daemon.pl

Client Application:

The service includes a client tool to do some preliminary testing. This tool is present inside the bin dir as well.

How to run the Service:

Before running the service, we must have the database. So far we only created the database and did not copy any tables/contents. To do this we must have a file that performs sql functions of adding and filling tables. The file should be a part of the FTMA package retrieved via svn checkout and should be placed inside "FileTransfer/perfSONAR_PS-FileTransfer/contrib" directory. The file can used in the following manner (you might need to do sudo):

If mysql not started then start it:

/etc/init.d/mysqld start

Load the mysql dump into a database:

mysql -D ft_ma < mysql_backup

Once done do the following to start the service:

* cd contrib
* sh FT_MA_Startup.sh \

    * sh FtpMaExecute.sh --skip-input || \--help

Client Application:

The service includes a basic client tool as wellto do some preliminary testing. This tool is present inside the bin dir.

• Code Block
  perl FTPFT_client.pl

This simple execution will fetch all the metadata from the service, and provide the user with a final output showing all the metadata keys mapped on source and destination ip addresses.
