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.
GridFTP Installation Instruction
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://acs.lbl.gov/NetLogger-releases/doc/trunk/manual.html#python_install
The python install section current as of Jan 26 2010, is included here for quick reference.
Install Python
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
tar xzvf netlogger-python-VERSION.tar.gz
cd netlogger-python-VERSION
- Run Python's standard install sequence
python setup.py build
python setup.py install
Alternately, to install under "$NETLOGGER_HOME"
export NETLOGGER_HOME=/my/path # or use setenv on csh
python setup.py install --home=$NETLOGGER_HOME
export PYTHONPATH=$NETLOGGER_HOME/lib/python
export PATH=$PATH:$NETLOGGER_HOME/bin
Patching NetLogger to hadle 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).
Download the Source Code as a tar ball
- tar -xvf FileTransfer_MA.1b.tar
- mkdir /var/log/perfsonar
- Run the SQL Procedure(mysql) on the netlogger database to produce a secondary database. This secondary database is the one, the FTMA service will be interacting with.
From the svn
- Checkout the latest version of FTMA:
- With username and password:
*svn checkout https://svn.internet2.edu/svn/perfSONAR-PS/branches/FileTransfer/*
OR - Anonymously:
*svn checkout https://anonsvn.internet2.edu/svn/perfSONAR-PS/branches/FileTransfer/*
- With username and password:
Configuration
- mkdir /var/log/perfsonar(Create the log directory as is shown by daemon_logger.conf)
- Run the SQL Procedure(mysql) on the netlogger database to produce a secondary database. This secondary database is the one, the FTMA service will be interacting with.

Installation:
...
How to run the Service:
- cd bin
- sh FtpMaExecute.sh --skip-input || --help
...
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:
- sh FtpMaExecute.sh --skip-input || --help
o Attempts to install the missing, perl modules.
o Stops any previous running instance of the service.
o Creates a backup of any existing log file.
o 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
o Starts a new Instance of the service by running daemon.pl
Client Application:
The service includes a basic client tool as well.
- perl FTP_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.
- perl FTP_client.pl --help
-d Switch to debug level, one of 0,1 or 2
--debug Same as -d
--url Url to the MA Service(FT)
default is localhost
--data Output Data as well
--src source ip (string)
--dst destination ip (string)
--SrcPath metadata param: Source file path(string)
--DestPath metadata param: Destination file path(string)
--stripes metadata param: number of stripes
--buffer metadata param: bufer size
--block metadata param: block size
--streams metadata param: number of streams
--program metadata param: program used for file transfer
--user metadata param: user, who requested the file transfer
--initEpochTime initial Time limit in Epoch (integer)
--finalEpochTime Final Time limit in Epoch (integer)
--initUtcTime initial Time limit in UTC (string)
--finalUtcTime final Time limit in UTC (string)
--startTuple start point of results to return
--tupleLimit number of tuples to return
-h Print this help
--help Same as -h
- perl FTP_client.pl -d --data --DestPath=/ --stripes=1 --src=192.168.117.128 --dst=131.225.107.12 --initEpochTime=1220000000 --finalEpochTime=1225408002
*
o This execution will fetch metadata where destination path, stripes, source ip address and destination ip address is defined by the parameters passed.
o The --data argument makes sure that the returned metadata is then used to fetch data with start time and end time within the given limitation.
o The -d argument provides the debug data as well.
- FT_client.pl -d 2 --data --stripes=1 --user=dang --startTuple=400 --tupleLimit=20
