Saving Raw Data

Gathered /raw data for  1998-2003 is 1998-01 - 2007-07 is saved in 

Code Block
/nfs/slac/g/net/pinger/pingerdata/hep/data

...

/<YYYY>/<host>/
e.g.
/nfs/slac/g/net/pinger/pingerdata/hep/data/2007/brunsvigia.tenet.ac.za/
With files of the form:
-rw-rw-r-- 1 pinger   iepm 584920 Jan  2  2007 ping-2007-01-01.txt.gz

Gathered data from 2004 2007-07 onwards  is saved in:

Code Block
/nfs/slac/g/net/pinger/pingerdata/hep/data/<host>/ping-<YYYY>-<MM>-<DD>.txt.gz
e.g.
/nfs/slac/g/net/pinger/pingerdata/hep/data/pinger.slac.stanford.edu/ping-2011-03-22.txt.gz
/nfs/slac/g/net/pinger/pingerdata/hep/data/pcgiga.cern.ch/ping-2006-09-28.txt.gz


There is also data in the space below but I am unsure of its provenance
Code Block
/nfs/slac/g/net/pinger/pingerdata/hep/data.unite/<host>/ping-<YYYY>-<MM>-<DD>.txt.gz
with files of the form:

There is a script pinger-tar.pl. To save the raw data use the command /afs/slac/package/pinger/pinger-tar.pl. You can get help on this script by going to http://www-iepm.slac.stanford.edu/pinger/scripttable.html and choosing pinger-tar.pl from the pull down list. It lists the directory to find all hosts with data. For each of these hosts it copies all files with names starting ping-* into the anonymous ftp space, then it un-compresses it and tars and compresses it into the FTP space. Partial output from running the script is seen below.

This saves about 200 tar files in ftp://ftp.slac.stanford.edu/users/cottrell. They are for data from 2007-07 forwards. They appear as directories with the directory name being the name of the PingER monitoring agent (MA) host.  For example

The files are tar files and compressed. Together they occupy about 70GBytes compressed or about 300GBytes uncompressed.

Information on each host MA can be found by going to http://www-iepm.slac.stanford.edu/pinger/pingerworld/all-nodes.cf which can be require'd in a perl script, or for currently working MAs http://www-iepm.slac.stanford.edu/pinger/pingerworld/slaconly-nodes.cf  or in the XML file http://www-iepm.slac.stanford.edu/pinger/pingerworld/rss.xml .
