Format of data etc

See PingER data flow at SLAC

Saving

The most likely data to be of use to others is the analyzed/aggregated data. This is kept in

/nfs/slac/g/net/pinger/pingerreports/hep/

There is a lot of data so you will need a lot of space.  I suggest you use the /tmp ditrectory as intermediate storage, do one metric at a time (e.g. average_rtt), one size (e.g. 100) and one by (e.g. by-node). If this does not work send an email to unix-admin temporary requesting space in /afs/slac/public/users/cottrell (this is accessible from anonymous FTP). Note you will need space for the copied directory and for the tar's and zipped file.  

For 1 metric (average_rtt)

$mkdir /afs/slac/public/users/cottrell/average_rtt-100-by-node

$cp -v /nfs/slac/g/net/pinger/pingerreports/hep/average_rtt/average_rtt-100-by-node* /afs/slac/public/users/cottrell/average_rtt-100-by-node

$tar -cvzf /afs/slac/public/users/cottrell /archive-average_rtt-100-by-node.tar /afs/slac/public/users/cottrell/average_rtt-100-by-node/average_rtt-100-by-node

For all metrics with 100Byte pings by node

 

$mkdir /afs/slac/public/users/cottrell/metrics-100-by-node

 

$cp -v /nfs/slac/g/net/pinger/pingerreports/hep/*/*-100-by-node* /afs/slac/public/users/cottrell/metrics-100-by-node

 

$tar -cvzf /afs/slac/public/users/cottrell /archive-average_rtt-100-by-node.tar /afs/slac/public/users/cottrell/average_rtt-100-by-node/average_rtt-100-by-nodemkdir

However:

 

$ls /nfs/slac/g/net/pinger/pingerreports/hep/*/*-100-by-node*
/bin/ls: Argument list too long.
Exit 1
