- Stores raw data on nfs at:
Code Block /nfs/slac/g/net/pinger/pinger2/data/ping-<YYYY>-<MMM>-<MM>.txt e.g. /nfs/slac/g/net/pinger/pinger2/data/ping-2011-02.txt
- Ping_Data
- /afs/slac/g/www/cgi-wrap-bin/net/offsite_mon/ping_data/ping_data.pl
- Represents the web interface(cgi script) used to fetch data from remote monitoring node.
- zips the data before transfer.
- GetData
- /afs/slac/package/pinger/getdata.pl
Wiki Markup queries ping_data\[[http://slac.stanford.edu/cgi-wrap/ping_data.pl]\] to fetch data.
- Stores zipped File at
Code Block /nfs/slac/g/net/pinger/pingerdata/hep/data/<host>/ping-<YYYY>-<MMM>.txt.gz
- See Restoring PingER data for more details.
- Analyze
- There is a group of analysis scripts, that pick up zipped data; do their analysis, aggregate data and prepare web reports.
- The first script to be executed is analyze-hourly.pl which takes as input data the output of getdata.pl and from this aggregaytes the data to by day and writes it to the /nfs/slac/g/net/pinger/pingerreports/hep/<metric>/ directory with the file name <metric><size><by><yyyy><mm>-<dd>.txt.gz,
Example output filename:
Example output format (there are 24 hourly lines like this per day/per host pair):Code Block /nfs/slac/g/net/pinger/pingerreports/hep/minimum_rtt/minimum_rtt-100-by-node-2006-09-28.txt.gz
Code Block icfamon.dl.ac.uk lns62.lns.cornell.edu 108.871 ... 109.620 icfamon.dl.ac.uk lns62.lns.cornell.edu
- The remaining analyze scripts (analyze-daily.pl, analyze-monthly.pl, analyze-allmonths.pl, and analyze-allyears.pl) take as input the data from analyze-hourly.pl ancd create files of the form:
Code Block /nfs/slac/g/net/pinger/pingerreports/hep/<metric>-<size>-by-<site|node>(-<YYYY>?)(-<mm>?)(-<dd>?).txt.gz
- More information can be found on running getdata.pl and the analyze scripts to recover missing data.
