The analyzed data from analyze-all.pl is saved in files of the form below, the contents are described in PingER data flow at SLAC:
/nfs/slac/g/net/pinger/pingerreports/hep/<metric>/<metric>-<len>-<by>-<year>-<month>-<day>.txt.gz#len=100|1000, by=by-node|by-site./nfs/slac/g/net/pinger/pingerreports/hep/minimum_rtt/minimum_rtt-100-by-node-2011-05-01.txt.gz |
See https://confluence.slac.stanford.edu/display/IEPM/PingER+data+flow+at+SLAC for the data flow. The use of the proxy is triggered by the NODEDETAIL Data Server entry (e.g. proxy=1) to tell ping_data.pl to gather the data from the SLAC anonymous ftp server (via the copy)that is basically acting as a proxy.

A possible way to We address items 1 thru 8 for Beijing might be to copy by Beijing copying the files to anonymous incoming FTP at SLAC on a daily basis at the same time the actual data is copied. Thus the files (updated as of the previous night) would be available for review. Since Bejing has a copy of ping_data.pl this could be is used to access the files so they could be copied. can be copied.
- The FTP files are located in: /afs/slac/public/incoming/pinger/proxy/2001:da8:270:2018:f816:3eff:fef3:bd3/web
The NFS files are located in: /nfs/slac/g/net/pinger/pingerdata/hep/data/proxy/2001:da8:270:2018:f816:3eff:fef3:bd3/web/

For the Android some new code would be needed to copy the files to SLAC.
