PingER2 Data Flow

• PingER2 collects and stores data in the directory defined inside pinger.xml configuration file (in SLAC pinger.xml can be found at /afs/slac.stanford.edu/package/pinger/pinger2/share/pinger/pinger.xml). At SLAC this sets the data directory via <DataDirectory>/nfs/slac/g/net/pinger/pinger2/data/</DataDirectory>
