Src-perl-querylogger

querylogger.pl

This perl script was written to exercise and test the Campbell::Comm module, but may be useful in its own right as a way to interface with dataloggers in batch (i.e., non-interactive) form. Each method in the Campbell::Comm module should be represented by a querylogger command as specified on the command line.

The interface is described if run with no arguments:

   $ querylogger
   syntax: "$ /home/ken/bin/querylogger OPTIONS SITE COMMAND ...
   where OPTIONS are
       --quiet      suppress output to STDOUT
       -q           same as above
       --logfile=f  print everything to file f 
       -l f         same as above
       --comm=s     use rc file section Campbell::Comm-s, or
       -c s         use rc file section Campbell::Comm-s
       --identify   identify site in output (default)
       --noidentify don't identify site in output
   where SITE is one of: site, slope_mtn,
   and COMMANDs may include:
       status       list status strings
       time         show time (setting not yet supported)
       backup=n     n=number of output arrays to spew (no limit)
       MPTR=loc     loc=output storage location (no limit)
       data=n       n=number of data records to get
       binary=n     n=number of data locations to get
       program      print all logger programming
       flags        optionally toggle specified flag(s), show flags
       ports        show ports (toggle not yet supported)
       memory       show mode A memory settings 
       signatures   show mode B signature settings
       input=n[,m][,r-s]  show input storage locations
       capture=[f]  end previous capture, capture output to file f
       get_time_flags experimental using F command

The querylogger (and loggerdata) scripts assume a specific system configuration of sites and rc files; see below...
