Statistics processing scripts (README)This directory contains a number of scripts for use with the filegenfacility. Those files ending in .awk are for the Unix awk utility, whilethose ending in .sh are for the csh utility. Normally, the summary.shscript is called from a cron job once per day. This script processes thedaily loopstats, peerstats and clockstats files produced by the daemon,updates the loop_summary, peer_summary and clock_summary archive files,and deletes the daily files.In the case of the Austron 2201A GPS receiver, the clockstats filecontains a wealth of additional monitoring data. These data are summarizedand writted to the clock_summary file, then a series of special files areconstructed for later processing by the S utility.The summary.sh script invokes a number of awk scripts to actually producethe data. This may result in multiple scans of the same input file.The input file is deleted after processing. In fact, the shell scripts willprocess all input files found of the correct type in chronological order,deleting each one as it is scanned, except the current day file.The summary.sh script can produce input files for the S utility, if itis found on the search path. This utility makes PostScript graphs of theloopstats data for each day, as well as various statistics produced bythe Austorn 220aA GPS receiver. The S utility is automatically runas a background job. Its control files have the .S extension.The psummary.awk script can be used to scan the peer_summary file andconstruct an historical reprise of the daily summaries. The file formats are documented in the README.stats file and in thescripts themselves. Further detail on the radio clock ASCII timecodeformats and related data are in the README.timecode file.David L. MillsUniversity of Delawaremills@udel.edu1 November 1993Revised 12 April 1994
