NAME

       snapshot.cgi - CGI program to rebuild the Xymon webpages for a specific point in time.

SYNOPSIS

       snapshot.cgi

DESCRIPTION

       snapshot.cgi  is invoked as a CGI script via the snapshot.sh CGI wrapper.  It rebuilds the
       Xymon web pages to the look they had at  a  particular  point  in  time,  based  upon  the
       historical information logged about events.

       snapshot.cgi is passed a QUERY_STRING environment variable with the following parameters:

          mon (Start month of the snapshot)
          day (Start day-of-month of the snapshot)
          yr  (Start year of the snapshot)
          hour (Start hour of the snapshot)
          min  (Start minute of the snapshot)
          sec  (Start second of the snapshot)

       The  "month"  parameters  must  be  specified  as  the  three-letter  english  month  name
       abbreviation: Jan, Feb, Mar ...

       "day" must be in the range 1..31; "yr" must be specified including century (e.g.  "2003").
       "hour" must be specified using a 24-hour clock.

       All  of  the  processing involved in generating the report is done by invoking xymongen(1)
       with the proper "--snapshot" option.

       xymongen-options
              All options except "--env" are passed on to the xymongen(1)  program  building  the
              snapshot files.
