## 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.

## OPTIONS

--env=FILENAME
  Load environment from FILENAME before executing the CGI.

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

## ENVIRONMENT VARIABLES

XYMONHOME
  Home directory of the Xymon server files
XYMONSNAPDIR
  Directory where generated snapshots are stored. This directory must be writable by the userid executing the CGI script, typically "www", "apache" or "nobody". Default: $XYMONHOME/www/snap/
