NAME

drawvalmap - Generate a graphical output of validation status values
             encountered by the validator library.

SYNOPSIS

drawvalmap <logfile>

drawvalmap

DESCRIPTION

drawvalmap is a simple utility that can be used to display the validator status values in a graphical format. The input to this script is a set of log messages that can be read either from file or from a socket. The output is an GIF file containing an image of the various validator authentication chain status values.

The script reads data from STDIN if the logfile and the socket option are both unspecified. If the -f option is given, the output GIF file is embedded in an HTML file with the given name. The HTML file auto-refreshes according to the refresh time supplied by the -r option, allowing changes to the validator graph to be constantly tracked.

The typical usage of this script is in the following way:

bash# drawvalmap <logfile>

It would not be uncommon to use this script for troubleshooting purposes in which case output generated by a driver program would be ``piped'' to this script in the manner shown below.

bash# validate -o6:stdout secure.example.com. | drawvalmap -f val_log_map.html

In each case the script generates the results in a ``val_log_map.gif'' file. In the second case, an HTML file with the name val_log_map.html is also generated.

OPTIONS

-s

This changes the mode of operation to read input from a socket. The default address and port to which drawvalmap binds is 127.0.0.1:1053

-a <IP address>

This changes the address to which drawvalmap binds itself to the specified value. This option takes effect only if the -s option is also specified.

-p <port>

This changes the port to which drawvalmap binds itself to the specified value. This option takes effect only if the -s option is also specified.

-h <file.html>

This creates an html file with the given name, which contains the gif image of the validation map.

-r <refresh period>

This changes the refresh period in the HTML file to the given value. The default is 5 seconds.

-g <file.gif>

This changes the name of .gif file to the given value.

-i <ignore_pattern_string>

This causes drawvalmap to ignore log records that match the given ignore pattern.

-m <match_pattern_string>

This causes drawvalmap to include only log records that match the given pattern. If a given log record matches a pattern given by the -m option and also matches the pattern given by the -i option the effective result is that of ignoring the record.
