Digitemp v2.6
Copyright 1996-2002 by Brian C. Lane <bcl@brianlane.com>


Here are a few useful perl scripts for you to use with DigiTemp. Most of
them need customization for your specific circumstances. Some these scripts
are old, as I now use the RRD tool to graph and log data.

The digitemp_sql.pl script is new, and has not been tested extensivly yet,
but should work for users familiar with the MySQL database system.


inc_temp    Build a file suitable for including into a server side
        include webpage (or modify it to create the whole webpage.
        This script operates on a logfile output from digitemp when
        running with the -l option.

rem_temp    Create an include file as in inc_temp and then send it to
        a server via FTP.
        This script operates on a logfile output from digitemp when
        running with the -l option.

maxplot        Create a GIF image of the temperature graph.
        This script operates on a logfile output from digitemp when
        running with the -l option.

check_digitemp.pl
        This is a NetSaint/Nagios (www.nagios.com) script that uses
        DigiTemp to check temperatures on monitored machines.

digitemp_sql.pl    MySQL database logging of temperatures.

        This is a new script, it logs the serial number and temperature
        in Fahrenheit to a MySQL database. I assume that you are
        familiar with the care and feeding of your database so that I
        can skip over the simple stuff and get to the point:

        Create a new database named digitemp:
        mysqladmin create digitemp -u root -p

        Edit the grant_mysql.sql file and change the password and
        optionally the username. Grant access to the new database:

        mysql mysql -u root -p < mysql_grant.sql

        Create the database table:

        mysql digitemp -u root -p < make_mysql.sql

        Edit the digitemp_mysql.pl script. Change the password to the
        one you used above, optionally change the username.
        Point the digitemp_rcfile variable to the DigiTemp config file
        that you have previously created using digitemp -i -c rcfile

        I recommend using one other than .digitemprc so that it isn't
        accidently erased when you run digitemp -i from your home
        directory.

        Make sure the path to the digitemp binary is correct. It is
        specified by the $digitemp_binary variable.

        Setup a cron job to log temperatures to the database at
        regular intervals:

        */5 * * * *   /home/brian/bin/digitemp_mysql.pl

        At this time I have not written any logging or graphing
        scripts to deal with the MySQL temperature data.
