MON version 0.37k
- -----------------

WHAT IT IS
- ----------

    An extensible service monitoring daemon which can be used to monitor
    network or non-network resources.  Written in Perl 5, this code should
    be able to run out-of-the-box on many platforms. It supports a flexible
    configuration file, and can send out email, alphanumeric pages, or any
    other type of alert when it detects the failure of a service. Service
    monitors that come with the distribution can test ping, telnet, ftp,
    smtp, http, nntp, pop3, imap, disk space, SNMP queries, and arbitrary
    TCP services.


Changes since last announcement:
- --------------------------------

- -Fixed problem where ftp.monitor defaults to the SMTP port instead of
 FTP! Thanks to ryde@tripnet.se for pointing this out :)

- -alanr@bell-labs.com added "-u" flag to http.monitor so that you
 can specify the URL to get.

- -Added hpnp monitor, which uses SNMP to query your HP JetDirect
 boards in your printers, and warns you when things go awry.
 For example, if there is a paper jam, mon can send out email
 telling you exactly that, and it includes in the mail the
 current readout on the printer's LCD.

- -Added netappfree.monitor, which uses SNMP to get the free space
 from Network Appliance filers. Uses a configuration file to
 set low-watermarks for each filer.

- -Added process.monitor (thanks to Brian Moore), which 
 queries the UCD SNMP agents to determine if there are errors with
 particular processes on a machine. This is very useful for monitoring
 those processes which seem to die off on occasion :)


AVAILABILITY

REQUIREMENTS
- ------------

    "mon" uses Perl 5.n, where n >= 004.

    You'll need the Time::Period module, available from your local
    CPAN archive (http://www.perl.com/perl).

    The monitors that come with the distribution are all optional, and
    are not required for the normal operation of the daemon. However,
    you'll probably want to use most of them.

    Different monitors and alerts may require some extra Perl modules,
    or some auxiliary programs. Follow the specific instructions for
    each monitor or alert.
