#Usage: postresql.monitor [options]
#
# --database=<Databasename> indicates the database to which is connected
# --username=<Username> DB-User which is used to connect to the DB
# --password=<Password> DB-Password which is used to connect to the DB

#
# a monitor to determine if a PostgreSQL database server is operational
#
# Rather than use tcp.monitor to ensure that your SQL server is responding
# on the proper port, this attempts to connect to and list the databases
# on a given database server.
#
# This monitor requires the perl5 DBI, DBD::mSQL and DBD::mysql modules,
# available from CPAN (http://www.cpan.org)
