A method and apparatus for monitoring and maintenance of unattended
robot liquid storage and dispensing sites, including
a site controller and site monitor. The site monitor continuously appends text strings received from the site controller to
HTML text log files and HTLM text report files and simultaneously compares the stored text strings representing site events to be monitored with evaluation messages. Each evaluation message is linked to an alert code, which in response to an evaluation message
text string match initiates a particular set of responses, including sending notice of site failures and other remote site information to a home office via fax,
pager and / or email. The site monitor also collects the information gathered from the site controller, the tank monitor, alarm
system and any other site devices and stores the information in a one or more
HTML text files, which information then takes the form of a
web page with
hypertext links to images related to the stored information.
