| To make sure all of our public web and FTP servers are running 24 hours a day, we use PageSentry from Maxum Development Corporation. PageSentry simulates a web browser or FTP client and checks each server every few minutes. If a server does not respond, an alert detailing the problem is sent to the alphanumeric pager of the appropriate server administrator. We use an Apple Workgroup Server 8150/110 as our monitoring system. In addition to PageSentry, we use PageNOW! from Mark/Space Softworks as our alphanumeric paging software. |
