Overview - Perimeter911

Technical Overview

PERIMETER911 probes operate as follows:

On a 5 or 15 minute cycle, P911 attempts to contact your facilities using prototocols designated by you. eg http, https, smtp, pop3, imap, ftp.
The result is logged. (Logs are always available for your inspection.)
In the event that your facilities do not respond or do not respond as expected, a double-check is made, ie: a second probe is conducted from an entirely different machine. This too is logged.
If neither contact attempt is successful, P911 recognizes this as a potential alarm condition.

Potential alarm conditions are recognized as real alarm conditions according to rules which include:

Have you requested alarm notification?
Are your facilities currently in scheduled maintenance mode?
Have you stipulated that alarms are not to be issued until two consecutive cycle runs confirm the error condition as on-going?
Have alarms already been issued for this particular error condition?

PERIMETER911 alarms operate as follows:

If electronic alerting has been enabled, P911 sends a message to your desired email address(es) which typically results in text messaging to your pager or cellular phone.
Following the issuance of an electronic alert, P911 sends an "ALL CLEAR" message when the problem has been resolved.
If SOS alerting has been enabled, P911 dispatch operators will attempt to track you down using your emergency contact information.
If SOS alerting has been enabled as an escalation contingency, P911 operators will only attempt to contact you if an alert condition persists beyond some pre-determined length of time.
