System Monitor
The System Monitor page is used to configure the behaviour of the Periodic Ping monitor function.
The Periodic Ping Reset Monitor configures the router to transmit controlled ping packets to user specified IP addresses. Should
the router not receive responses to the pings, the router will reboot. The purpose of this feature is to ensure the recovery of the
router if the internet connection disconnects and does not reconnect for any reason.
This works as follows:
1. After every "Periodic Ping Timer" configured interval, the router sends 3 consecutive pings to the "Destination Address".
2. If all 3 pings fail the router sends 3 consecutive pings to the "Second Address".
3. The router then sends 3 consecutive pings to the "Destination Address" and 3 consecutive pings to the "Second Address"
every "Periodic Ping Accelerated Timer" seconds.
4. If all accelerated pings in step 3 (above) fail the number of times configured in "Fail Count", the router reboots.
5. If any ping succeeds the router returns to step 1 and does not reboot.
Please note: The "Periodic Ping Timer" should never be set to a value less than 60 seconds; this is to allow the router time
to reconnect to the cellular network following a reboot.
How to Disable the Periodic Ping Monitor
To disable the Periodic Ping Reset Monitor simply set to "Fail Count" 0
Please note: The traffic generated by the periodic ping feature is counted as chargeable usage, please keep this in mind
when selecting how often to ping.
How to configure a Forced Reset
Also known as an automatic reboot this facility can be configured to automatically reboot after a period of time specified in minutes.
While this is not necessary, it does ensure that in the case of remote installations, it will reboot the router if some anomaly occurs.
This feature is available by clicking on the "Services" menu followed by the "System Monitor" menu item on the right.
The default value is 0 which disables the Forced Reset Timer. The maximum value is 65535 minutes (1092.5 hours or 45.5 days).
