System Monitor
The System Monitor page is used to configure the behaviour of the Periodic Piing monitor function.
Figure 43 - System Monitor Settings
The Periodic Ping Reset Monitor configures the router to transmit controlled ping packets to 2 specified IP addresses. Should the router not receive responses to the pings, the router will reboot.
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 “Redundant Address”.
3.
The router then sends 3 consecutive pings to the “Destination Address” and 3 consecutive pings to the “Redundant Address” every “Failure Retry Period” configured interval.
4.
If all accelerated pings in step 3 above fail the number of times configured in “Failures Before Reset”, 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 the “Retry Period” field to 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
This facility is available by clicking on the “Services” menu followed by the “System Monitor” menu item on the right.
The router 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.
The default value is 0 which disables the “Forced Reset Every” field. The maximum value is 65535 minutes.
