Current Failover Link Test Statistics
Position/GPS statistics
The Position statistics show information gathered from attached NMEA-0183 compliant GPS
receivers attached to the Digi device, and statically configured position parameters.
These statistics indicate the successes and failures of the configured link tests, used by the
Network Failover feature to manage the default gateway. For each network interface, the
following counters are maintained and reported. The values indicate the total number for each
interface and category, since the Digi device was last powered on or rebooted.
Test Success
Test Failure
Bypass Test
Consecutive Failures
Link Not Responding
The total number of successful link tests. A link test is successful if either of the configured
tests (primary or secondary destination) succeeds. When a link test succeeds, the interface is
reported as “Responding”.
The total number of failed link tests. A link test fails if both of the configured tests (primary
or secondary destination) fail, or if only one link test is configured and it fails. If two link
tests are configured, and both of them fail, that is counted as a single link test failure for the
purpose of counting failures.
The total number of link tests that were bypassed (not run) for a number of possible reasons.
A link test is bypassed if no destinations are configured, if the interface has no associated
gateway, if the interface goes down while a test is in progress, or if failover is disabled
(turned off) while a test is running (disabled as a feature or for the interface being tested).
The current number of consecutive link test failures for the interface. When the number of
consecutive failures reaches the threshold configured in the Network Failover settings, the
interface is reported as “Not Responding” and the default gateway may be changed as a
result. When a link test is successful, or when the interface goes down and comes back up,
the consecutive failures counter is reset to zero.
The total number of link test failures that occurred for the interface after it has been reported
as “Not Responding”. This counter can be a useful indicator for determining how much time
an interface is in the state of “Not Responding”.
