Probe States

A probe configured on your ProCurve Secure Router is also defined by its
state—either Pass or Fail. The state is determined by the number of tests that
have failed, together with the tolerance setting. For example, you could
configure the tolerance so that a probe fails when 9 out of 10 tests fail or when
20 tests in a row fail.
To run tests, a probe must be active (up). If you manually shut down the probe,
it stops transmitting packets, and its state becomes fixed at Pass, despite any
previous failed tests.

Network Monitor Tracks

By itself, a probe can monitor network conditions, but it cannot take any
action based on its findings. A track is responsible for tying probe findings to
an action.
For example, if you are monitoring a route, the track is what actually removes
a faulty route. Or, if you are using a track to monitor a server, the track is what
logs status changes.

Track Characteristics

A track is defined by the probes (either one or two) that it uses to monitor the
network. In addition, a track is defined by the action that it takes based on its
state.

Track States

Like a probe, a track can have one of two states: Pass or Fail. The state depends
on the state of the associated probe or probes. When a track relies on two
probes, you can configure it to either:
pass only when both probes pass
pass when either one of the two probes passes

Track Actions

A track can take an action based on the results that probes return about
network conditions. You can enable a track to take one or both of these actions
when its state changes to Fail:
remove a route
create a log entry
