esaProbeHistoryAction is a value that a manager writes to clear the counters held in this specific bin. This is the only way to explicitly zero out a stuck or contaminated bin's counters from the manager side, for example after a known test misconfiguration, rather than waiting for it to naturally roll over. For example, after a technician accidentally runs the probe with the wrong packet size for five minutes, they write this object to clear the tainted bin instead of letting bad numbers sit in the log until the next scheduled rollover.
