This DisplayString reports the current scan mode of the fscan agent's file-monitoring subsystem, which watches a log or text file identified elsewhere in the MIB by the filename object. An admin reads it to confirm which mode the agent is using to scan the target file before interpreting the length, lengthrate, and per-pattern match counters reported alongside it. For example, an admin troubleshooting why match counts look wrong would first check this value to confirm the agent is scanning in the expected mode rather than a stale or misconfigured one.
