This is the current operational state, such as running, stopped, or error, of a specific log-reading job. This is the field an admin checks per job when only one of several log feeds into SmartEvent has gone stale, since it isolates the problem to that specific job rather than the whole Correlation Unit. For example, this job's state reading Error while sibling jobs all show Running would isolate a log-reading fault to just that one Log Server's feed.
