      Description

      Item key: log[/var/log/

      {HOSTNAME}.log]
      Trigger: {localhost:log[/var/log/{HOSTNAME}

      .last(#2)}

      It seems the problem is caused by escalator expands macros in item key's option.

      (1) Item key setting: log[/var/log/{HOSTNAME}.log]
      (2) Expand {TRIGGER.KEY}

      macro by escalator: log[/var/log/localhost.log]

      (1) and (2) is not equal, so escalater can not handle history data correctly.
      Actually, I added log[/var/log/localhost.log] item,
      events generated by log[/var/log/

      {HOSTNAME}

      .log] item used hisotry of log[/var/log/localhost.log].
