    Description

      Zabbix creates "down"/"lost" events even if the host is available.
      Sometimes (I didn't find a pattern yet) down hosts will become "lost" leading to a discovery event the next time they show up (instead of a normal "up").

      Maybe it's just a misunderstanding, but I couldn't find any documentation when being "down" will lead to be "lost".

      // SQL query to get the raw data
      SELECT e.value, FROM_UNIXTIME( e.clock, '%Y-%m-%d %H-%i-%s' ) AS date
      FROM `events` AS e
      LEFT JOIN dservices AS ds ON e.objectid = ds.dhostid
      WHERE e.source =1
      AND e.object =1
      AND ds.ip LIKE '10.222.111.58'
      ORDER BY ds.ip DESC , e.clock DESC
