    XMLWordPrintable

Details

    Description

      When history syncer tries to evaluate a trigger expression it makes a SQL query to database which selects all unique hostid related to the trigger.
      The query is performed for each trigger having a user macro.

      We should use cache instead of SQL queries in this case.
