 In case data cannot be written to the export file or the export file cannot be renamed or new one cannot be created after renaming it, Zabbix will retry with 10 second interval until success. In case data cannot be written to the export file or the export file cannot be renamed or new one cannot be created after renaming it, Zabbix will retry with 10 second interval until success.
  
-The following ​information is exported: +For precise details on what information is exported, see the [[:manual/​appendix/​protocols/​real_time_export|export protocol]] page.

-  * for events - host groups, host name, trigger name, timestamp, event status +
-  * for values - host groups, host name, item ID, item name, item value, timestamp, application +
-  * for trends - host groups, host name, item ID, item name, item value (avg, min, max, count), timestamp, application+
  
 Note that host/item can have no metadata (host groups, host name, item name) if the host/item was removed after the data was received, but before server exported data. Note that host/item can have no metadata (host groups, host name, item name) if the host/item was removed after the data was received, but before server exported data.

-Real-time export of trigger events, item values and trends is configured by specifying a directory for the export files - see the ExportDir parameter in server [[:​manual/​appendix/​config/​zabbix_server|configuration]]. ​+Real-time export of trigger events, item values and trends is configured by specifying a directory for the export files - see the ''​ExportDir'' ​parameter in server [[:​manual/​appendix/​config/​zabbix_server|configuration]].

 +Another parameter - ''​ExportFileSize''​ may be used to set the maximum allowed size of an individual export file. When a process needs to write to a file it checks the size of the file first. If it exceeds the configured size limit, the file is renamed by appending .old to its name and a new file with the original name is created.
  
-Another parameter - ExportFileSize may be used to set the maximum allowed ​size of an individual ​export file.+<note important>​A file will be created per each process that will write data (i.e. approximately 4-30 files). As the default ​size per export file is 1G, keeping large export files may drain the disk space fast.</​note>​
