It is possible to configure real-time exporting of trigger events, item values and trends in a newline-delimited JSON format.
Exporting is done into files, where each line of the export file is a JSON object. Value mappings are not applied.
In case of errors (data cannot be written to the export file or the export file cannot be renamed or a new one cannot be created after renaming it), the data item is dropped and never written to the export file. It is written only in the Zabbix database. Writing data to the export file is resumed when the writing problem is resolved.
For precise details on what information is exported, see the export protocol page.
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 configuration.
Two other parameters are available:
ExportFileSizemay 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.
ExportTypeallows to specify which entity types (events, history, trends) will be exported. This parameter is supported since Zabbix 5.0.10.
