Starting from Zabbix 7.0.22, real-time export files created by the ExportDir functionality are created with restricted permissions. The file owner has read/write access, the owner group has read access, and all other permissions are denied. This results in mode 640.

Current behavior:

• ExportDir creates real-time export files with mode 640 since Zabbix 7.0.22.
• There is no Zabbix server configuration parameter to change this mode.
• The available parameters for this feature are ExportDir, ExportFileSize, and ExportType.

Requested behavior:

• Add a Zabbix server configuration parameter to control permissions for files created by ExportDir.
• Keep the current 640 behavior as the default.
• Allow administrators to choose a less restrictive mode when required by their environment, for example 644 or 664.
• Validate the configured value so unsafe or invalid modes are rejected.

Possible implementation:

ExportFileMode=0640

or, if a more specific name is preferred:

ExportDirFileMode=0640
