Use a separate subfolder for each hosts RRD files. The naming of the RRDfiles will be one of the following:<br><ul><li><path_cacti>/rra/host_id/local_data_id.rrd,</li><li><path_cacti>/rra/device_id/data_query_id/local_data_id.rrd,</li><li><path_cacti>/rra/device_hash/device_id/local_data_id.rrd,</li><li><path_cacti>/rra/device_hash/device_id/data_query_id/local_data_id.rrd.</li></ul><br>You can make this change after install by running the CLI script <b>structure_rra_paths.php</b> after you make the change. NOTE: If you change Max Directories value to decrease the number of directories, or if you change the Directory Pattern, empty directories will not be pruned after you rerun the <b>structure_rra_paths.php</b> script.

Which Directory Pattern do you wish to use for Structured RRD Paths. 'Device ID' is the default. The setting 'Device ID/Data Query ID' should be used when you have Devices with thousands of Graphs. After Changing the Directory Pattern, you must run the Structured Path CLI script again to modify the RRDfile paths to the new Pattern.
