How does NetShark Compressed Flow Exports for NetProfiler Feature work ?
Starting in NetShark Version 10.9, NetShark flow exports to NetProfiler are compressed using LZ4 compression to minimize data traffic.
Starting in version 10.9, compressed flow export to a NetProfiler is enabled by default. A new NetProfiler compressed export parameter has been added to the NetShark Advanced Settings page in the NetShark Web interface (Settings > Advanced Settings) to enable or disable NetProfiler flow export compression:
profilerexport.profilers.compression_type.{1|2}={0|1}
profilerexport.profilers.compression_type
parameter is automatically created on the Advanced Settings page (near the bottom of the page).1. Go to the NetProfiler Export page in the NetShark Web interface.
2. Select the Enable Flow Export check box.
3. Add a NetProfiler under NetProfiler for Export.
4. Click Apply.
profilerexport.profilers.compression_type.1=1
2. A new NetProfiler export parameter is added on the Advanced Settings page.
profilerexport.profilers.compression_type.2=1
Flow export compression is automatically enabled. This NetProfiler is currently running version 10.7 software so compressed flows are silently ignored. Flow export compression needs to be disabled for this NetProfiler to receive exported flows from the NetShark
3. Go to the NetProfiler export parameter for this NetProfiler. Disable compressed flow exports by changing the “1” to a “0” in the second value.
4. After making the change click Apply Changes at the bottom of the Advanced Settings page. The NetShark must be restarted for the change to take effect. Click Save Settings to continue, then click Restart Now.
5. After the NetShark restarts, the NetProfiler export parameter on the Advanced Settings page now appears as follows:
profilerexport.profilers.compression_type.2=0
Notes
1. Compressed flow export does not affect NetFlow v9 export.
2. Editing the Advanced Settings page using an unsupported Web browser can lead to errors.
Troubleshooting
If compressed flow exports are not processed properly, please open a TAC case.
