Long-Term Capture
The long-term capture feature expands the number of use cases for ProfiShark. By combining the capture capabilities of ProfiShark with the storage capabilities of a NAS, it becomes possible to capture traffic for extended periods of time, making it easier to catch intermittent network problems in the act.
The ProfiShark USB key package (included with the product, and also available at resources.profitap.com) provides packages for various Synology architectures.
Install the package corresponding to your Synology NAS (see Synology NAS).
For optimal capture results, an Intel-equipped Synology NAS is recommended.
| Device status | Displays the connected TAP and its MAC address. |
|---|---|
| Capture status | Specifies whether the capture process is in progress. |
| Total captured | Displays the total amount of data captured. |
| Dropped by software | Displays the amount of packets dropped due to performance issues or buffer overflow. |
| Inline ports | By default, the ProfiShark ports are set to In-Line Mode, meaning that devices connected through ports A and B can communicate. In this case, both ports are controlled at the same time. Unchecking “Inline ports” enables SPAN mode, setting the ProfiShark to intercept two separate data streams. In this case, communication between devices connected to ports A and B is severed, and ports A and B can be controlled independently in terms of speed, duplex mode, and autonegotiation. |
| Capture directory | Allows users to select the destination folder of the capture file. |
| Ring buffer | If enabled, overwrites old data, using the circular buffer method of storing new data at the beginning of an existing data file. |
| Maximum files | After reaching the configured maximum file duration or size, the captured traffic will be saved in a new file, until the number of files configured here is reached. |
| Maximum file size | This option sets the maximum file size allowed for storing the captured data. Exceeding this value will result in stopping the capture or storing the capture data in a new file. |
| Maximum file duration | This option sets the maximum duration for storing the captured data. Exceeding this value will result in stopping the capture or storing the capture data in a new file. |
| Statistics | Displays ongoing and total traffic data for both port A and port B. |
