Learn how to configure packet capture and buffer sizes, define subnets, and change the storage directory where packets and other data is stored.
Defining your subnets in GigaStor
You can specify subnet properties for the GigaStor to allow for statistical aggregation of devices within the Statistics tabs in GigaStor Control Panel.
1. On the Home tab, in the Capture group, click GigaStor.
2. Click the Settings button.
3. Click the Subnet tab.
4. Use the Add, Delete, Modify, Import, and Delete All buttons to configure the subnet settings for the GigaStor. When you define subnets in the GigaStor Control Panel, Observer adds that subnet information to its index files. All future data analyzed will have subnet filtering readily available as well as statistical data. On the IP Stations tab you see your subnets and you can perform statistical analysis based on subnets.
When you analyze data from captures with index files without any subnets defined, there will be no subnet available in the IP stations tab even if the analyzed data includes some index files with the new subnet information.
Tip! You can import subnet ranges using an ipsubnetrange file. See Structure of an .ipsubnetrange file.
 
 
Tracking individual analysis ports
Revised: 2017-05-26
When using the capture card in your GigaStor, you can track statistical information per physical port.
Data captured by the capture card is indexed to show on which port the data arrived. You can further choose to use physical ports to filter statistics. This means that information on the Statistics tab at the bottom of the GigaStor Control Panel is dependent on which physical ports are selected.
1. On the Home tab, in the Capture group, click GigaStor.
2. Click the Settings button.
3. Click the General Options tab.
See Setting the GigaStor general options for a description of each field of the GigaStor General Options tab.
4. Enable these two options:
Track statistics information per physical port
Use physical port selections to filter statistics
 
 
Configuring the packet capture and GigaStor buffer size
Allows you to set the amount of RAM that Observer will dedicate to the capture buffer cache for this instance. This configuration value has been pre-set for optimum performance given a single active GigaStor monitoring instance. The default settings allows enough memory to set up a number of passive GigaStor instances.
If you wish to run multiple active monitoring instances to watch multiple links or networks, you can decrease the capture buffer size dedicated to GigaStor collection, which frees some memory for creating other probe collection instances. Inadequate memory allocation to GigaStor collection can affect performance and result in dropped packets during high load periods.
A GigaStor Instance can be as large as the physical memory installed on your system after subtracting the memory dedicated to Windows and other probe instances.
To change the allocation for this probe instance, click the Configure button, which will display the probe instance, Memory and Security Administration dialog.
In all cases, the actual buffer size (Max Buffer Size) is also reduced by 7% for memory management purposes. Should you try to exceed the Max Buffer Size an error dialog will be displayed indicating the minimum and maximum buffer size for your Observer (or probe) buffer.
How to change the GigaStor storage directory or drive
Created: 2015-12-03
You can change the directory where packets collected by your GigaStor are stored. However, if you are using a GigaStor hardware appliance, this should always remain set to D:\DATA.
This can also be performed on any Observer and is not limited to the GigaStor.
 
Some reasons for changing the GigaStor storage directory include:
You are using the GigaStor Software Edition and need to store packets somewhere else than the C:\ drive.
You regularly schedule packet captures, so you want those captures to be saved in a specific location.
You need to store packet captures on a higher capacity hard disk.
To change the directory where collected packets are stored:
1. Click the File tab, and click Options > General Options.
2. Click the Folders tab.
3. Change the directory used for packet captures.
Caution: If you are using a GigaStor hardware appliance, this should always remain set to D:\DATA.
