Configuring your GigaStor
200 GigaStor (23 Feb 2018) — Archive/Non-authoritative version
means that information on the Statistics tab at the bottom of the GigaStor
Control Panel is dependent on which physical ports are selected.
2. Click the Settings button.
3. Click the General Options tab.
See Setting the GigaStor general options (page 189) 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
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:
