Troubleshooting the GigaStor Control Panel

Troubleshooting the GigaStor Control Panel
Use the information in this section to assist you if you have a problem with the
GigaStor Control Panel.
GigaStor Control Panel option is grayed out
If the Capture > GigaStor Control Panel option is grayed out and unavailable, one
of two things has likely occurred.
♦
You are not looking at a probe instance (passive or active) from the
GigaStor probe. Verify you are using a probe instance for the GigaStor
probe. If you are, then consider the next option.
♦
You are viewing a Packet Capture instead of the GigaStor Control Panel.
You can only view one or the other. You cannot view both simultaneously.
Close the Packet Capture window, then choose Capture > GigaStor Control
Panel.
Now that you are viewing the GigaStor Control Panel, you may want to change
your packet capture scheduling and ensuring that you do a “GigaStor” capture
rather than a packet capture.
GigaStor is full or does not have the history you expect
Your GigaStor has storage space to capture your network’s traffic. The GigaStor
probe will save data until its hard drives are full (or you fill the storage capacity
of a GigaStor Software Edition), then one of two things will happen.
The GigaStor will stop capturing packets and saving them to disk or it starts
overwriting the oldest data first so that you have a rolling window of capture.
The option that controls how the GigaStor behaves in the Settings—General
Options tab.
If you do not have as much history as you think you should, then consider:
♦
Pre-filtering your captures. Although this will provide more space for your
captures, by definition you are excluding some traffic. The traffic you
exclude may be just the traffic you need to analyze at some point.
♦
Capturing only partial packets. If you do not need to analyze the payload
of every packet, then consider capturing the headers of packets.
♦
Purchasing a larger capacity GigaStor hardware probe or software license.
TCP applications are not appearing in the GigaStor Control
Panel
If the GigaStor Control Panel is not displaying all of the applications you expect
to see, ensure the “Limit to ports defined in Protocol Definitions” in Settings
>General is unchecked.
Loading decodes in Observer is slow
If your Observer is taking a long time to load a decode from a GigaStor probe,
you may be attempting to mine too much data. Too improve performance, use
