Capturing packets with the GigaStor
214 GigaStor (23 Feb 2018) — Archive/Non-authoritative version
Setting a schedule for when data captures should occur
One way to ensure you always have timely packet captures is to schedule them.
For example, you may want to automatically start a packet capture at the
beginning of business hours each day; you can accomplish this by scheduling
your packet captures accordingly.
To schedule packet captures to begin at preset times, complete the following
steps:
2. Click the Settings button.
The GigaStor Settings window appears.
3. Click the Schedule tab .
4. Select one of the following scheduling types. For the GigaStor active instance
you should choose
Always
unless you have a specific reason to choose a
different option.
●
No scheduling—captures are never scheduled
●
Always—capture runs at all times
●
Daily at specified times—capture runs at same time each day
You must specify a capture begin and end time by clicking the Add button
for each day you select. Multiple time intervals are configurable, per day, if
the times do not conflict.
5. In the Reserve scheduling for section, select GigaStor and click OK .
You may receive a notice about scheduling reservation. If you do, click Yes to
change the scheduling.
6. Click OK to confirm and save your changes
Trimming data from your captures for space or privacy
Typically, packet headers contain the most useful information because
they contain routing information and protocol information. The packet
payload counterpart, however, is sometimes wasteful to collect because most
troubleshooting is done just with the header and the payload may contain
sensitive information.
Under these circumstances, you may want to truncate most payload data from
the packet header(s). In Observer, the result is a partial packet capture .
Some benefits of partial packet captures include:
♦
Smaller capture sizes
●
More overall storage space for packet captures
●
Greatly increases the effective storage size of a GigaStor (or other
capture buffer)
♦
Performance metrics remain intact
♦
Increased overall privacy
♦
Least resource intensive capturing
Some disadvantages of partial packet captures include:
♦
Not all network traffic is stored to disk
