Use throughput graphs, driver statistics, and the SNMP
GET request to gather information for capacity planning.
Throughput graphs
Throughput graphs show
the sum of traffic, in megabits, into or going out of your network.
Throughput graphs also show the totals for unanalyzed traffic and
secured traffic moving through your network. Unanalyzed traffic has
not been inspected by the Protocol Analysis Module (PAM). Secured
traffic has been inspected by PAM, but this does not necessarily mean
that the traffic is suspect. You can customize these graphs to show
statistics for an hour, a day, a week, or a month. Choose the time
period that best helps you to view the capacity of traffic and analysis
on your appliance.

Driver statistics
Driver statistics help
with capacity planning because they report the totals for secured
traffic, unanalyzed traffic, packets received, and packets transmitted
for drivers. The four specific driver statistics that help with capacity
planning are:
- adapter.bytes.secured: Lists the total number
of bytes secured.
- adapter.bytes.unanalyzed: Lists the total
number of bytes unanalyzed.
- adapter.0.packets.received: Lists the number
of packets received on adapter 0 (adapter A).
- adapter.0.packets.transmitted: Lists the
number of packets transmitted (forwarded from inline partner or injected)
on adapter 0 (adapter A).

SNMP GET request and the MIB file
The SNMP
GET request helps with capacity planning because you can configure
it to retrieve statistics from the management information base (MIB)
file. The MIB file includes information
about these items:
- network.driver.stats: Contains all of the
statistics found in .
- protection.analysis.stats: Contains all of
the statistics found in .
- network.protection.stats: Contains all of
the statistics found in .
- ipmi.chassis.status (only for GX7000 series
appliances): Contains information about the status of the chassis
along with information about power failures and driver failures. You
can view this status in the Intelligent Platform Management Interface
(IPMI).
Configure the SNMP GET request in . Then use an SNMP tool to get the MIB file contents
from
MIB: NET-SNMP-EXTEND-MIB:nsExtendOutput1Table.
Note: This
capacity planning feature is available only when the SNMP GET request
is enabled and configured.
