Problem:
Calculating Throughput on the ASA
Solution:
For Calculating Throughput on the ASA, We have to add received or Transmit traffic in bytes/sec on all physical interfaces:
26066000 + 23001 + 12071002 = 38160003 Bytes/sec
Then you will need to convert that to Mb/seconds for that you will need to partition that into 1024 to get the kbps and then the
result into 1024 again to get the Mbps.
38160003*8 = 305280024/1024*1024 = 291 Mbps(Approx)
Example:

Outputs (which we calculated in order to get the throughput):
We have to add receive traffic on Physical interfaces:
26066000 + 23001 + 12071002 = 38160003 Bytes/sec
38160003*8 = 305280024/1024*1024 = 291 Mbps(Approx)

we can monitor the bandwidth through Graphs in the Firewall Dashboard.

Thanks

Great document Azmat...Very helpful!!
Why
38160003*8 = 305280024/1024*1024 = 291 Mbps(Approx)
?!?
Storage (Kilo = 1024 bits)
Bandwidth (Kilo = 1000 bits)
http://physics.nist.gov/cuu/Units/binary.html
so
38160003 = megabits 305.280024
Hi Azmat Ali, I am getting below different values for recvd and transmit, which one to be considered here ?
Traffic | bytes/sec | Mbps |
recvd | 38160003 | 291.1377 |
trasmitt | 103252006 | 787.7503 |
Hello azali and all:
Is not this wrong equation?
38160003*8 = 305280024/1024*1024 = 291 Mbps(Approx)
it should be
38160003*8 = 305280024 bits = (305280024/1000) Kbps = 305280.024/1024 = 291 Mbps(Approx) notice I removed *1024 which I think is confusing and move bits to Kbps so result will reflect Mbps
There is also some documentation that indicates 1000Kbps = 1Mbps and other 1024Kbps = 1Mbps
Please note: "Decimal multiples" not Binary or when it is Binary related.
Refer to: "Decimal multiples" not Binary.
www.checkyourmath.com/convert/data_rates/per_second/kilobits_megabits_per_second.php
and Binary:
1 kb/s = 0.0009765625 Mb/s
1 Mb/s = 1024 kb/s
