na_ftp - display FTP statistics
ftp stat [ -i ipv4|ipv6 ] [ -p native|implicit|explicit ]
ftp stat [ -z ]
The ftp stat command is used to display FTP and FTPS
statistics and to reset counters. "Native FTP" refers to
the normal FTP connections where communication between the
client and the server takes place in clear text. "Implicit
and Explicit FTPS" refer to the two modes of FTPS connections
where the FTP communication is SSL encrypted and
secure.
If issued without any arguments, the command reports the
cumulative values of FTP connection counters: the current
number of connections, the highest number of simultaneous
connections, and the total number of connections for all
the connections established over Native FTP, Implicit FTPS
or Explicit FTPS and over both IPv4 and IPv6.
The -i option reports the counters after filtering connections
on the basis of the IP protocol used. When the -i
option is used with "ipv4" as the argument, counters corresponding
to the connections over the IPv4 protocol are
displayed. When the -i option is used with "ipv6" as the
argument, counters corresponding to the connections over
the IPv6 protocol are displayed.
The -p option reports the counters after filtering connections
on the basis of the FTP flavor used. When the -p
option is used with "native" as the argument, counters
corresponding to the Native FTP connections are displayed.
When the -p option is used with "implicit" as the argument
counters corresponding to Implicit FTPS are displayed.
Similarly the argument "explicit" displays counters corresponding
to Explicit FTPS connections.
The -z option resets the simultaneous connection and total
connection counters to zero.
Here are some examples using ftp stat:
ftp stat
Current connections: 6 (native 2, implicit 2, explicit 2)
Maximum concurrent connections: 10
Total connections: 21
ftp stat -i ipv4
Current IPv4 connections: 3
Maximum IPv4 concurrent connections: 6
Total IPv4 connections: 15
ftp stat -i ipv6
Current IPv6 connections: 3
Maximum IPv6 concurrent connections: 4
Total IPv6 connections: 6
ftp stat -p native
Current native connections: 2
Maximum native concurrent connections: 6
Total native connections: 12
ftp stat -p explicit
Current explicit connections: 2
Maximum explicit concurrent connections: 2
Total explicit connections: 4
ftp stat -p implicit
Current implicit connections: 2
Maximum implicit concurrent connections:3
Total implicit connections: 5
ftp stat -i ipv4 -p implicit
Current implicit IPv4 connections: 1
Maximum implicit IPv4 concurrent connections: 2
Total implicit IPv4 connections: 3
ftp stat -z
Current connections: 6 (native 2, implicit 2, explicit 2)
Maximum concurrent connections: 10
Total connections: 21
FTP connection counters set to zero
ftp stat
Current connections: 6 (native 2, implicit 2, explicit 2)
Maximum concurrent connections: 0
Total connections: 0
