NAME

na_ftp - display FTP statistics

SYNOPSIS

ftp stat [ -i ipv4|ipv6 ] [ -p native|implicit|explicit ]

ftp stat [ -z ]

DESCRIPTION

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.

EXAMPLES

  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
