       pmdacisco - Cisco router performance metrics domain agent (PMDA)

       $PCP_PMDAS_DIR/cisco/pmdacisco  [-d  domain]  [-l logfile] [-U username] [-P password] [-r
       refresh] [-s prompt] [-M username] [-x port] host:interface-spec [...]

       $PCP_PMDAS_DIR/cisco/probe [-P password] [-s prompt] [-U username] [-x port] host

       pmdacisco is a Performance Metrics Domain Agent (PMDA) which extracts performance  metrics
       from one or more Cisco routers.

       A brief description of the pmdacisco command line options follows:

       -d   It is absolutely crucial that the performance metrics domain number specified here is
	    unique and consistent.  That is, domain should be different for every PMDA on the one
	    host, and the same domain number should be used for the same PMDA on all hosts.

       -l   Location  of  the log file.  By default, a log file named cisco.log is written in the
	    current directory of pmcd(1) when pmdacisco is started, i.e.  $PCP_LOG_DIR/pmcd.   If
	    the  log file cannot be created or is not writable, output is written to the standard
	    error instead.

       -P   By default, it is assumed that no user-level  password  is	required  to  access  the
	    Cisco's  telnet  port.  If user-level passwords have been enabled on the Ciscos, then
	    those passwords must be specified to pmdacisco.  If specified  with  the  -P  option,
	    password  will  be	used as the default user-level password for all Ciscos.  See also
	    the INTERFACE IDENTIFICATION section below.

       -r   pmdacisco will refresh the current values for all performance metrics  by  contacting
	    each Cisco router once every refresh seconds.  The default refresh is 120 seconds.

       -s   The  Cisco	command  prompt ends with the string prompt.  The default value is ``>''.
	    The only way pmdacisco can synchronize the sending of commands  and  the  parsing  of
	    output  is by recognizing prompt as a unique string that comes at the end of all out-
	    put, i.e. as the command prompt when waiting for the next command.

       -U   By default, it is assumed that no username login is required to  access  the  Cisco's
	    telnet  port.  If username login has been enabled on the Ciscos, then the correspond-
	    ing usernames must be specified to pmdacisco.  If specified with the -U option, user-
	    name  will be used as the default username login for all Ciscos.  See also the INTER-
	    FACE IDENTIFICATION section below.

       -M   User account under which to run the agent.	The default  is  the  unprivileged  "pcp"
	    account  in  current  versions  of	PCP,  but in older versions the superuser account
	    ("root") was used by default.

       -x   Connect to the Cisco via TCP port number port rather than the default 23 for a telnet

       For  each  interface,  once  the telnet connection is established, pmdacisco is willing to
       wait up to 5 seconds for the Cisco to provide a new snapshot of the requested information.
       If this does not happen, the telnet connection is broken and no values are returned.  This
       prevents pmdacisco tying up  the  Cisco's  telnet  ports  waiting  indefinitely	when  the
       response  from  the router is not what is expected, e.g. if the format of the ``show int''
       output changes, or the command is in error because an interface is no longer configured on
       the router.

       As  each  Cisco	router can support multiple network interfaces and/or multiple communica-
       tions protocols, it is necessary to tell pmdacisco which interfaces are to be monitored.

       The host:interface-spec arguments on the command line define a particular interface  on	a
       particular  Cisco router.  host should be a hostname or a ``dot-notation'' IP address that
       identifies the telnet port of a particular Cisco router.  There are several components  of
       the interface-spec as follows.

	      One  of  the  abbreviations  a, B, E, e, f, G, h, s or Vl respectively for ATM, BRI
	      (ISDN), FastEthernet, Ethernet, FDDI, GigabitEthernet, HSSI, serial or Vlan.

	      Depending on the model of the Cisco, this will either be an integer, e.g. s0, or an
	      integer  followed  by  a slash (``/'') followed by a subinterface identification in
	      one of a variety of syntactic forms, e.g. e1/0, G0/0/1 or s4/2.1.

	      To discover the valid interfaces on a particular Cisco, connect to the telnet  port
	      (using telnet(1)) and enter the command "show int" and look for the interface iden-
	      tifiers following the keywords ``Ethernet'', ``Fddi'', ``Serial'', etc.

	      Alternatively run the probe command.

	      If there is a username login, and it is different to the default (see -U above), it
	      may  be optionally specified here by appending ``@'' and the username to the end of

	      If there is a user-level password, and it is  different  to  the	default  (see  -P
	      above),  it  may	be optionally specified here by appending a question mark (``?'')
	      and the password to the end of interface-spec.

       prompt If the Cisco command prompt is different to the default (see -s above), it  may  be
	      optionally  specified  here by appending an exclamation mark (``!'') and the prompt
	      to the end of interface-spec.

       The following are examples of valid interface-spec arguments.

       The probe command may be used to discover the names of all  interfaces  for  a  particular
       Cisco router identified by host.  The -P argument is the same as for pmdacisco.

       The  parse command takes exactly the same arguments as pmdacisco, but executes outside the
       control of any pmcd(1) and so may be used to diagnose problems with handling a  particular
       Cisco router and/or one of its interfaces.

       Additional  diagnostic  verbosity  may  be produced using the -D appl0,appl1,appl2 command
       line option.  appl0 logs connect and disconnect events, login progress, high-level flow of
       control	and  extracted	statistics.   appl1 traces all commands sent to the Cisco device.
       appl2 logs tokenizing and parsing of the output from the Cisco  device.	 Diagnostics  are
       generated on standard error as each sample is fetched and parsed.

       If  you	want access to the names, help text and values for the Cisco performance metrics,
       do the following as root:

	    # cd $PCP_PMDAS_DIR/cisco
	    # ./Install

       If you want to undo the installation, do the following as root:

	    # cd $PCP_PMDAS_DIR/cisco
	    # ./Remove

       pmdacisco is launched by pmcd(1) and should never be executed directly.	The  Install  and
       Remove scripts notify pmcd(1) when the agent is installed or removed.

       Environment variables with the prefix PCP_ are used to parameterize the file and directory
       names used by PCP.  On each installation, the file /etc/pcp.conf contains the local values
       for these variables.  The $PCP_CONF variable may be used to specify an alternative config-
       uration file, as described in pcp.conf(5).
