NAME
       pmhostname - report hostname


SYNOPSIS
       $PCP_BINADM_DIR/pmhostname [hostname]


DESCRIPTION
       pmhostname reports the name of the host hostname as returned by gethostbyname(3).

       If hostname is not specified, then the local host name is retrieved using gethostname(2) and this is than
       passed to gethostbyname(3).

       pmhostname provides a service for shell scripts that mimics the logic formerly used  by  Performance  Co-
       Pilot  applications when trying to determine the official name of a host.  PCP applications no longer use
       DNS-based heuristics, and therefore this command is deprecated.

       If  gethostbyname(3)  fails,  the  input  host  name  (either  hostname  or  the  result   from   calling
       gethostname(2)) is reported.


PCP ENVIRONMENT
       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 configuration file, as described in pcp.conf(5).
