PMHOSTNAME(1)              General Commands Manual             PMHOSTNAME(1)

NAME         top

       pmhostname - report hostname

SYNOPSIS         top

       $PCP_BINADM_DIR/pmhostname [hostname]

DESCRIPTION         top

       pmhostname reports the name of the host hostname as returned by

       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.


       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).
