PMHOSTNAME(1) General Commands Manual PMHOSTNAME(1)
pmhostname - report hostname
$PCP_BINADM_DIR/pmhostname [hostname]
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.
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).
