pmhostname: report hostname
NAMEpmhostname - report hostname
DESCRIPTIONpmhostname reports the name of the host hostname as returned by 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.
PCP ENVIRONMENTEnvironment 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).
