NAME¶
pmhostname - report hostname
SYNOPSIS¶
$PCP_BINADM_DIR/pmhostname [
hostname]
DESCRIPTION¶
pmhostname reports the name of the host
hostname as returned by
gethostbyname(3N).
If
hostname is not specified, then the local host name is retrieved using
gethostname(2) and this is than passed to
gethostbyname(3N).
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(3N) 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).
