Описание (Description)
pmdaOpenLog
redirects stderr to the logfile specified in the
dispatch structure, set by the previous call to pmdaDaemon(3) or
pmdaGetOpt(3). The first line of the log file will detail the
name of the calling process, the host the process is running on,
and the current time. In addition, the log is appended with the
exit time of the process by a routine registered with atexit(3).
Предостережение (Caveat)
The PMDA must be using PMDA_PROTOCOL_2
or later, as specified in
the call to pmdaDSO(3) or pmdaDaemon(3).
Окружение PCP (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). Values for these variables may be obtained
programmatically using the pmGetConfig(3) function.
