Описание (Description)
These routines provide standard handling for error messages from
within the internals of Performance Co-Pilot (PCP) daemons and
Performance Metric Domain Agents (PMDAs).
pmNotifyErr is a printf(3) style function that will format
message (and any subsequent arguments) with a prefix that
includes the current date and time from ctime(3), the name of the
application from pmGetProgname(3), the process's id from
getpid(2) and the priority.
priority should be one of the level LOG_ macros defined for
syslog(3). Most typically this would be LOG_INFO, LOG_WARNING or
LOG_ERR.
pmNotifyErr writes to standard error, which for daemons and PMDAs
has most likely been redirected to a log file using pmOpenLog(3).
Additionally message (and any subsequent arguments) may be sent
forwarded to syslog(3) if pmSyslog has previously been called
with onoff having a non-zero value.
Forwarding to syslog(3) can be disabled at any time by calling
pmSyslog with onoff having a zero value, and this is the starting
state for each PCP application.
In the style of syslog(3) message need not include a terminating
newline character (one will be added if required).
