PMDAOPENLOG(3)          Library Functions Manual          PMDAOPENLOG(3)

NAME

       pmdaOpenLog - redirect stderr to a logfile

C SYNOPSIS

       #include <pcp/pmapi.h>
       #include <pcp/pmda.h>

       void pmdaOpenLog(pmdaInterface * dispatch);

       cc ... -lpcp_pmda -lpcp

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).

CAVEAT

       The PMDA must be using PMDA_INTERFACE_2 or later, as specified in
       the call to pmdaDSO(3) or pmdaDaemon(3).

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.

       pmdaGetOpt(3).
