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_PROTOCOL_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.
