pmdaopenlog(3)

NAME

   pmdaOpenLog - redirect stderr to a logfile

C SYNOPSIS

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