NAME

       pmcd_wait - wait for PMCD to accept client connections

SYNOPSIS

       $PCP_BINADM_DIR/pmcd_wait [-v] [-h host] [-t timeout]

DESCRIPTION

       pmcd_wait  waits  for  the  Performance  Metrics Collector Daemon (PMCD) to be running and
       accepting client connections.

       Unless directed to another host by the -h option, pmcd_wait will try to contact pmcd(1) on
       the local host.

       pmcd_wait  will timeout and abandon the attempt to connect to pmcd after 60 seconds.  This
       default timeout interval may be changed using the -t option, where the  interval  argument
       follows  the  syntax  described in PCPIntro(1) and in the simplest form may be an unsigned
       integer (the implied units in this case are seconds).

       On successful connection to pmcd an exit status of zero is returned.

       If an error or timeout occurs, then a non-zero exit status is returned as described below.

OPTIONS

       The available command line options are:

       -h host, --host=host
            Connect pmcd(1) on host, rather than the one on the default localhost.

       -t timeout, --interval=timeout
            Timeout after timeout seconds if not connected.  The  default  timeout  value  is  60
            seconds.

       -v, --verbose
            This  option  turns  the  verbose  mode  on.  With the verbose mode off (which is the
            default), no output will be generated.  With verbose mode on, error messages will  be
            output on stderr.

DIAGNOSTICS

       Error messages will be output to stderr only if the verbose mode is on.

       The following exit status codes are returned:

       0      pmcd_wait was able to successfully connect to pmcd within the timeout period.

       1      A usage error occurred, use -v for more details.

       2      No  connection  was  made  in  the  timeout  interval.  This will happen if pmcd is
              running but takes too long to complete the client connection, or  if  pmcd  is  not
              running  and  all connection attempts in the timeout interval failed with the error
              ECONNREFUSED.

       3      A UNIX error occurred, use -v for more details.

       4      A PCP error occurred, use -v for more details.

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).
