PMCD_WAIT(1)									     PMCD_WAIT(1)

       pmcd_wait - wait for PMCD to accept client connections

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

       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.

       The other options are as follows:

       -v     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.

       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 config-
       uration file, as described in pcp.conf(5).

       PCPIntro(1), pmcd(1), pcp.conf(5) and pcp.env(5).

       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 run-
	      ning but takes too long to complete the client connection, or if pmcd is	not  run-
	      ning  and  all  connection  attempts  in the timeout interval failed with the error

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

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