NAME

       pmcd_wait - wait for PMCD to accept client connections

SYNOPSIS

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

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.

       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.

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).

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.
