PMCD_WAIT(1) General Commands Manual 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
configuration 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 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.
