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).
SEE ALSOPCPIntro(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.
