NAME

6       pmcd_wait - wait for PMCD to accept client connections
7

SYNOPSIS

9       $PCP_BINADM_DIR/pmcd_wait [-h host] [-t interval] [-v]
10

DESCRIPTION

12       pmcd_wait  waits for the Performance Metrics Collector Daemon (PMCD) to
13       be running and accepting client connections.
14
15       Unless directed to another host by the -h option, pmcd_wait will try to
16       contact pmcd(1) on the local host.
17
18       pmcd_wait will timeout and abandon the attempt to connect to pmcd after
19       60 seconds.  This default timeout interval may be changed using the  -t
20       option,  where  the  interval  argument follows the syntax described in
21       PCPIntro(1) and in the simplest form may be an  unsigned  integer  (the
22       implied units in this case are seconds).
23
24       On successful connection to pmcd an exit status of zero is returned.
25
26       If  an error or timeout occurs, then a non-zero exit status is returned
27       as described below.
28
29       The other options are as follows:
30
31       -v     This option turns the verbose mode on.  With  the  verbose  mode
32              off  (which  is the default), no output will be generated.  With
33              verbose mode on, error messages will be output on stderr.
34

PCP ENVIRONMENT

36       Environment variables with the prefix PCP_ are used to parameterize the
37       file  and  directory names used by PCP.  On each installation, the file
38       /etc/pcp.conf contains the  local  values  for  these  variables.   The
39       $PCP_CONF  variable may be used to specify an alternative configuration
40       file, as described in pcp.conf(5).

DIAGNOSTICS

46       Error messages will be output to stderr only if the verbose mode is on.
47
48       The following exit status codes are returned:
49
50       0      pmcd_wait was able to successfully connect to  pmcd  within  the
51              timeout period.
52
53       1      A usage error occurred, use -v for more details.
54
55       2      No  connection was made in the timeout interval.  This will hap‐
56              pen if pmcd is running but takes too long to complete the client
57              connection,  or  if  pmcd  is  not  running  and  all connection
58              attempts in the timeout interval failed with the error  ECONNRE‐
59              FUSED.
60
61       3      A UNIX error occurred, use -v for more details.
62
63       4      A PCP error occurred, use -v for more details.
