Description of problem:


I thought about experimenting with pmdabash & network (because pipe does not seem to work correctly, https://bugzilla.redhat.com/show_bug.cgi?id=1216085), so using socket instead of pipe:


[root@ibm-z10-06 bash]# ./Install 
You will need to choose an appropriate configuration for installation of
the "bash" Performance Metrics Domain Agent (PMDA).

  collector     collect performance statistics on this system
  monitor       allow this system to monitor local and/or remote systems
  both          collector and monitor configuration for this system

Please enter c(ollector) or m(onitor) or b(oth) [b] 
Install bash as a daemon or dso agent? [daemon] 
PMCD should communicate with the bash daemon via a pipe or a socket? [pipe] socket

Specific command line used to start pmdabash was "/var/lib/pcp/pmdas/bash/pmdabash.orig -d 112 -i 2082", however "-i" option is not supported by pmdabash, as documented by stracing pmdabash:

53549      0.000026 write(0, "pmdabash.orig: invalid option -- 'i'\nUsage: pmdabash.orig [options]\n\nOptions:\n  -d NUM, --domain=NUM  use domain (numeric) for metrics domain of PMDA\n  -l FILE, --log=FILE   write log to FILE rather than using default log name\n  -m SIZE, --memory=SIZE\n                        maximum memory used per logfile (default 2MB)\n  -s DELTA, --interval=DELTA\n                        default delay between iterations (default 1 sec)\n  -U USER, --username=USER\n                        run the PMDA using the named user account\n  -?, --help            show this usage message and exit\n", 574) = 574


Version-Release number of selected component (if applicable):

pcp-3.9.10-8
This is also true for RHEL6.7 build, pcp-3.10.3-2, though bash version included in RHEL6.7 is not supported by pmcdbash (4.1.2-33 is too low), therefore I'm focusing mostly on RHEL7.
