Sai,
You're trying to start the primary logger here. What is the name of the
host pmlogger is running on?
If it xcat20mn then your pmlogger control file is OK, but there is a
problem with pmcd on this host ... please send output from
$ pcp
$ pcp -h xcat20mn
$ cat /var/log/pcp/pmcd/pmcd.log
If it not, then you need to amend your control file ... change the first
y to n and then run (and send the output from)
# /usr/lib/pcp/bin/pmlogger_check -V
Also (since I suspect you may be trying to start more than one pmlogger
for the same host), it would help to see output from
1. ps -ef | grep pmlogger
2. pminfo -f pmcd.pmlogger
3. and all your pmlogger control file
