PCP Process PMDA question

[Chandana De Silva <chandana@xxxxxxxxxxxxx>]

All,

I am running PCP 3.10 on two CentOS 5.8 hosts.

The PMCD config shows the process PMDA as ;

process	71	pipe	binary 		/var/lib/pcp/pmdas/process/pmdaprocess -d 71

However, the file /var/lib/pcp/pmdas/process/pmdaprocess does not exist.

But both machines show that the the PMDA is running

$ pcp

Performance Co-Pilot configuration on gwdb02.prod.mel.au.m4u.com.au:


 platform: Linux gwdb02.prod.mel.au.m4u.com.au 2.6.18-308.24.1.el5 #1 SMP Tue Dec 4 17:43:34 EST 2012 x86_64

     pmda: pmcd linux mysql mmv process[4]

Hoever, only one machines shows the processes when queried:

$ pminfo -f process.running

process.running

    inst [0 or "sshd"] value 3

    inst [1 or "crond"] value 2

    inst [2 or "mysqld"] value 2

The other machine gives an error, and there is no process.log file 

$ pcp

[m4u-chandana@xxxxxxxxxxxxxxx pmcd]$ pminfo -f process.running

process.running: pmLookupDesc: No PMCD agent for domain of request

The pmcd.conf on this machine shows an error:

pmcd: error starting /var/lib/pcp/pmdas/process/pmdaprocess: No such file or directory

pmcd: unexpected end-of-file at initial exchange with process PMDA


Help, please

Thanks
