Thanks for the details.
Do you have DNS setup on the mn for the nodes?
run host <nodename>
Does it give correct ip address?

Hi ling,
It is there and running.
Starting it manually gives:

Hi Bert,
Does the cluster have service node involved? After you run monstart,
the cronjob /opt/xcat/sbin/pcp_collect is supposed to be run on the mn and
the sn.
Please check if there are cron jobs running on the mn and the sn? If there
is no service node, then just check on the mn.
crontab -l
What does it return?
You can also run /opt/xcat/sbin/pcp_collect manually, (you can uncomment
some of the print statement), to see what might be wrong.

Hello Ling,
It is the standard entry:
# cat pcpmon.config
mem.physmem
mem.util.free
mem.util.swapFree
filesys.used
proc.memory.size
disk.dev.total
We are running:
# xdsh -V
Version 2.5.1 (svn r8304, built Thu Dec 2 14:31:00 EST 2010)
I tried the rcm as well with the same effect.

What is the file $::XCATROOT/lib/perl/xCAT_monitoring/pcp/pcpmon.config
looks like?
What version of xCAT are you using? (xdsh -V)

________________________________________
Hi,
I am trying to set up a monitoring with xcat and pcp.
I got pcp-3.5.8-1 and installed it on the headnode and some computenodes.
nodetype is osi.
monadd pcpmon
monstart pcpmon -r
...
# monls pcpmon
pcpmon monitored node-status-monitored
tabdump monsetting is empty
tabdump performance is empty
monshow pcpmon nodeXY is empty
The daemons are running and I can query the remote machine with pminfo.
What am I missing?
Best regards,
Bert
