Ling,
thx a lot! I will update xCAT and let you know if it didn't solve the
problem.

Hi Gilad,
What version of xCAT are you using? (xdsh -V)
You did everything right. The problem is in the code. One of the
user on this list fount it and found a cure. We have checked the code in
the latest xCAT 2.6.10 and xCAT 2.7. You can either download the latest
build, or change the code manually.
/opt/xcat/lib/perl/xCAT_plugin/nodestat.pm
change
$newappstatus =~ s/(\w+)\=(\w+)//g;
to
$newappstatus =~ s/(\w+)\=(\w+)//;
Change it on both mn and service nodes, restart the xcatd ( service xcatd
restart).
Performance wise, I see no difference between letting xcatmon handle it or
using script to handle the output of nodestat. Remember you can change
the "ping-interval".
Hope it helps,
Ling

Subject: [xcat-user] xcatmon question
Hello,
I'm trying to use xCAT to monitor LSF status on the nodes using xcatmon. i
followed the instruction in the monitoring document, however, i don't get
any indication to the apps status and monitoring, although the defauls
sshd and xend monitoring works as expected. I tried both the port method
and the dcmd method, neither worked.
on the other hand, nodestat -m works as expected.
[root@lsfsr ~]# tabdump monsetting
#name,key,value,comments,disable
"xcatmon","apps","lsf,lsf1",,
"xcatmon","lsf1","dcmd=/root/lsfcheck",,
"xcatmon","lsf","port=6878,group=blades",,
"xcatmon","ping-interval","1",,
[root@lsfsr ~]# tabdump nodelist
#node,groups,status,statustime,appstatus,appstatustime,primarysn,hidden,comments,disable
"lsfcl1","all,blades","ping","02-21-2012
20:08:02",",xend=down,sshd=up","02-21-2012 23:07:03",,,,
"lsfcl2","all,blades","ping","02-21-2012
20:08:02",",xend=down,sshd=up","02-21-2012 23:07:03",,,,
"lsfcl3","all,blades","ping","02-21-2012
20:08:02",",xend=down,sshd=up","02-21-2012 23:07:03",,,,
"amm","mm",,,,,,,,
[root@lsfsr ~]# monls
xcatmon monitored node-status-monitored
[root@lsfsr ~]# crontab -l
*/1 * * * * XCATROOT=/opt/xcat
PATH=/sbin:/usr/sbin:/bin:/usr/bin:/opt/xcat/bin:/opt/xcat/sbin XCATCFG=''
/opt/xcat/bin/nodestat all -m -u -q
[root@lsfsr ~]# nodestat blades -m
lsfcl1: sshd,lsf1=down
lsfcl2: lsf,sshd,lsf1=up
lsfcl3: lsf,sshd,lsf1=up
/root/lsfcheck is a script the returns 'up' or 'down', depends on the lsf
service status.
1. What am i missing? why the nodelist table is not updated?
2. Performance wise - what will be better - to parse the nodestat command
and run a script or using the xcat notification infrastructure?
thx in advance!
