Re: PCP - pmlogger command

[Sai p Seshasayee <sseshas@xxxxxxxxxx>]

Ken/Nathan,

I want the pmlogger to work only for
1 min (because I am planning to set that as a cron job and schedule it)
and hence I want to use "-T1min".
Regarding the removal of the archiving
name, Ken, you are spot on: I removed the "sai_logger" archive
name and this time I did not get any errors!
I was able to see the process running
and it was generating a file named "20080902.20.17". But here
is where the problem comes again : I did a search for the file "20080902.20.17"
but I was not able to find it. Where will the archive be stored and how
can I replay it using "kmchart -a " command?

I am also planning to use "pmstat"
command on multiple hosts to capture some information and store it in a
database. The o/p comes like this:

[root@xcat20mn xCAT_monitoring]# pmstat
-h cu03sv -hxcat20mn -s1 -t0.1
@ Tue Sep  2 16:26:18 2008
node    loadavg    
          memory      swap  
     io    system        
cpu
          1
min   swpd   buff  cache   pi   po   bi  
bo   in   cs  us  sy  id
cu03sv     0.00    
 0  79068   987m    0    0    0
   0  199  199   0   0 100
xcat20m    0.04    
 0  1717m  3000m    0    0    0
   0 1109  309   0   0 100

But I want the heading to suppressed
i.e the o/p should only be:

cu03sv     0.00    
 0  79068   987m    0    0    0
   0  199  199   0   0 100
xcat20m    0.04    
 0  1717m  3000m    0    0    0
   0 1109  309   0   0 100

I also want it to appear with a delimiter.
Is it possible ? You have been very helpful and I trust this question should
be a piece of cake for you !

Nathan beat me to it.

But the other "odd" thing is the sai_logger at the end of the
pmlogger
control line.

My guess is this was an attempt at naming the archive, but
pmlogger_check generates the archive name automagically (it is a date
and time stamp) ... so I think that explains the usage message, the lack
of a pmlogger.log file, no archive, etc.

If I use the same control line, I get the same error!

So
1. change the -T1min to -t1min (or drop it entirely and move the logging
intervals into the pmlogger config file where you can choose appropriate
and possibly different intervals per group of metrics)

2. drop the sai_logger at the end of the control line
