Collecting PowerVP system level data from the AIX command line.

cggibbo Tags: jar aix line gibson chris java powervp command 3,799 Views

It’s possible to collect PowerVP system level agent data from the AIX command line.

You can collect this data by running Java and specifying the powervp.jar file, as shown below. You need to specify the hostname, username and password for the host where the system level agent resides. In the following example the hostname/IP address is 10.1.1.99 and the username/password is root and mypass1. I found the PowerVP JAR file in the default PowerVP install directory, which (on AIX) is usually /IBM/PowerVP/PowerVP_GUI_Installation/PowerVP/.

This will connect you to the PowerVP system level agent on the specified host. It will continue to run and collect data until you enter ‘exit’ at the prompt.

This got me thinking. Perhaps I could write a small script to wrap all this up and then schedule it from cron to collect data on a regular basis?

I wrote the beginnings of a basic expect script (shown below) which would allow me to run the script for a specified amount of time (in seconds) and pass the hostname, username and password from the AIX command line. I guess this would work fine from Linux as well?

[root@gibbo][PowerVP]/IBM/PowerVP/PowerVP_Installation/PowerVP_GUI_Installation # cat cg_powervp

send "exit\r"

I was attempting to configure a new installation of lpar2rrd (version 2.65) for a customer today when I encountered the following error during the initial load of data from the HMC:

lpar2rrd@nim [/home/lpar2rrd/lpar2rrd]$ ./load.sh

Wed 23 Nov 12:04:09 2011 : hmc01 : An error occured in lpar2rrd.pl, check ./error.log and output of load.sh

We were able to get this working by hacking the lpar2rrd.pl script.

The following code:

if ( $loadhours <= 0 || $loadmins <= 0) { # workaround as this sometimes is negative , need to check it out ...

my $t1 = localtime($$last_rec);

my $t2 = localtime($t);

print STDERR "$act_time: time issue 1 : $host:$managedname $loadhours $loadmins \n";

print STDERR " Last saved record (HMC lslparutil time) : $$last_rec ; HMC time : $t \n";

print "$act_time: time issue 1 : $host:$managedname $loadhours $loadmins \n" if $DEBUG ;

print " Last saved record (HMC lslparutil time) : $$last_rec ; HMC time : $t \n" if $DEBUG ;

$loadhours = 3;

$loadmins = 140;

}

Was changed to:

$loadmins = 140;

if ( $loadhours <= 0 || $loadmins <= 0) { # workaround as this sometimes is negative , need to check it out ...

my $t1 = localtime($$last_rec);

my $t2 = localtime($t);

print STDERR "$act_time: time issue 1 : $host:$managedname $loadhours $loadmins \n";

print STDERR " Last saved record (HMC lslparutil time) : $$last_rec ; HMC time : $t \n";

print "$act_time: time issue 1 : $host:$managedname $loadhours $loadmins \n" if $DEBUG ;

print " Last saved record (HMC lslparutil time) : $$last_rec ; HMC time : $t \n" if $DEBUG ;

$loadhours = 3;

}

The initial load then ran successfully.

Then we changed the code back to its previous configuration:

if ( $loadhours <= 0 || $loadmins <= 0) { # workaround as this sometimes is negative , need to check it out ...

my $t1 = localtime($$last_rec);

my $t2 = localtime($t);

print STDERR "$act_time: time issue 1 : $host:$managedname $loadhours $loadmins \n";

print STDERR " Last saved record (HMC lslparutil time) : $$last_rec ; HMC time : $t \n";

print "$act_time: time issue 1 : $host:$managedname $loadhours $loadmins \n" if $DEBUG ;

print " Last saved record (HMC lslparutil time) : $$last_rec ; HMC time : $t \n" if $DEBUG ;

$loadhours = 3;

$loadmins = 140;

}

After which, all subsequent loads worked as expected! Fortunately my colleague, Nathan Edwards, had already hit this bug a while ago and was able to help me. Thanks again Nathan!

According to Pavel Hampel (lpar2rrd developer), the next version of lpar2rrd (2.66) will fix this issue.
