it is printing uname -n instead of printing the output of the command

You could use:

{ system( "uname -n" ) }

Without print. The stdout will go to your terminal.

If you need to manipulate that information further,
you could save it in an awk variable:

{ "uname -n" | getline sn }

The machine name will be stored in the sn variable.

awk '{if ($1 == "State:" && $2 == "Okay") {"uname -n"|getline sn; print $sn}}'

tried this it is not working.

awk '{if ($1 == "State:" && $2 == "Okay") {system( "uname -n" )}}'

this also is not working.

I work in KSH

In the first case it should be:

print sn

Note that there is no dollar sign.

If the expression $1 == "State:" && $2 == "Okay" evaluates to true and the uname command is accessible and executable, the second one should work.

5 
#metastat -t|grep State|awk '{if ($1 == "State:" && $2 == "Okay") {"uname -n"|getline sn; print sn}}'
awk: syntax error near line 1
awk: illegal statement near line 1
 # metastat -t|grep State |awk '{if ($1 == "State:" && $2 == "Okay") {system( "uname -n" )}}'
# metastat -t|grep State |awk '{if ($1 == "State:" && $2 == "Okay"){print "Hi"}}'
Hi

Hi
Hi
# metastat -t|grep State |awk '{if ($1 == "State:" && $2 == "Okay"){print "Hi"}}'

yes uname works .

Could you post an example output from memstat -t ?

You should use nawk or /usr/xpg4/bin/awk on Solaris.

# memstat -t
ksh: memstat: not found
XXXXXX:/ # uname -n
XXXXXX

I think radoulov meant you to post the output from the command:

metastat -t

Typed from the command line as user root with no pipes or other filtering.

Yes,
of course.
If the OP posts the output of memstat,
we could provide a more concise solution.
