I run a command to fetch server uptime as below

[root@localhosts ~]# printf "`uname -n`  `uptime| awk -F " " {'print $3,$4'}`\n"  
localhosts  75 days,

Now when I run same command from another hosts to same above linux server "localhosts" to get same output, I get error

[root@master /]# ssh localhosts 'printf "`uname -n`  `uptime| awk -F " " {'print $3,$4'}`\n"'  
awk: cmd. line:1: {print  
awk: cmd. line:1:       ^ unexpected newline or end of string  

Do you know better way to run the command from another hosts to get similar output from the remote hosts as well?

The issue is that you had nested single quotes. That does not work well.
