Using awk to format an output for nstats - awk

Question

I would like to get a complete hostname with their server up-time using "nstats" command. The script appears to be working ok. I need help with the 1st column with a "complete" hostname and the 7th column (server up-time) printed.
This following command only give me their partial hostnames:
for host in $(cat servers.txt); do nstats $host -H | awk 'BEGIN {IFS="\t"} {$2=$3=$4=$5=$6=$9="" ; print}' ; done
BAD Output: (host-names got cut off after the 12th characters)
linux_server 223 days
linux_server 123 days
windows_serv 23 days
windows_serv 23 days
EXPECTED Output:
linux_server1 223 days
linux_server2 123 days
windows_server1 23 days
windows_server2 123 days
The contents of servers.txt file are as follows:
linux_server1
linux_server2
windows_server1
windows_server2
Output without awk
LINXSERVE10% for host in $(cat servers.txt); do nstats $host -H ; done
linux_server 0.01 47% 22% 56 05:08 20 days 17:21:00
linux_server 0.00 23% 8% 45 05:08 24 days 04:16:46
windows_serv 0.04 72% 30% 58 05:09 318 days 23:32:17
windows_serv 0.00 20% 8% 40 05:09 864 days 12:23:10
windows_serv 0.00 51% 17% 41 05:09 442 days 05:30:14
Note: for host in $(cat servers.txt); do nstats $host -H | awk -v server=$host 'BEGIN {IFS="\t"} {$2=$3=$4=$5=$6=$9="" ; print server }' ; done *** this works ok but it will list only a complete hostname with no server uptime.
Any help you can give would be greatly appreciated.

Do you know you may choose the fields to print in awk?
for host in $(cat servers.txt); do
nstats $host -H |
awk 'BEGIN {IFS="\t"} {print $1,$7,$8}';
done
These will print only three fields you are interested.
The awk code labeled as a "note" is totally useless -- It is equivalent to
for host in $(cat servers.txt); do
echo "$host"
done
UPDATE: after realizing the problem was the nstats command, the awk line command would be
awk -v server="$host" 'BEGIN {IFS="\t"} {print server,$7,$8}';
then the output looked like this (server uptime overwrote the hostnames)
20 daysrver
24 daysrver
318 daysver
864 dayserv
442 dayserv
So I put that server variable at the end, it looked much better and i can extract that and play with it in excel. THANKS SO Much Jdamian!
for host in $(cat servers.txt); do nstats $host -H | awk -v server="$host" 'BEGIN {IFS="\t"} {print $7,$8,server}'; done
20 days linux_server1
24 days linux_server2
318 days windows_server1
864 days windows_server2
442 days windows_server3
