Hello venkitesh,

Welcome to forums, could you please try following and let me know if this helps.
Code:
awk '{TOT=$2+0;gsub(/[[:digit:]]|\./,X,$2);USED=$3+0;gsub(/[[:digit:]]|\./,X,$3);if(($2 ~ /GB/ || $2 ~ /TB/)&& TOT>=USED){VAL=USED/TOT * 100};if($2 ~ /TB/ && $3 ~ /GB/ && TOT>=USED){VAL=USED/(TOT * 1024) * 100};if(VAL>20){print $1" filesystem has more disk space used than threshold."};VAL=""}'  Input_file

Output will be as follows.
Code:
/test/test1 filesystem has more disk space used than threshold.

So in above code I have put 20 as threshold, you could set it as per your requirement. I hope this helps(It only handles filesystem capacity in either TBs and GBs).
EDIT: Adding a non-one liner form of solution now too.
Code:
awk '{
        TOT=$2+0;
        gsub(/[[:digit:]]|\./,X,$2);
        USED=$3+0;
        gsub(/[[:digit:]]|\./,X,$3);
        if(($2 ~ /GB/ || $2 ~ /TB/) && TOT>=USED){
                                        VAL=USED/TOT * 100
                                  };
        if($2 ~ /TB/ && $3 ~ /GB/ && TOT>=USED){
                                                VAL=USED/(TOT * 1024) * 100
                                               };
        if(VAL>20){
                        print $1" filesystem has more disk space used than threshold."
                  };
        VAL=""
     }
   '   Input_file

Thanks,
R. Singh
