Script awk for report size all vgs.

[Claudemir Franco]

Hi guys,

I have a script report size all vgs, but the script is not correct fully. This is my script.

awk 'BEGIN { num_lv=0}
/Cur LV/ {num=$NF}
/PE Size/ {meg=$NF}
/Alloc PE/ {pe=$NF}

/LV Name/ {lvname[++num_lv]=$NF}
/LV Size/ {lvname[num_lv,"size"]=$NF}

END {print "Total Mb used= ",vg=meg*pe
for (i=1;i<=num_lv;i++) {
pct=(lvname[i,"size"]/vg*100)
tot=tot+pct
printf
("%s%s%s%6.2f%10s","volume\t",lvname[i],"\tis",pct,"percent\n")}
printf "%26s%6.2f\n","total ",tot
print "\n"
for (i=1;i<=num_lv;i++) {
pct=(lvname[i,"size"]/vg*100)
pct=(int(pct))
printf ("%s\t",lvname[i])
for (n=1;n<=pct;n++) printf ("%c", "*")
print""}}


When I execute this, show me the error:
------------------------------------------
syntax error The source line is 1.
The error context is
awk >>> ' <<<
awk: Quitting
The source line is 1.
------------------------------------------

Whats wrong?

Thanks..

Hi:

You have an unpaired sigle quote beginning on line-1:

'BEGIN

Change line-1 to be two lines to read:

#!/usr/bin/awk
BEGIN { num_lv=0}

Regards!

Thanks James, your tips really functioned.

But I have other error in line 16:

root@hpdev01:/root/scripts:>awk -f report_size_vg
syntax error The source line is 16.
The error context is
>>> ("%s%s%s%6.2f%10s","volume\t",lvname[i],"\tis",pct,"percent\n")} <<<
awk: The statement cannot be correctly parsed.
The source line is 16.
syntax error The source line is 24.

Note: This scripts i get in the my book "POSIX Shell Programming", I'm need this script for monitoring environment.

Thanks is advance.

Hi (again):

Awk is fussy! At line-16, join the 'printf' with its arguments:

printf("%s%s%s%6.2f%10s","volume\t",lvname[i],"\tis",pct,"percent\n")}

Regards!

Hi Claudemir:

By the way, I should have specified the interpreter line as:

#!/usr/bin/awk -f

Regards!

hi, JRF....

Very, very very thanks a lot of.... :o)


it is functioning.

There is one floating around the ITRC - so you didn't have to reinvent the wheel so to speak - called vgttl:

# cat /usr/local/bin/vgttl
#!/bin/sh
/usr/local/bin/bdfmegs|grep vg |tr -s " " " "|cut -d" " -f 1-4|sort|
awk 'BEGIN {
prev="";
totals[0]=0;
totals[1]=0;
totals[2]=0;
gtotals[0]=0;
gtotals[1]=0;
gtotals[2]=0;
printf("%8s %14s %14s %14s\n","VG","Size(MB)","In use","Available");
}
{split($1,curr,"/");
if (prev!="" && prev!=curr[3])
{printf("%8s %14d %14d %14d\n",prev,totals[0],totals[1],totals[2]);
gtotals[0]+=totals[0];
gtotals[1]+=totals[1];
gtotals[2]+=totals[2];
totals[0]=0;
totals[1]=0;
totals[2]=0;
}
prev=curr[3];
totals[0]+=$2;
totals[1]+=$3;
totals[2]+=$4;
}
END {
gtotals[0]+=totals[0];
gtotals[1]+=totals[1];
gtotals[2]+=totals[2];
printf("%8s %14d %14d %14d\n",prev,totals[0],totals[1],totals[2]);
printf("%8s %14s %14s %14s\n","----","--------------","--------------","--------------");
printf("%8s %14d %14d %14d\n","Totl",gtotals[0],gtotals[1],gtotals[2]);
}'


And the bdfmegs script:
# cat /usr/local/bin/bdfmegs
#!/usr/bin/sh
#
# Ver 3.1 - Trap fsadm errors and change return code. Allow -vl
# or -lv combinations.
# Ver 3.0 - Rewrote using temp files to speed up code about 10:1
# Added -l option and ? or -? help
# Ver 2.1 - Added vxfs filesystem layout verrsion (2,3,4,etc)
# Added non-root check for -v option fsadm needs root
# permission for fsadm to read lvols directly.
# Ver 2.0 - Change Blks to blk/frag size and add largefile status
# Made: FSTYPE blk/frag and largefile optional with -v
# to reduce the width of the line
#
# Ver 1.2 - Expanded filesystem type to handle autofs
# Ver 1.1 - Added blocksize column for filesystem blocks
# Ver 1.0 - Original

# Usage: bdfmegs [ -v ] [ -l ] [ -? | ? ]
