在下面的循环中,我尝试将两个变量(totalentries 和totalusedbytes)的值重置为零,但从结果中我可以看到它从未发生。因此,每个循环继续添加到前一个循环的运行总数中
# For each grid name, get a list of map indexes for that gridname
for grid in "${gridNames[@]}"
do
totalentries=0
totalusedbytes=0
indexlist=`snmpwalk -v 2c -c splunk $host mapGridName -m $APPLIANCEMIB -OUQs -Ln | grep $grid | sed -n 's/.*mapGridName\.\([0-9]\+\)[^0-9].*/\1/p'`
# Split list into an array
while read -r line; do
indexes+=(`echo $line`)
done <<< "$indexlist"
# Get the stats
for index in "${indexes[@]}"
do
# Entries in Cache
numentries=`snmpget -v 2c -c splunk $host mapNumEntries.$index -m $APPLIANCEMIB -OUQs -Ln | sed -n 's/.*\=[^0-9]\([0-9]\+\).*/\1/p'`
# Used Bytes
usedbytes=`snmpget -v 2c -c splunk $host mapUsedBytes.$index -m $APPLIANCEMIB -OUQs -Ln | sed -n 's/.*\=[^0-9]\([0-9]\+\).*/\1/p'`
if [[ $numentries ]]
then
totalentries=`expr $totalentries + $numentries`
fi
if [[ $usedbytes ]]
then
totalusedbytes=`expr $totalusedbytes + $usedbytes`
fi
done
echo $grid"_totalentries="$totalentries
echo $grid"_totalusedbytes="$totalusedbytes
done
这是输出,循环中的大多数网格什么都没有,但它们得到了前一个循环的总和
A_grid_totalentries=0
A_grid_totalusedbytes=0
B_grid_totalentries=3
B_grid_totalusedbytes=30142
C_totalentries=3
C_totalusedbytes=30142
D_grid_totalentries=3
D_grid_totalusedbytes=30142
E_grid_totalentries=3
E_grid_totalusedbytes=30142
F_totalentries=3
F_totalusedbytes=30142
G_grid_totalentries=92
G_grid_totalusedbytes=1054348
H_grid_totalentries=96
H_grid_totalusedbytes=1114431
I_grid_totalentries=96
I_grid_totalusedbytes=1114431
答案1
问题是您不断添加到索引数组,并且从不重置它。当您将这些变量重置为零时,将数组设置为空:
totalentries=0
totalusedbytes=0
indexes=()
或者,以不同的方式填充数组:
mapfile -t indexes <<< "$indexlist"
