cpu.sh not running with the interval

In my app

opt/splunk/etc/apps/cust_unix/local/inputs.conf I have these lines below, and I'm assume it will run every 5 sec. Seems like it'll run whenever it feel like, and no time pattern. How to debug this?

inputs.conf:
[script://./bin/cpu.sh]
sourcetype = cpu
source = cpu
interval = 5
index = os
disabled = 0

cpu.sh:
. dirname $0/common.sh

HEADER='CPU pctUser pctNice pctSystem pctIowait pctIdle'
HEADERIZE="BEGIN {print \"$HEADER\"}"
PRINTF='{printf "%-3s %9s %9s %9s %9s %9s\n", cpu, pctUser, pctNice, pctSystem, pctIowait, pctIdle}'

if [ "x$KERNEL" = "xLinux" ] ; then
queryHaveCommand sar
FOUND_SAR=$?
queryHaveCommand mpstat
FOUND_MPSTAT=$?
if [ $FOUND_SAR -eq 0 ] ; then
CMD='sar -P ALL 1 1'
FORMAT='{cpu=$(NF-6); pctUser=$(NF-5); pctNice=$(NF-4); pctSystem=$(NF-3); pctIowait=$(NF-2); pctIdle=$NF}'
elif [ $FOUND_MPSTAT -eq 0 ] ; then
CMD='mpstat -P ALL 1 1'
FORMAT='{cpu=$(NF-9); pctUser=$(NF-8); pctNice=$(NF-7); pctSystem=$(NF-6); pctIowait=$(NF-5); pctIdle=$(NF-1)}'
else
failLackMultipleCommands sar mpstat
fi
FILTER='/Average|Linux|^$|%/ {next} (NR==1) {next}'
elif [ "x$KERNEL" = "xSunOS" ] ; then
if [ $SOLARIS_8 -o $SOLARIS_9 ] ; then
CMD='mpstat -p 1 2'
else
CMD='mpstat -q -p 1 2'
fi
assertHaveCommand $CMD
FILTER='(NR<=2) {next} ($1 >= "0") {inBlock=1} (!inBlock) {next}'
FORMAT='{cpu=$1; pctUser=$(NF-4); pctNice="?"; pctSystem=$(NF-3); pctIowait=$(NF-2); pctIdle=$(NF-1)}'
elif [ "x$KERNEL" = "xDarwin" ] ; then
CMD='sar -u 1'
assertHaveCommand $CMD
FILTER='($0 !~ "Average") {next}'
FORMAT='{cpu="all"; pctUser=$2; pctNice=$3; pctSystem=$4; pctIdle=$5; pctIowait="?"}'
elif [ "x$KERNEL" = "xFreeBSD" ] ; then
CMD='iostat -C -c 2'
assertHaveCommand $CMD
FILTER='(NR<4) {next}'
FORMAT='{cpu="all"; pctUser=$(NF-4); pctNice=$(NF-3); pctSystem=$(NF-2); pctIdle=$NF; pctIowait="?"}'
fi

$CMD | tee $TEE_DEST | $AWK "$HEADERIZE $FILTER $FORMAT $PRINTF" header="$HEADER"
echo "Cmd = [$CMD]; | $AWK '$HEADERIZE $FILTER $FORMAT $PRINTF' header=\"$HEADER\"" >> $TEE_DEST

interval is generally in seconds unless you specify in crontab format:
interval = [|]
* How often to execute the specified command (in seconds), or a valid cron schedule.
* NOTE: when a cron schedule is specified, the script is not executed on start-up.
* Defaults to 60 seconds.

I'm not sure how the passAuth actually functions, but I would expect (since I'm not seeing additional information for configuring sudo) that it can't elevate it's priviliges, but only drop from root to another user. You could wrap it in another script to use sudo.
