Hi all, unfortunately the comment does not allow attaching scripts. I have patched the 2 provided scripts to work on Linux (they fail now). Tried with CentOS 7.x. Can you please review and update the current versions (that are since 2012)?
The patched files and more information (also for prerequisites) on https://micharg.blogspot.com/2019/05/patched-nagios-scripts-to-monitor-top-5.html

I tested both of them on CentOS 7.2, the CPU check worked after dos2unix.
But the MEM check needed some more changes.
The script used "machinfo" but this isn't a command in CentOS. So I used "cat /proc/meminfo | grep Memtotal"
I also changed the total free memory, to this command:
# Total memory available
totalmem=`cat /proc/meminfo | grep -i memtotal`
totalmem=`echo $totalmem | awk '{print $2}'`
#totalmem=`echo "$totalmem * 1024" | bc`
#echo "TotalMem=$totalmem"
#Total Free Memory
freemem=`cat /proc/meminfo | grep -i memfree`
freemem=`echo $freemem | awk '{print $2}'`
I also had a problem with "bc", I constantly got a error about the decimal that was included.
But I changed the calculation so it wouldn't get the error anymore:
# Total memory used
usedmem=`echo "$totalmem - $freemem" | bc -l`
#echo "UsedMem=$usedmem"
#Percent Used Mem for Calculation.
percused=`echo $usedmem / $totalmem | bc -l`
#Percent Used Mem
percentused=`echo "scale=0;($percused * 100/1)" | bc -l`
#echo "PercentUsedMem=$percentused"
percentfree=`echo "100 - $percentused" | bc -l`
And I got an integer expression on line 123, so I changed the command a bit.
OUTPUT=";Top 5 Memory Processes(memKB,pname,pid): " ;
for word in $COMMAND; do
i=`expr $i + 1`
j=`expr $j + 1`
if [[ $i -eq 3 ]]; then
i=0;
if [ $j -eq 15 ]; then
OUTPUT="$OUTPUT `echo $word`" ;
else
OUTPUT="$OUTPUT `echo $word, `" ;
fi
else
if [ "$i%3" = "1" ]; then ## It was this: [ $i%3 -eq 1 ] ##
OUTPUT="$OUTPUT `echo $word"KB"`" ;
else
OUTPUT="$OUTPUT `echo $word `" ;
fi
fi
done
After I made this changes it worked fine.

To use this plugin under linux you may need to convert it with dos2unix tool. It comes in windows format.
