What are the options for a simple monitoring system:

  • Operating System to install on: Linux
  • Only need to ping device.
  • Send alerts if devices are not responding to ping.
  • Simple to add devices - such as adding IP address in a text file with a description.
  • Alerts to be sent on email when hosts are not responding.
  • Will be monitoring 25-75 devices.
  • Don't need any web interface or anything else than ping, but if it has such, it is not a problem.
  • A script scheduled with Cron would be ok. But the best would be something with a bit of intelligence such as notify when host is back up after a down.
  • Free.

Note: A script would be ok.

I used to use the following script, it does everything you asked for. You just need to add a cronjob entry so that it gets executed regularly:

# add ip / hostname separated by while space
HOSTS='cat server_list.txt'

# no ping request

# email report when
SUBJECT="Ping failed"
EMAILID="[email protected]"
for myHost in $HOSTS
  count=$(ping -c $COUNT $myHost | grep 'received' | awk -F',' '{ print $2 }' | awk '{ print $1 }')
  if [ $count -eq 0 ]; then
    # 100% failed
    echo "Host : $myHost is down (ping failed) at $(date)" | mail -s "$SUBJECT" $EMAILID
  • I was going to write one, but it seems like you beat me! +1
