Can anyone recommend a good package for pinging
other devices and
sending an email/alert when they go down? I'm
aware of all kinds of
more complex things with GUIs and a zillion other
bells and whistles
we aren't looking for, but we just want a simple
tool (could be
daemon or something run from cron) that runs
every 1 - 5 minutes and
alerts us when stuff disappears. Would need some
basic logic like
only sending one email/alert when something goes
down (vs sending an
email every 1-5 minutes until it comes back up).
:-) We need to
avoid a requirement for an X-windows GUI, but a
web-GUI would
probably be fine (a GUI-less command-line thing
would probably be best).
Bash. Here is what I use for monitoring my website
#!/bin/bash
URL="http://www.911networks.com"
EMAIL="artsi@fartsi.com"
lynx -dump "$URL" > /dev/null
if [ $? -ne 0 ]; then
echo "`date "+%F %T"` - $URL is down" | mail
-s "$URL is down" $EMAIL
fi
Watch for the wraps and make it executable [chmod
7xx]
This is the sort of thing I was going to suggest.
You could go 1 better
& have it resubmit itself periodically w/ at(1).
Maybe get it to do some
argument parsing so you could pass in the URL,
EMAIL, then invoke plural
instances for however many things you want to
monitor ....

My question is wouldnt this keep on sending emails all
the time ping keeps on seeing it is down. I thought
one of the requirements was once for each occurance? I
probably am reading this wrong...
