Hi, I am looking for something that will give me notice via email of a down server or other fault such as overload. Can you please recommend something Thanks.

If you have a separate server to run your check script on, something like this would do a simple Ping test to see if the server is alive: Cron this script.

#!/bin/bash SERVERIP=IP_Address NOTIFYEMAIL=test@example.com

ping -c 3 $SERVERIP > /dev/null 2>&1 if [ $? -ne 0 ] then

Use your favorite mailer here:

mailx -s “Server $SERVERIP is down” -t “$NOTIFYEMAIL” < /dev/null fi

****Hi, Thank you for your response. I realize that that i would have to use another server to do the checking if the server is down. I was just wondering if DigitalOcean had a ready made script or API to get it done.

hmm…not sure a server that is down can send you an email…or do anything for that matter.

however, a server can certainly send you a notification if a service has stopped or crashed (like mysql or apache or such)

You could possibly have a different droplet that checks on other droplets, and then sends you an email. Same idea: you would write a script that pings your other droplet, or attempts to ssh into it, or whatever, and then put that script on a cronjob for every 10 minutes, or hour or whatever.

Do you have server that goes down a lot?

First off - thanks for sharing @amol - am curious about this, sooo:

**Question(s) **

  • Am new to this. Is such a script completely safe? Does one need to harden the server or network in some way when croning something like this?

  • Can frequent pinging affect server load / bandwidth and thus impact the server’s speed/performance negatively?

  • Am not a code wiz - just a dude. How often does this script ping? (I know, sry - can’t even deduct from the code - duh!)

Anebody by chance feel like doing DigitalO writeup/setup tut for this using SSH or what the heck it’s called nowadays? Something set-by-step’ish for dummies like me - preferably something with real-life config example values… or perhaps someone can throw a link if similar has already been made available (?)

Don’t hope you mind the q’s/input. Appreciate it! :-)
