Over the years of owning my own dedicated servers, I often find myself logging into the server just to check the load, the logs, and if there was any downtime. And eventually, I ended up creating a network of servers talking and checking each other, and sending the results (if necessary) to me and logging the rest. It’s always important to keep track of the health of your server, in both uptime, storage space, and load average, here are some great scripts I’ve created and have worked perfectly.
Each of these bash scripts should be copied into a file and run using a cron job every few minutes for optimal use. You’ll want to have these scripts setup on each of your servers, and have them monitor each other for best results. You can set it to send the notification to anywhere you want. Personally, I send it as a text message to my phone, and carbon copy it to my email. This way, I’m always connected with my servers, and I know what’s going on when I need to know, and not after there’s already a problem. If you’re getting too many notifications, try changing the check count(s) or load average limits.
