Monit: Home server system load monitoring (CPU, RAM, Swap)

How To Use Monit Hardware Monitor

To continue with our complete Monit setup guide, we will show you how to use Monit to keep your server system load in check, in CPU, RAM and Swap. If the resource usage is high on any of them, Monit is capable of sending you an email alert. This email alert can get to you wherever you are (for example, if you are at work, you can be notified of the issue and fix it when you get home). The conditions for which an alert is sent are fully customizable and you can tweak them in order to get the best experience.

Monit: Server hard drive storage monitoring (HDD space)

Monit Config Examples Hdd StorageHDD space is an important parameter of home servers, because that's where our files are stored and determines how many we can keep. With this Monit setup guide for HDD monitoring, you will learn to determine what partitions need to be kept in check, as well as knowing how full any of these partitions are at any given time. You will learn how to test and reload Monit with Monit config examples that will ultimately show available disk and partition space via the Monit web interface. A neat addition to any home server!

Monit: Motherboard temperature monitoring

How To Configure Monit Motherboard MonitorWith this Monit setup guide you will learn how to configure Monit in order to send you alerts whenever the motherboard temperature of your home server is high. This will allow you to take corrective actions and maintain adequate cooling on your device. Monit is able to send you email alerts if the motherboard temperature goes above a certain threshold. Of course, it goes without saying, that in order for Monit to be able to work properly in this case, your motherboard needs to have accurate and functional temperature sensors.

Monit: Processor or CPU temperature monitoring

Monit Tutorial Example Cpu TemperatureAnother critical part of your server that should be always monitored and in top notch condition is the CPU, also known as Processor. These are often expensive. Furthermore, since home servers are most of the time designed to be quiet, cooling for the processor is often passive, which means there are no fans or moving parts, and it might be easy for the CPU to overheat in these cases. Monit is of course able to send email alerts if the CPU temperature is higher than a user-defined threshold, and you will learn how to configure this with this Monit setup guide.

Monit: Monitor Hard drive SMART health and temperature

For these cases you can configure certain intervals and number of restarts, and whenever that number of restarts is exceeded, Monit will stop monitoring the process. This is done to avoid filling your email inbox with repeating notifications, and is also effective since you would get the emails anyways, from the first restarts. You can learn how to monitor SABnzbd with Monit in this Monit setup guide.

Monit: Monitor Webmin process status

Monit And Webmin ConfigurationLearn how to configure Monit to work with Webmin and keep it monitored. In this tutorial you will find out how to keep Webmin active on your Ubuntu server.

What happens if you try to connect to your server through Webmin, but it has failed before that? You won't be able to connect. With Monit, you can be notified when the Webmin process fails, and also let Monit attempt to restart it, to keep it always active on your Ubuntu server.

Monit: Monitor qBittorrent process status

With this Monit setup guide you will learn how to configure Monit, in order to ensure that your qBittorrent process is always active, as well as notifying you via email if some problems arise with this application on your Ubuntu home server.

Monit: Monitor Transmission process status

Monit And Transmission Webui ConfigurationTransmission is another application that needs to be constantly running in your automated home server. With these Monit examples you can learn how to configure this software in order to constantly monitor your Transmission WebUI, to ensure it's always working, restart it automatically in case it fails, and notify you via email.

Monit: Monitor ShellInABox process status

Monit Shellinabox ExampleShellInABox allows you to control your headless (i.e. no monitor attached) server from another machine, even if it's not on your home network. With this Monit setup guide you will learn how to configure Monit in order to restart ShellInABox automatically, as well as notify you via email if ShellInABox fails. This is important if you have remote access enabled, because you may not be able to locally restart your server, so Monit can be set up to attempt doing it on your behalf, which is awesome and adds a level of strength to your fully automated configuration.

With these tutorials you will hopefully get the most out of your Monit installation, and have your home server closely monitored, not only to extend the useful life of your hardware, but also to keep your server working at all times, which is extremely convenient.
