Monitoring the health of servers manually can save you from memory leaks, bad resource-consuming [software](https://hackernoon.com/tagged/software), attacks and downtime.

**TL;DR** `glances`, `htop`, `iotop` and `iftop`

The 4 Tools in iTerm

Installation commands in this tutorial assume Debian/Ubuntu distro and root access, else use `sudo`

### **#1** [**Glances**](https://nicolargo.github.io/glances/)

![](https://hackernoon.com/hn-images/1*ryWYByUYu3M48Kure23JnQ.png)

Glances v2.8 in Ubuntu 16.04

`glances` is, in my opinion, the best summary of the current state of your server. CPU Stats, Memory Stats, [Network](https://hackernoon.com/tagged/network) Stats, Disk Stats and list of top processes (sortable too) and much more!. Additionally, it has configurable warnings for the tracked stats.

You can easily install it with its auto-install script with curl or wget:

curl -L http://bit.ly/glances | /bin/bash

or

wget -O- http://bit.ly/glances | /bin/bash

If you have Pip:

pip install glances

### #2 [htop](https://hisham.hm/htop/)

htop 2.0 in Ubuntu 16.04

I’m sure you all know `top`. Well, `htop` is top on steroids. It adds colors, bar graphs, sorting, filtering, tree visualization, customization and much more.

To install it, just run:

apt-get install htop

### #3 iotop

iotop v0.6 in Ubuntu 16.04

`iotop` monitors your disk I/O. It’s perfect to find out which processes are consuming your disk I/O and come to a solution.

Many distros come with `iotop` installed, but if not just use the following command:

apt-get install iotop

#4 [iftop](http://www.ex-parrot.com/pdw/iftop/)

Slow upload/download speed to/from your server? Use `iftop` and check who is consuming your link! You can see the cumulative transferred bytes and peak up/down speeds on the bottom-left. You can also see the current down/up rates for the last 2, 10 and 40 seconds intervals in the bottom-right.

I suggest using the logarithmic option. Just type `L` in uppercase.

Install iftop using the following command:

apt-get install iftop
