In this article we will show how to monitor your Linux system and some of its metrics by using a simple server monitoring tool that we would like to share with you, called Scout_Realtime.
What is Scout_Realtime ?
Scout_Realtime is a simple, easy-to-use web-based tool for monitoring Linux server metrics in real-time, in a top-like fashion. So It shows you smooth-flowing charts about metrics gathered from the CPU, memory, disk, network, and processes (top 10), in real-time.
Installing Scout_Realtime Monitoring Tool in Linux
1. To install scout_realtime on your Linux server, you must have Ruby 2.7+ installed on your server using the following command.
$ sudo apt-get install rubygems -y
# sudo yum -y install rubygems-devel
$ sudo dnf -y install rubygems-devel
2. Once you have installed Ruby on your Linux system, now you can install the scout_realtime package using the following command.
$ sudo gem install scout_realtime
3. After successfully installing the scout_realtime package, next, you need to start the scout_realtime daemon which will collect server metrics in real-time as shown.
4. Now that the scout_realtime daemon is running on your Linux server that you want to monitor remotely on port 5555.
In addition to If you are running a firewall, you need to open port 5555 which scout_realtime listens on, in the firewall to allow requests to it.
$ sudo ufw allow 27017 $sudo ufw reload
# sudo iptables -A INPUT -p tcp --dport 5555 -j ACCEPT # sudo service iptables restart
$ sudo firewall-cmd --permanent --add-port=5555/tcp $ sudo firewall-cmd reload
5. Now from any other machine, open a web browser and use the URL below to access the scout_realtime to monitor your remote Linux server performance.
6. By default, scout_realtime logs are written in .scout/scout_realtime.log on the system, which you can view using cat command.
$ cat .scout/scout_realtime.log
7. To stop the scout_realtime daemon, run the following command.
