Scout_Realtime is a simple, easy-to-use web-based tool for monitoring Linux server metrics in real-time, in a top-like fashion. It shows you smooth-flowing charts about metrics gathered from the CPU, memory, disk, network, and processes (top 10), in real-time.
To install Scout_Realtime Monitoring Tool in Linux, follow the steps mentioned below:
1. To install scout_realtime on your Linux server, you must have Ruby 1.9.3+ installed on your server using the following command.
$ sudo apt-get install rubygems [On Debian/Ubuntu] $ sudo yum -y install rubygems-devel [On RHEL/CentOS] $ sudo dnf -y install rubygems-devel [On Fedora 22+]
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.
$ scout_realtime
4. Now that the scout_realtime daemon is running on your Linux server, you want to remotely monitor port 5555. 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.
---------- On Debian/Ubuntu ---------- $ sudo ufw allow 27017 $sudo ufw reload ---------- On RHEL/CentOS 6.x ---------- $ sudo iptables -A INPUT -p tcp --dport 5555 -j ACCEPT $ sudo service iptables restart ---------- On RHEL/CentOS 7.x ---------- $ 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.
http://localhost:5555 OR http://ip-address-or-domain.com:5555
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.
$ scout_realtime stop
8. To uninstall scout_realtime from the system, run the following command.
$ gem uninstall scout_realtime
