How to configure the Glances Monitoring Tools on Oracle Linux 9.3
To Configure Glances Monitoring Tool On Oracle Linux 9.3
Introduction:
Glances is a versatile monitoring tool designed to display a wide range of system information through either a command-line or web-based interface. It offers insights on memory, CPU usage, disk input/output, file system status, uptime, running processes, network interfaces, alerts, and various other system metrics.
Procedure Steps:
Step 1: Check the OS version by using the below command.
[root@linuxhelp ~]# cat /etc/os-release
NAME="Oracle Linux Server"
VERSION="9.3"
ID="ol"
ID_LIKE="fedora"
VARIANT="Server"
VARIANT_ID="server"
VERSION_ID="9.3"
PLATFORM_ID="platform:el9"
PRETTY_NAME="Oracle Linux Server 9.3"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:oracle:linux:9:3:server"
HOME_URL="https://linux.oracle.com/"
BUG_REPORT_URL="https://github.com/oracle/oracle-linux"
ORACLE_BUGZILLA_PRODUCT="Oracle Linux 9"
ORACLE_BUGZILLA_PRODUCT_VERSION=9.3
ORACLE_SUPPORT_PRODUCT="Oracle Linux"
ORACLE_SUPPORT_PRODUCT_VERSION=9.3
Step 2: Enable the EPEL Repository by using the below command.
[root@linuxhelp ~]# dnf install epel-release

Step 5:- Add a firewall rule for Glances web port so that the web console would be accessible.
[root@linuxhelp ~]# firewall-cmd --zone=public --add-port=61208/tcp --permanent
success
[root@linuxhelp ~]# firewall-cmd --reload
Success
Step 6: Run the below glances command to monitor your local machine.
[root@linuxhelp ~]# glances
Step 7: If you want to remotely monitor your machine, from any device with a web browser, just run the glances with the -w option.
For this to work, we need to install the Bottle module -- you can install this module using pip command.
[root@linuxhelp ~]# pip3 install bottle
Requirement already satisfied: bottle in /usr/lib/python3.9/site-packages (0.12.21)
WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv
Step 8: Run the below command to remotely monitor a machine
[root@linuxhelp ~]# glances -w
Glances Web User Interface started on http://0.0.0.0:61208/
