How to Install Service SNMP on Linux RHEL 8 for PRTG

How to Install Service SNMP on Linux RHEL 8 for PRTG - Hi friends, Good morning and welcome back to my personal blog. On this occasion, I will write a simple guide on installing SNMP agent on client servers for monitoring with PRTG Network Monitoring.

Paessler PRTG Network Monitor

One excellent and real-time monitoring tool that you can also purchase is Paessler PRTG Network Monitor. With tools like this, you will find it easier to monitor the utilization of your servers, networks, and applications, enabling you to be more attentive when issues arise in your IT devices and use the logs as a starting point for problem-solving.

In this example case, I will be adding a server with the Linux RHEL 8 Operating System. Okay, let's go straight to the guide on adding a device for monitoring in PRTG. Here are the steps:

Preparation

Make sure your local repository or internet repository is active in order to install the SNMP package. If it's not active yet, you can refer to the guide on setting up a local repository.

Installation

# yum install net-snmp net-snmp-utils -y

Install SNMP Service on Linux RHEL 8 for PRTG Network Monitoring

Configure

Edit the SNMP configuration using the following steps:

# vi /etc/snmp/snmpd.conf

In the first configuration, I create a custom community name, which is essentially 'public'. Replace it according to your preference or the policies in your company.

# First, map the community name "public" into a "security name"

#       sec.name  source          community
#com2sec notConfigUser  default       public
com2sec notConfigUser  default       kitsake

Custom Community Name

Also, add the following line to your configuration:

#view    rwview          included        snmp.snmpEnableAuthenTraps
view    systemview          included    .1.3.6.1
view    systemview          included    .1.3.6.1.2.1.25.1.1

systemview

Restart service SNMP for apply configured.

# systemctl restart snmpd
# systemctl enable snmpd

Trying to add a Linux Server to PRTG

After configuring the agent inside the client server to be accessible from the server using the created community, now we just need to go to the existing PRTG server and add that client.

Adding Device

Open PRTG Network Monitoring - Right Click Add Device

Open PRTG Network Monitoring - Right Click Add Device

Input Device Name - Input IPV4 Address/DNS Name

Activate Credentials for SNMP Devices - Input kitsake

Activate Credentials for SNMP Devices

Adding Sensors

Now, after adding the device within PRTG, the next step is to add the sensors that we want to monitor in PRTG.

Right Click on Device - Click Add Sensor...

Adding Sensors

Select the sensors that you want to monitor :

Search : type snmp - choose sensor

Sensor Types with SNMP

Here, I am monitoring my server with the following sensors:

• Ping
• SNMP CPU Load
• SNMP Disk Free
• SNMP Linux Meminfo
• SNMP System Uptime
• SNMP Traffic
