I Monitored My Network with Grafana (2024)

Welcome to my channel! In this video, I will walk you through the process of setting up Grafana and Prometheus to monitor network devices using SNMP-Exporter.
Here's what you'll learn in this video:
Introduction to Grafana and Prometheus: Understand the basics of these powerful monitoring tools and how they work together to collect and visualize data.
SNMP-Exporter Configuration: Learn how to configure the SNMP-Exporter to gather metrics from network devices using the SNMP protocol.
Using a Grafana Dashboard Template: Discover how easy it is to set up a monitoring dashboard using a pre-made template from the Grafana website. This demonstration shows that you don't need to know how to program to effectively use Prometheus and Grafana.
Whether you are a beginner looking to get started with network monitoring or an experienced user seeking to enhance your monitoring setup, this video has something for everyone.
Here is a link to my github to clone my repo:
github.com/ant...
Where to download grafana dashboards
grafana.com/gr...
Here is how to start
Remember that you need to install docker-compose first.
Then:
git clone github.com/ant...
sudo chmod -R 777 volumes
How to install Node-Exporter
wget github.com/pro...
tar xvfz node_exporter-*.*-amd64.tar.gz
cd node_exporter-*.*-amd64
./node_exporter
sudo mv node_exporter-1.8.1.linux-amd64 /usr/local/bin/
Create a file
sudo nano /etc/systemd/system/node.exporter.service
Paste the following:
[Unit]
Description=Node Exporter
Wants=network-online.target
After=network-online.target
[Service]
User=node_exporter
ExecStart=/usr/local/bin/node_exporter
Restart=on-failure
[Install]
WantedBy=default.target[Unit]
Description=Node Exporter
Wants=network-online.target
After=network-online.target
Save the file
Then add node-exporter as a service by doing the following:
sudo useradd -rs /bin/false node_exporter
sudo systemctl daemon-reload
sudo systemctl enable node_exporter
sudo systemctl start node_exporter
sudo systemctl status node_exporter

Let me know what you think about Grafana? Leave a comment here..

[@vijaiy1]

Great explanation! Thanks for explaining :)

[@edersilva7591]

Thanks for explanation, nice video

[@AntonioPersianoTech]

Thanks for commenting and liking my video.

How do I change the IPs in the Prometheus.yml file to match my ipconfig? When I run sudo vi prometheus.yml edit. It informs me there is a swap file lock detected.

[@AntonioPersianoTech]

Try stopping prometheus container first, edit then try starting it again.

i want monitor Mikrotik router is it possible?

[@AntonioPersianoTech]

Yes if it supports snmp which mikrotik does then you can.

Great video, do you happen to collect logs with Grafana Loki ? Been looking for videos that walks through a setup where it collects syslogs from embedded devices.

[@AntonioPersianoTech]

Thanks for your kind comment. Yes I have run Loki to collect logs, maybe its an idea for another video. 🤔 Are you currently using grafana with prometheus to monitor your devices?

[@dreeastwood2500]

@@AntonioPersianoTech would love to see how your handle logging because I cannot for the life of me get to work (especially since promtail is gonna be deprecated and “alloy” is replacing it) And no not yet, using netdata rn to get metrics.
