Monitoring with Grafana InfluxDB and Telegraf

Introduction

In this tutorial, How to monitor your system using Grafana InfluxDB and Telegraf. This article will guide you through the process of setting up and using these tools, from basic configurations to advanced monitoring techniques.

What is Monitoring with Grafana InfluxDB and Telegraf?

Monitoring with Grafana, InfluxDB, and Telegraf involves collecting, storing, and visualizing time-series data. Telegraf is responsible for gathering data from various sources, InfluxDB stores this data, and Grafana visualizes it through customizable dashboards.

Benefits of Using Grafana, InfluxDB, and Telegraf

1. Real-time Monitoring: Visualize data in real-time to quickly identify and address issues.
2. Scalability: Easily scale your monitoring setup to handle increased data volumes.
3. Customization: Create personalized dashboards to suit your specific monitoring needs.

My example is Grafana InfluxDB, Telegraf as in the picture below:

• Server01 -> 192.168.3.5
• Server02 -> 192.168.3.6
• InfluxDB and Grafana -> 192.168.3.4

Install Grafana Influxdb and Telegraf on Linux

• InfluxDB
• Grafana
• Telegraf

Configure Grafana InfluxDB and Telegraf

InfluxDB configure

For my example, create 2 Databases with a 14-day retention policy.

[root@DevopsRoles ~]# influx
Connected to http://localhost:8086 version 1.7.6
InfluxDB shell version: 1.7.6
Enter an InfluxQL query
> show databases
name: databases
name
----
telegraf
mydb
_internal
> CREATE DATABASE mydb WITH DURATION 14d
> CREATE DATABASE telegraf WITH DURATION 14d

Open and edit the file /etc/influxdb/influxdb.conf as below

[[opentsdb]]		
   enabled = true		
   bind-address = ":4243"		
   database = "mydb"		
[[opentsdb]]		
   enabled = true		
   bind-address = ":4242"		
   database = "telegraf"

Telegraf Configure

For example, create file configuration as below

$ telegraf -sample-config -input-filter cpu:mem:swap:net -output-filter influxdb > telegraf.conf

Edit and modify the file /etc/telegraf/telegraf.conf for server01

[[outputs.influxdb]]		
  urls = ["http://192.168.3.4:8086"]		
  database = "telegraf"	

Grafana Configure

Add Data Sources for InfluxDB of Server01 as in the picture below

Import the Telegraf JSON template as the picture below
